The process of making a cylinder!

[Third_Rail]

We've decided to make a series of photos, showing steps from raw material to finished product in making a cylinder.


Here's photo #1.

That's a full $600 worth of raw material - our cost. This is the highest quality maraging steel money can purchase, which is why it's the steel we use. One section of this steel will become a .58 caliber cylinder.


More to come soon.

So it's like rebar right?

What's the diameter of the stock?

 

[Third_Rail]

2.25" +.002, -.000, I believe. Certain on the 2.25" diameter, not certain on the manufacturer's tolerance.


And yeah, it's just like big rebar. Go try it with rebar!

 

[RyanM]

Expensive stuff. For that price, I'm guessing the tolerances are a wee bit tighter than that. $104 per foot junk (17-4 stainless, annealed centerless ground) has +/-0.003" tolerances. So 3 times as much variation, for 1/6th the price.

 

[Third_Rail]

Expensive stuff.

Quality of materials and workmanship is absolutely our top priority.



Re: tolerances, like I said, I'm not certain. I'll ask later today....


Thinking about it, I may have just assumed that it was +.002 -.000; it may very well be that the tolerance is in tenths of thous.

 

[Manyirons]

Its +- .015! Precision comes AFTