Would someone on here please post a couple of link's for me to go to which will explain exactly how to do it?
I realize there have been numerous link's posted, but I don't make it and I don't shoot it so I never paid much attention to the links.
I just want to read about it and all I know how to find on my computer is where to buy it at..Many thanks for your help....

Beagle-Zebub..Thanks!!
Reading this will help me pass my weekend and maybe learn something to.
I didn't know exactly how they done it. I knew the ingredients and all and about milling it and whatnot, but after that I was kind of lost.
I knew that like anything else there was an art to it.
This link you posted appear's to be some real good reading, and I appreciate you taking the time to post it for me....

Ingredients needed: 99%+ pure; Sulfur, KNO3 ( Potassium Nitrate ) and Willow or Alder Charcoal

Materials needed
1: ball mill aprox. 1 gallon size, with half the jar filled with .45 to .50 hardened lead balls ( mill media )
2: Screens/strainers to sift out media and to granulate BP
3: Digital scale: 500 gram minimum +/- .01 gram accuracy
4: Other useful: Isopropyl Alcohol, pyrex measuring cup, plastic buckets, wood spoons, storage for finished BP

*Steps;
#1: Weigh; 75% KNO3, 15% Charcoal 10% Sulfur. For a 500 gram batch ( just over 1 lb ), that's 375 grams KNO3, 75 grams Charcoal and 50 grams Sulfur. Weigh each separate and zero scale each time for accuracy. Pour all powder into mill jar with media already in jar. Seal mill jar.

#2: Run mill 3-6 hrs.

#3: Empty mill jar into strainer over newspaper or bucket, sift out lead, place back into jar

#4: Powder is now "mill dust" Black Powder, it can be granulated next...

#5: Wet powder with water and about 10% alcohol to aid absorption into dry powder. Mix by hand or spoon until it's a clay like consistency.

#6: Rub the ball of BP through screen to granulate, dry outdoors, not in direct sun ( slow drying makes better BP )

That's it, store properly. This powder is more fragile than commercial, since it's not been compressed to 1.7g density, it takes up more space per load, but is more powerful too.

"Clay-like consistency" means a stiff clay that almost crumbles. If you get it too wet, you won't be able to screen it. (don't ask me how I know this)

JCT
March 15, 2008, 04:34 PM
I've over wet it more than a few times. It'll clog up your screen and make large grains of BP, too big for revolvers.
Moist enough to bind the BP, but dry enough to allow it to be screened into the size you want. I'm not picky about fffg, ffg size. Homemade powder ends up being a mix from ffffg to fg, but works great and is so clean!! I shot about 50 rounds through the Walker yesterday and couldn't see fouling except on the base pin, chambers were clean, bore was clean! Hotter BP= cleaner BP. I most likely won't ever use GOEX again, but I would buy and use Swiss if it were sold anywhere around here, just for the convenience and durability of commercial BP. My homemade doesn't work well in the powder flasks, probably because I leave to many bigger chunks of BP in there too. Sometimes, I just use a lee dipper or powder measure and work from a container of my BP.

Beagle-zebub
March 15, 2008, 05:37 PM
JCT, do you get reasonable accuracy with your powder? The thing about the grain-size being all over the place made me wonder that.

EDIT: Also, it seems like fireworks people believe that higher density is a good thing, which they put into action with big presses. What's the deal with that. Both you and the Swiss website that I originally posted would seem to contradict that, even accounting for the fact that the firecrackers aren't worrying about messiness.

You being able to get off fifty shots from your Walker is danged impressive! Now I'm even more excited about this stuff....

JCT
March 15, 2008, 07:08 PM
I'm getting good groups, all my BP revolvers shoot high, but I'm working that out lately too. I just don't think the grain size makes enough difference. I also remember reading about a mix of FFg and FFFg that used to be used for revolvers for some reason.
Firecrackers are usually made with a different powder altogether; Flash powder, which is still a fuel oxidizer mix ( KCLO4 and Aluminum powder ).
Fireworks use all grades and densities of BP. Lift powder is usually pressed, but doesn't have to be. Powder for blackmatch fuse, rockets, fountains..etc is unpressed, mill dust BP, just like mine. They use mallets and rammers to load the cardboard tubes and create the solid fuel grains.
I've never tried Swiss BP, but may break down and order some this summer to compare to mine. I'll have to buy a chronograph someday too just to be more scientific when working up loads. I like how the fouling stays nice and soft when using real BP, that's an advantage over the substitutes which seem to have dry and hard fouling.
I almost got into pressing my homemade powder, but it's just not needed. While a 50 grain spout of my powder probably only weighs as much as a 45 grain spout full of GOEX, the power is greater. The lower density may also allow it to burn faster. I don't bother with the spouts most times, I can just fill the cylinder and since my powder will compress, I can fit the wad and ball still and it ends up being a good load.

This website is pretty stinkin' great.

I ran across the musketeer site long ago and it is good.

He even demonstrates he made saltpeter from naturaly occuring saltpeter from a wall. It was just as effective even with some contamination. However contamination can easily be removed (and for general use should be as it can be hard enough to scratch the barrel.)


Some additional highly valuable information:

Saltpeter can in fact be made by anyone just be leeching soil if necessary. Essentialy it can be made from animal waste, (even human waste, but for the same reason they don't use human waste for agricultural purposes you should avoid that.)
A really informative reading would be to look up early salt peter production.
Specificly Nitre beds.

That will teach you how to make black powder from scratch even in a doomsday scenario with no chemicals or commerical products.

Bottom line, you could make gunpowder from your own bodily wastes if you wanted.
Of course you could also make smokeless powder and even high explosives from scratch by making some acids from scratch, nitrating and then purifying various things with everything you could aquire on a deserted island.

Some of the most informative reading when read with the understanding of modern chemistry is very old historical alchemy experiments many done as early as the 800's. They are some of the simpliest, and generaly use materials you could collect outdoors.
Be sure to double check them with modern chemistry, but the correct ones are great.
Knowing such information could allow you to make even some of the most powerful modern explosives and propellants on a deserted island so is quite valuable.
Such information is also very important to spread as with it widely known it is appearant that firearms and firearm technology could never be controlled or eliminated.

Of course currently you can just purchase saltpeter and sulphur, and make your own charcoal (the most important part.)

There is various methods to combine them. JCT gives a great one.


For safety purposes be sure to use all non sparking equipment. For an electricly powered mill that includes making sure no fine powder will reach the motor (and some can become quite fine dust). Many mills also come with or suggest steel media or ball bearings for other purposes. DO NOT USE any material that will or can spark, including iron or steel. Lead works well for this purpose.

I am a farmer and I use to get Potassium nitrate to spray on my cotton in late season. What we call spoon feeding it. Now you can't find a source. You can't buy ammonium nitrate any more. The only thing I can buy in bulk is Urea which is 45% CO(NH2)2. The twos should be subscripted in the last formula.
Can Urea be use to make bp?

Spray-grade KNO3 fertilizer is still available (but it's hard to find) and it should be high enough purity to use for making BP. I think it is just technical grade, which is what you want. Prilled KNO3 fertilizer can also be used, but you'll probably have to purify it to make *good* BP.

Urea won't work at all. It's not oxidized nearly enough.

From what I read on Ulrich Bretscher's Black Powder Page, I could extract saltpeter from the manure collected from my friend's stable..........she also has a large willow tree........hmmmmmmmmm :evil::evil::evil:

I wonder what practical amount of time is required for the process.........I guess however long it takes to boil down the "brine"???

GENTLEMAN OF THE CHARCOAL

Yeah, I'm learning a lot here. Good way to spend a weekend.
I heard a long time ago or read it in a book somewhere that you can get all the nitrate you need under the cow piles.
I also know where there's a couple of pools of sulphur water. That must mean there's lot's of sulfur in the ground there. I'll have to find a site and read on the computer maybe how to get it from the soil. Hell, it might just lay around in chunks like rocks for all I know.
I know I drink a lot of coffee and I piss a lot. I think what one would have to do is place the urine like in a can and cover it with a cloth. The cloth would allow the moisture (steam) to escape and would also hold in the nitrate.Probably be kind of smelly but it's better than dying. I'vd also got to find out about cow piles and how to get the nitrate down to a reasonably pure form. (if I can)....

United Nuclear sells Harbor Freight tumblers at a huge markup. These mills will make decent small batches of BP, but buy the mill from Harbor Freight for about $25!!
Steve Baron at Micropyro has a great reputation for good prices and quality charcoal, but it's so easy to make your own if you have Willow or Alder.

I see harbor freight has 2 sets of tumblers, but I am not familar with either.

It causes me to wonder if the double drum has the same motor the single drum has.

This causes me to wonder if the double drum motor is stronger and so using a single drum on the double drum frame might be a way to go.

JCT, Would it be a bother to get a pic of the drum up as well.

This photo is far better than the others, as i can see the const better.

What are the rollers from, possibly a larger scanner printing bed?


If you know what is the rpm of the drum?

What is the rpm of the motor?

Does the drum have internal fins of any type like a common back yard cement mixer does?

As an aside I can see working backwards and getting to a mortar, but I'd rather use water power if no other was available to drive a drum. Time is still time.

All that work he put in with the mortar and pestle and his BP didn't do so well in the test at the end. See all the large sparks in the air? These are large particles of charcoal that were not ground well enough. It's usable powder, but most likely not as good as commercial powder. A good mill makes a huge difference.
You can mill about a 150g batch in the small harbor freight mills. Use buckshot or a handful of hardened lead ball for media.

Just to verify........150 GRAMS, correct? About 1.3 lb?

JCT

150 grams is .33 lb ( 1 lb is 454 grams ). That's about all you can effectively mill in the Harbor Freight mill, I have one and started with it. It works well enough though and is what I still use for test batches if I try other woods or make different mixes for BP rockets.

March 17, 2008, 02:11 PM
You could use a meat grinder to pulverize the charcoal before milling it, but that's about it. A Corona grain mill would get you a lot closer. I just crunch it up with my hands (wear a dust mask)

JCT
March 17, 2008, 09:43 PM
You don't need airfloat charcoal anyway when making BP. The course charcoal will soon be airfloat when in the mill with the S and KNO3.
When the mill walls are caked and the BP is caked into big dense chunks, then you know you have good BP and you're mill is working right.

There's a Harbor Freight right down the street from me. I went in there tonite and they had both models. I'll reserve my opinion of them for now, but the display models didn't impress me much......maybe too much handling.

mortor and pestle on its way
I would not use a mortal and pestle.
Black powder can be set off by both static electricty and sparks. A tiny piece of metal or impurity could spark causing explosion during grinding.

The risk of an accident is low with proper and safe techniques, but it is always there even if reduced to something small. With a mill you can be removed from the danger zone throughout most of the process.
With a mortar and pestle you will likely lose your hands from burns, and perhaps your eyesight, along with serious burns if you ever have a problem.
Lots of static in the air? Might be your last day of eyesight, so be sure to enjoy the ability to see now!

The individual components are one thing, but actualy combining it in a pestle is a risk I wouldn't decide to routinely take.

mykeal
March 21, 2008, 08:38 PM
The static electricity legend has pretty well been debunked by now; sparks are an issue, however.

Black powder is ignited by heat, not electricity. It is a conductor, not a resistor, and as such will not build up heat when subjected to an electrical charge; it simply passes the electrons through.

However, there is still a danger: if the powder is contaminated with small bits of metal or a resistive material that does heat up when subjected to electricity, that heat buildup could cause ignition of the powder. The bits of metal become, in effect, sparks, such as those given off by a flint scraped on hardened metal.

The use of a mortar must consider whether the scraping motion results in enough friction to heat up the powder locally and thus cause ignition. The mortar and pestle materials certainly play a part in that, as does the speed of the grinding motion.

JCT
March 21, 2008, 08:47 PM
Making BP is no more dangerous than using BP when loading your gun. I've seen first hand, archs from electricity and static generators, that won't set off BP. It's possibly the most stable "explosive" in existence. It's a fuel/oxidizer mix, not a true "explosive" anyway. A mortar filled with BP can burn you, but that's it, you won't have an open air explosion with BP until it hits it's self confinement point, around 500lbs of BP for that.
You should be wearing safety goggles and leather gloves, as you would for any safe lab procedure anyway. People are quick to condemn what they don't understand....
Pyrotechnicians commonly work with far, far more dangerous compositions, flash, whistle, etc...they do explode in open air and are friction, static, and impact sensitive, yet they can be worked with safely and never have accidents if they use common sense and common safety.

Pyrotechnicians commonly work with far, far more dangerous compositions, flash, whistle, etc...they do explode in open air and are friction, static, and impact sensitive, yet they can be worked with safely and never have accidents if they use common sense and common safety.
I have worked with such things myself.

Hand grinding a highly combustable mix of dry chemicals just does not pass the safety test, even a mixture only marginaly susceptible to friction ignition.

Working with a pile of it by hand is different than intentionaly applying large amounts of friction to something which is intentionaly unstable and can explode or in this case deflagrate, while standing over it, with your hands and arms right in the direction the heat and energy would be directed. A minor impurity in the mix could leave the person disfigured and possibly disabled for life.

Making black powder can be safe. However an error, even not due to the individual and instead the supplier of a chemical or an impurity from another item getting in the mix can be disasterous.
In a mill the low chance of problems from someone taking proper precations is acceptable in small batches, especialy in a mill located in a location that even a minor explosion poses little risk of harm to anyone.
In a mortar and pestle that low chance just became unacceptable in my opinion.

Even factories that produced black powder were made so that in case of an explosion the forces would be directed in a harmless direction, usualy through one wall intentionaly built to give.

While this would instead burn rapidly and not explode, the same concept applies. The direction of the burning and heat would be straight up from the pestle. Right where the hands, arms, and possible face of the person is.
That is simply not a safe practice.

If we have different opinions on acceptable risk that is fine.

JCT
March 21, 2008, 11:23 PM
Black Powder is not friction or impact sensitive though. If for some reason there was some perchlorate impurity in the KNO3 ( most likely impossible...) then there'd be a slight, possible, remote chance of friction ignition, but that same impurity would bow up your ball mill during operation too. I've never heard of one single account of BP going up on anyway in milling, rocketry, pyrotechnics...etc. It's quite stable.
In a mortar and pestle, you have to grind a small amount anyway, I can't imagine that you can do more than 100 grams at once in a average size mortar. Still best to follow safety anyway ( gloves and goggles ). I'd use a ceramic mortar.
Grind all 3 ingredients separate at first so they're all super fine powder. Then mix the 3 and work them together until homogenous.
Personally I wouldn't bother much with a mortar and pestle, it's a nice idea, if you have no power or no mill, you can make your BP this way, but why not just mill up a bunch now and store it so when you have no power and have to be self reliant....you have plenty of BP ready to go! A mill will make better powder than you can do by hand anyway.

March 21, 2008, 11:33 PM
im going to have to agree with jct especially when there is about a hundred or so videos on all video hosting networks showing people make it this way. im not going out to make a 5lb batch. im going to try to make as small amount as possible im going to try to see if i can duplicate or make better than goex. Im sure its possible. but id rather start out small. then if it works get a mill. Same time people have been making black for thousands of years. only about for two hundred years was man using a mill. Mills im sure were first powered by water then steam then gasoline then electricity. but before that it was mortor and pestle. Same time there are so many different mortors and pestles out there to do the job. Safety of course is my main concern and will be followed.

Would have stayed longer. I wanted to put up another target but she kept jaming up on me. Then was not setting off any of the caps. Had to come home with three cylinders full of powder and balls. Once i got home i completely took her apart. there were about 4 pieces of old caps in the works. Now she is already for next week. I think i must have had to much oil on the works to around the cylinder that made the caps jam up in the inside. I wish they made caps that would not fall apart on you when you pulled the trigger wouldnt that be great. Im thinking about ordering some new nipples to get a better fit. so question i have for you guys whats a good brand of nipples for a Uberti

Scalper, I had typed all this, but your thread got closed!!:

There's at least 2 or 3 recent threads all about making your own BP. At least a few people here and at TFL make their own.
The most important variable is the charcoal. Low density hardwoods seem to be the way to go. I use Willow, but Alder, Balsa, Paulownia and Grapevine work great ( I've tried all but Paulownia myself ). Willow makes fast and hot BP. Hot BP= clean BP since the combustion leaves little residue.
There's no need to make anything other than the standard 75% 15% 10%, KNO3, Charcoal, Sulfur. You could leave the sulfur out, but it's there for a reason. It lowers the ignition temp of the oxidizer/fuel mix and regulates the burn for a consistent and even reaction. This is where products like Pyrodex and 777 can have issues and non fires at times. They have very high ignition points, good BP doesn't.

Aromatic cedar, or just plain red cedar? (white would be better)

I used a cedar fence picket to make charcoal and it worked really well. I still haven't been able to properly test the gunpowder because of the weather. (the first time I tried it, in .45 Colt cartridges, they sort of went "Thbbbt!" instead of "BANG!", but the powder was still damp)

JCT, Whats the deal with maple sugar then? Everyone uses white pine to boil of the sap. So is the 'niter' sugar sand something to save?

scrat, Fruit woods are usually hard, real hard, and make good mauls and wood chisel handles, besides good woods to use in a smoke house.

I never got to play with any of eucalyptus, or even read about it, so I can't help on that score.

Knowing the properties of alder, a shrub like tree right where I hate them fly fishing, and willow are, I would bet that some desert cactus would make dandy charr.

I have linden wood also called bass too. One I wonder about is larch, also called tamarack. This looks like an ever green but isn't. amd once dry works well for a bow drill.

Making charr is what you do with a bow drill to get fire, so I suspect stag horn sumac might also make good gun powder char.

I just don't know if there is any in cal.

With that said I wonder if the stalks on mullien wouldn't make a good charr for BP in guns too?

So many little plants, so little time..

When I was in Cal, it was on a big fat bike, a Nomad. Traffic in Cal is a tad fast to look at trees too. Never the less, I managed a good long glimpse of a brown bear just the same!

Willow, Bass, Alder are not resinous woods, and not very hard woods either. More or less cedar isn't really resinous.

I wonder if eucalyptus might be in the cedar family? I hear cedar like trees in different names than I am accustomed to hearing, and so I wonder if this might be one of them?

If you can get a stick from one and whittle on it some, maybe inspect the tree for pitch, and find none, it could be something with in reason.

You could charr pine, what ever that means as we have a lot of different pines here.

That way you can see how light pine is and compare to that with eucalyptus and a little store bought cedar. Can you buy real red wood anymore? I once worked with that wood and while it was rot resistant, I never found any pitch.

JCT
March 25, 2008, 12:02 PM
I would think the sediments and debri while boiling sap are just silicates and dirt from the tree. I don't think it's of any use.
There's plenty of concord grape in NH though, grapevine makes good BP. I think any low density hardwood ( sap, not pitch ) should work good. I made one small batch with store bought balsa once, it might be the hottest BP I've seen, but the balsa is so light, it's hard to work with and to mill real well.
The only problem with Willow is that it's not native here. Usually willows are in peoples yards. You can check golf courses, they always have them and trim each year. Swamp alder is easy to find and is just as good as Willow. Swiss BP is made with Alder.

Macmac
March 25, 2008, 07:46 PM
Yes there is a yard willow here, that I could get branches from.. Alder is more common. No native grape right here in my woods, but i know it is around. It was common wild in the area in Mass north of Boston.

When I can get grape vine bark I will collect it as a good source if tinder.

The coment I was wondering if it was real came from you and the bit on cats and maple sugar. I just washed my filters so that mung is gone.

I guess it was more a joke than any real recipe for maple sugar at all, but since I am making maple sugar, I wanted to be sure it wasn't the sand that forms at about 217' degrees.

I hear ya on balsa, and while I don't know, after charring that I might dampen it and mill it alone, just to give it weight.

My idea is to learn and mimic your way as best I can, then take that education and work it in reverse for a no power what so ever tech, so I will bnever again be with out powder for so long as the wind blows and the rivers flow..

What I like best is the fact you claim I can make better powder than I can buy. I can't beat that with a stick 10 feet long.

I will have no choice but to buy KNO3, and sulfer. A small problem just now is being between any decent work. I get by finding odd jobs right now, but when summer comes I hope to find better working conditions.

Then get the tools I have learned about reading all this information.

I am sure there is alder right here along side the brook, just now that one for me is hard to tell from witch hazel. Not to mention I have something everywhere call snow 3 to 4 feet deep! Most of those little trees are 7 feet tall and only the tops show today.

This thread is very thorough about making BP, however, I guess I am puzzled about how to make the various powder sizes F, FF, FFF, and FFFF. I understand that you use screen with bigger holes and you will get bigger pellets of powder.

Can we get a bit more specific? I am after BP for my revolver so I am kind of after FFF. If I make it too fine like FFFF, what will happen to my revolver? Will it still work? How will this increased burn rate affect me (accuracy, residue, etc)?

zxcvbob
March 26, 2008, 11:37 PM
Compressing it has to be a good thing, but JCT says his powder is quite good without it (because he uses better charcoal than Goex does)

In another week or two it should be dry enough here that I can test my powder again. I didn't compress it because I don't have a hydraulic press (and the pressing and corning is a little bit scary) My powder looks about like commercial FFF but it's duller in color. I used very good charcoal and very impure KNO3 and sulphur. (I don't think the low-grade sulphur matters, but the KNO3 and the charcoal do)

I'll look for a local source of good KNO3 this summer.

JCT
March 26, 2008, 11:51 PM
Pressing makes a denser and more durable grain. It allows you to fit more BP into a smaller area. Those are the advantages.
My unpressed powder, since it's less dense, takes up more space for equivalent weights of pressed powder, an example a 50 grain spout throws 46 grains in weight of GOEX. The same spout throws 37 grains in weight of mine. This is good since I don't shoot max loads anyway and 37 grains of my powder is as powerful as the 46 grains of GOEX.
I can fill my .45lc cases to the top with my BP and seat a bullet to compress the powder. In weight, it's about 27 grains of BP, perfect really. Using GOEX would give me just about 35 grains. 35 grains is a heavy load in a SAA, but to back it off, you need wads or fillers. With my less dense powder I need no fillers.
I've tried dust straight from the mill, it fires fine, but is messy and hard to deal with in a powder measure. Granulating it is easy.
Also, I think the lower density grains allow the BP to burn up faster which yields more initial pressure, which should mean more accuracy.

Could you compensate for using less or no sulphur by corning/sifting to a smaller grain-size?

JCT
March 27, 2008, 02:03 AM
you can leave out Sulfur if you like, it'll raise the ignition temperature though and the BP will probably not burn as hot or fast, which would mean it'll be dirtier.
At least a few times I've shot the Dragoon or Walker and not cleaned until 2 days later and I never see signs of rust. I think substitute powders are more corrosive anyway.

Why go through all the bother of pressing the powder, then letting it dry and then pound and crush it in order to make it into grains? Would it not be possible to take a pressed cake and force it through a screen before it dries? I understand that the finished product may have a density less than commercial but surely would be more that unpressed powder?

That description about pressing the powder into a puck is a little misleading. The powder should be pressed at a high enough pressure that the sulphur plasticly flows and binds it all together. (I doubt that you need any water at all for this to happen.) The puck will be too hard to grate it or screen it without crushing first.

JCT

You don't need water when pressing BP. The pucks you end up with remind me of clay pigeons or bricks. They're rock hard, you need to break them up to use any of it. I've pressed BP on a small scale, with comet pumps and star pumps, I just find that unpressed powder works great too.

JCT and others have mentioned that sulfur is not required when making BP. However, he did say that the ignition temp will go up. Seems like the stink and maybe some corrosion might go down (just a hunch).

So two questions for anyone who knows:

1) What are some successful proportions (like 80% KNO3/20% charcoal) used by others in making sulfur-less BP?

2) What other properties are noticeable from leaving sulfur out? Projectile velocity? Pressures? Corrosive residue?

sugar is just another fuel, you can just use KNO3 and sugar only if you like, that's getting closer to pyrodex, which I think uses fructose and KCLO4.
Sulfur is a fuel too, but I think it's role is as a catalyst or stabilizer. I'd have to read up again about that, I see no reason not to use sulfur, we all clean the guns after shooting anyway, the smell is part of it all :D

Check the local garden centers for "dusting sulfur." It's only 90% pure though, so don't go hog wild with it until you've made a small batch of BP and tried it. (I think the purity of the sulfur is the least important of the ingredients, but I don't have any data to back that up)

Potassium nitrate-----------70.5------------80---------87.1---------70
Charcoal--------------------29.5-----------20---------12.9----------30

and they had this interesting one under rocket propelleants:D......

NITRATE/SUGAR BASED PROPELLANTS
----------------------------Candy propellant------Teleflite propellant
Potassium nitrate-----------------74.5--------------------63
Sucrose--------------------------25.5--------------------27

I make BP rockets too, the only major difference is they use some air float charcoal, but some course charcoal too for tails. The KNO3 percentage varies depending on rocket size, but is between 65% - 70%. I add 3% baby oil to all that BP which keeps dust down and makes solid fuel grains that don't crack easily, so they don't CATO ( Blow up ).

Oh, I understand and agree with that. But I had the dusting sulfur and the stump remover already, and it is doing a fine job for a "proof of concept" batch of powder. I think the 10% impurity is probably insignificant because S only makes up 10% of the mix, so it's only 1% impurity in the final product -- and the sulfur is the least important ingredient. The limit with my ingredients is probably gonna be the impurities in the stump remover. I should either purify it next time, or find a much higher-grade source of potassium nitrate.

You can't improve on what is already perfect.

Still, curiousity gets the best of me. And this sugar/KNO3 version really has me curious too, since apparently some of the substitutes use fructose, obviously a close chemical cousin to sucrose. It makes me wonder what the reasons for using carbs was? Was it to burn cleaner?

I am also curious what 'rocket fuel' it might do to the old chronograph.:D

sugar is very hygroscopic though, it'll make your powders clump and pull moisture from the air.
The only think I'd be interested in trying someday would be "Benzolift" . It's about 2 times more powerful than BP. It's a mix of whistle mixture ( KCLO4, Sodium Salicylate and Iron oxide ) and Black Powder. Pyros use it for lift charges, rockets, burst charges....etc. It's supposed to be very safe to deal with, and might make a good gun powder. I'd definitely want to do some tests first.

It occurs to me that if you were to perform mass-spectrometry on a sample of charcoal that had been well homogenized, you could find out the optimum proportion of KNO3 for that sample, unless not all the atoms that could react with the KNO3 were able to break the molecular bonds of the charcoal; even if that were the case, it might be easy enough to figure out from the atomic proportions in the charcoal what the composition was, with particular interest towards finding parts of the molecule(s) to rule out as reactants.

Where, you might ask, would one find a mass spectrometer? Well, I know my old high-school had one, so that's the one I would try to use. You might be forced to consult a company like LabCorp, which may or may not be worth your money.

I loaded six .45 Colt cartridges with about 27 grains of my powder (stump remover, garden sulfur, and cedar charcoal) and a 230 grain bullet. I could have got about 28 or 29 grains of powder in if I had really compressed it. I also took a couple of smokeless powder cartridges with the same bullet for comparison. (I think they were 7 grains of Red Dot, but they might have been 7.5 grains)

I just had a few minutes to shoot outdoors before going in to the indoor range where I was on duty tonite.

The powder worked great. The recoil was about the same as the smokeless loads. Of course they sounded much different. BOOM! I was just taking one-handed quick shots at a 9x11" target someone had left set up at 75 feet, and all 8 rounds hit the target.

I have 2 more pounds of stump remover that I bought on clearance at Walmart for $1 a pound. This summer I'm gonna check at all the grain elevators and farm co-ops around here to see if any of them sell (or can get) "spray grade" potassium nitrate. It should be less than $20 for 50 pounds, the hard part is finding it. I could order a bag from a place in Florida, but it would cost $50 to ship it that far.

The garden sulfur obviously is good enough. The stump remover KNO3 is good enough but probably has much room for improvement.

I've been reading this and thinking about whether I want to try it or not. One thing that came to mind was that my wife has started buying hardwood charcoal in 10 lb bags. I'm not talking briquettes either, it's actually chunks of charred wood. The name of the company is Ozark Oak. It doesn't say exactly what trees they use but I'm pretty sure we can assume it's mostly oak. When I googled it there was some speculation that it might have some hickory in it too. I believe she gets it at Wallyworld for $5 or $6 a bag. Anybody know anything about oak and/or hickory in BP?

This is really good news ZXCVBOB. I already have my saltpeter (10 pounds) and the willow charcoal (2 pounds) enroute. Now all I have to do is head to Wallyworld or some other garden shop to get the sulfur and I'm in business. I am figuring that I will be paying about $50 for 13.33 pounds of BP. So the final tally is about $3.75 a pound. Since I get about 350 shots out of a pound (I shoot 20 gr in my BP revolver and 7000 gr=1 lb), that works out to a little more than a cent per shot (for the propellant only). How's that for economy. This has my factory ammo buying non-BP buddies drooling. :-) :-) :-)

I also just got one of those el-cheapo Super Comanches that shoot 45LC and .410 shot shells. I am going to try some BP reloaded 45LC in it on it's debut at the range in addition to my C&B revolver.

Also, just got McLean's book (The Do-it-yourself Gunpowder Cookbook) and he discusses "red-or-white propellant" that uses saltpeter, sugar (sucrose), and ferric oxide (rust). He mentions the hygroscopicity of the final product but I get the impression that it performs about like BP. I know we have discussed the sucrose idea, but anyone know what the rust does? Does it somehow lower the ignition temp or function similar to sulfur?

The iron oxide is a catalyst that speeds up the reaction (I'm not sure how in this case.) The type of iron oxide used is Fe2O3, which is available as red jewelers rouge powder.

I suspect this is more of a rocket propellant rather than a small arms propellant because it would be easily cast or pressed to make hollow tube-shaped cores.

scalper
April 12, 2008, 06:42 PM
It may be obvious to you all, but you only need to measure by weight the first time. Once you know the correct volumes that make up these weights, you can then use volume. Assuming your supplies are relatively consistent, this should work well. Then you can treat it as a recipe (1 cup of this, 2 tablespoons of that, etc.)

Sort of the idea I took away from those little Lee's powder scoops that eliminate the need for a reloading scale. I've used this approach in reloading for years with great success and fewer headaches.

The key is to be careful and double check the weight of your predetermined volumes. It also might be wise to double check the weight when you are using a new supply of raw materials (for instance, the charcoal may not be as finely ground making the volume a bit larger for the same amount of weight).

Sorry, if I am stating the obvious, but thought it might be important to mention since we are talking scales.

I made some dippers (3 each) from PVC pipe and cut them just shy of the proper weight and then top off with the scale. The charcoal is a bit difficult due to the way it settles and or has some small chunks. The Nitrate and Sulphur (if I use Sulphur) work quite well.

I was kinda forced into the following, since I had a major malfunction in the charcoal making process. I ended up with 41 grains of charcoal, which is 15% of 275 grains of KNO3 and then 27.5 grains of S.
Scrat, I'd think you'd want 100, 15 and 10. That would be the 75-15-10 ratio. Don't quote me, but it sounds like you used a bit too much charcoal and S for the amount of KNO3.

Redd - I like the 'scoops made from PVC' idea. You guys are all so original in your thinking. That is why I enjoy reading this thread so much.

Scrat - so on your testing, are you using the cheese grater to make the granules of BP? How dry is your wadd of BP clay getting before you use the cheese grater? Are you sure your final powder is dry enough?

scrat
April 13, 2008, 01:42 PM
Well i think that may be some of the problem but not all of it. yesterday was 90 degrees here. So i left it out in my back porch until the afternoon. it was grated down. i used a cheese grader. then i chopped it up some more as it looked more like 2f than 3f. So im pretty sure it was dry. Im going to try out the remaining of the 2 batches i have left tomorrow. That will be 3 days. As far as how dry it was when i grated it. i would say not that dry as if you pushed your finger in it wet spot would come out. i Put down a coffe filter and put the powder on top of it. Found that the coffee filter will quickly absorb the moisture. it just seemed like a huge difference between goex and mine. the goex burnt fast very fast. Just a big pof. mine was more of a poooof. you could not count to 1 with 1/2 a teaspoon of goex. mine you could count to 2 almost 3

JCT
April 13, 2008, 03:28 PM
Scrat, I think that's about as good as it gets with a mortar and pestle. A properly charged ball mill really makes a huge difference. A chunk of my powder out of the mill displaces all the air around it. It's extremely fast and hot BP. Noticeably faster than even GOEX.

scalper
April 13, 2008, 03:55 PM
Being the impatient man that I am, I had tried using a mortar and pestle too. I just mashed and mashed the ingredients till I had a really super duper fine powder. Heck, I thought it looked like a 10Fg powder, it was so fine. :D

When I tested the fine powder it burnt really fast. After asking many on this board on a thread about using 4Fg powder in a gun, I decided it would not be a very prudent substance to put in my gun. I haven't done anything with my 10Fg yet, but I suppose the next step is to make my little clay ball and get the cheese strainer out. (BTW-It would sure be nice to buy strainer with various size holes that would stack and that would sort out the powder into various sizes. I have seen these, but don't know where to buy it.)

So hang in their scrat and keep pluggin away. I know the ingredients will work, it is just a matter of slowing the burn rate down a tad by creating larger granules. Maybe the stuff wasn't dry enough or maybe the granules too big, but keep trying cause will get the right mix hammered out.

Scrat, maybe you should try creating the raw powder that I did and then do a test burn. That might at least verify that the ingredients are good enough.

Anyone else have any 'foolproof' ways to get the right size granules? I am targeting 3Fg, but anything that gets me close will work. Any better suggestions than cheese graters? What about these tray sortin thingies that I mentioned, anyone have a clue where to get them?

Oh, yeah, and my favorite 'grain-based' BP recipe:
75 grains Saltpeter
15 grains Charcoal
10 grains Sulfur

I guess the stuff I created is called 'meal powder'? Supposedly, it burns uncontrolled, which I can verify does work! For sure!

I just read this on the muskateer.ch site and thought it was pertinent.

So, scrat, I would suggest the idea again of testing some of your 'meal powder'. Don't use water or any other solvent. Just mix up the ingredients really well and super fine. Test it. Then we will know if your ingredients are good enough to go to the next step.

Lets see now, screens. Walmart, two three drawer plastic stack boxes. Junk store, frying pan splatter guards, several mesh sizes. Back to Walmart craft dept. Plastic mesh used for embroidery, comes in diferent mesh sizes.

Cut the bottoms out of all but one drawer and cut the tops out of the support frames. Cut the bottom out of one frame. Fasten the whole operation to some scrap plywood and hold together with bungee cords (Dollar Store).

Fasten an orbital sander to the plywood next to the stack drawers. Pour the powder from the broken cake in the top.

Next and most important step. Put the whole kit and kaboodle inside a large clear plastic trash bag and secure the open end around the drawers and board. LEAVE THE SANDER OUTSIDE THE BAG. If it's not obvious by now please know that the motor in the sander can make electric sparks. The sparks will set off the fine dust and then the whole shebang goes BANG:D:D

Turn on the sander and watch the powder sort its self out.

The top box holds the very large chunks and obviously the bottom catches all the very fine grains and LOTS of dust. The dust is simply reintroduced to the next batch and re-pressed.

I made some really fancy wood screen boxes that are air tight just for fun.

The main point is that screens don't have to be expensive. I don't try to match the grain size of commercial powder but rather get a variety of sizes that I can duplicate in a consistent manner.

i changed the formula then made it the dangerous way.

150 grams kno3
20 grams charcoal
10 grams sulfur

Put a bottle of rubbing alcohal in the freezer.

Grinded knox to a fine powder with mortal pestle. then put in cup. put charcoal and sulfur in mortal and blended them to a very fine mixed powder.

Got out the pan turned on the overhead fan. Put the stove on medium heat. Poured in 3/4 cup of water. added the Knox then stired it until it was completely dissolved. Then slowly added the charcoal sulfur mix. then started mixing it and mixing it. as the water started to evaporate and filter in the mix. i lowered the heat. At first i did not like the look to well so i added some more water to keep it wet until i felt it was really mixed. Then i added some alcohal to the mix under a low low flame and kept stiring. as the water evaporated i turned off the stove added some more alcoahal. Then stired it up some more. By this time it was really thick and pasty. So i gathered it all up. Put out some news papers. put the big hot ball on the paper. took out the cheese grater. Then grated it all up. At first it looked more like 2f. So i took out a long fine knife and slowly went over all of it to make sure it looked like 2ff. then i had it spread out pretty big. Left it that way for about an hour. Then put it all in a cleaned up Plastic coffee container. Then put the lid on it. Yesterday after about 2 hours. i could tell the stuff was going to be powerfull as you could really smell the alcohal and powder.

Today when i lit it. The stuff was strong very strong. Good strong smoke too. Just like Goex, maybe even better. I want to try this again with some willow charcoal. Also want to know what i can do to make it better add more knox or more charcoal.

I think the only problems in adjusting the ratio is that the KNO3 is the oxidizer, the Charcoal is the fuel. You can use more KNO3, then the fuel is burnt up faster, but you have less gases since there's less fuel. In a revolver, that might be ok. In a rifle I'd think you'd want a more gradual pressure build and slower powder is ok.
75% 15% 10% works so good I never saw a need to try anything else in shooting. I do other ratios for BP rockets though.
I just came across a bunch of swamp alder, I'll be making a batch with it to compare to willow. It should be as good, possibly better. The hottest BP I've ever seen was when I made a batch using balsa wood. It was lighting fast and bright too ( hot ) . That might be the ideal BP, but Balsa is so light it's tough to mill.

for making bp i had a coffee grinder that worked very well to mill the kno3 in but only a mortar an pestle for mixing all ingredients together..... but yes i tried a very VERY small batch of coal based powder, it did not work very great but it would move a bullet with deadly force no doubt. i think charcoal works better because it has so many pores that the actual surface area is really very huge... i think united nuclear stated something about this on there site.but coal is very hard(hard enough to break my coffee grinder blades sadly:() and smooth so the sulphur and kno3 would have a problem reacting with this..... little bit more info, you dont need coal or charcoal you can use confectioners sugar, regular sugar for smoke bombs lol, graphite or any other readily avilable source of carbon, maybe powdered milk or creamer too:scrutiny:? sugar is messy an makes things get wet too fast and i think charcoal is pretty easy to make, put some willow or grape vine in a coffee can with lots of tin foil on top and a match stick sized hole, an chuck it in the fire till smoke stops coming out the little hole... umm... dont take off the tin foil till it cools off either or it will catch on fire an burn up lol:D

There is a recipe and instructions in Blood Meridian by Cormac McCarthy.

Okay, I'm making progress. I have my digital scale and a precision Ohaus balance scale, stump remover ($5 at Lowe's), 90% sulfur ($7 at the local ACE Hardware), a bag of ordinary Kingsford charcoal, a bag of cedar chips, a box of thoroughly dried pine board scraps, a bag of confectioner's sugar, and a box of coal. There's no coal here, but a 'net buddy said he would send me some. He sent 32 pounds of it. I guess when you're heating with it, "a little bit of coal" is a somewhat larger amount than when experimenting with gunpowder... I also have a homemade ball mill and a couple of cans of commercial black powder to use for comparison testing. I still have to acquire a gun to use for experimentation; I don't want to use any of the ones currently own.

The plan is to build a spreadsheet of powder mixtures and preparation types, then load a small batch of each to get a quickie idea of smoke and fouling, then refine the cleaner ones down by bullet weight, primer type, etc. At this time I'm more interested in getting a clean burn than muzzle velocity.

I'll be testing all the usual BP formulations, including the sulfurless ones, coal, different charcoals, sucrose, fructose, corn syrup, molasses, etc. I've probably been reading way too much rocket motor stuff, but the idea of simply casting cylindrical propellant charges, dropping them into the cases, and seating the bullets appeals to me more than making powder.

I don't know what formula or instructions that you're following, but here's information about how to make charcoal for black power:

And from the same source, here's how to make home made black powder:

I hadn't seen that one, but it's the same basic process I've seen elsewhere. However, it's one of the very few that doesn't start with "first you get a 55 gallon drum..."

ok first of all i would scrap the materials and start all over. been there done that. you need black willow charcoal powder. re read what was in the pages a few back. a good source for NOX potasium nitrate is ebay or amazon. same with sulfur. you need to get pure ingrediants. charcoal briquetes wont work you will make black powder that will fizzle but not be good for anything else. re read everything. pure ingrediants and a ball rotary tumbler are the best to use. there are several methods of making it some work better than ever and some dont.

Something I might be able to add to this...

Here's some information you may find useful or interesting. I suggest you actually buy the Von Maltitz and Sponenburgh books as these are living authors who deserve something for their efforts. If you're broke or don't care, you can download these from the net for free- Tenney Davis has passed on (and is out of copyright), the US Gov't. will be happy you bothered to download (and follow!) the federal explosives laws.

Look at the history of the DuPont family. Notice all the dead (mangement level!) people, and blown up mills?

http://www.historypin.com/attach/uid32851/tours/view/id/945/title/Explosions%20in%20the%20DuPont%20Company%20Black%20Powder%20Yards

Google the names of any black powder maker, historical or modern along with "explosion", "deaths", etc. You will find plenty.

After Du Pont sold the last powder mill in the USA to GOEX, there were a series of problems. A lot of you know about the GOEX production moving out of PA, then moving again- The meaty part starts at page 10.

In my research regarding powder mills in the Texas hillcountry and Bexar that supplied the Confederacy, it is interesting to note that they made powder using cedar charcoal, nitre from bat guano, and sulfur imported from Mexico, kinda like John Glanton and the Judge did in "Blood Meridian" in the cave they were hiding in.

I am a novice and have nothing to offer at this point but I find this all very enlightening. I want to extend thanks to those whose wisdom I will pilfer as often as possible.
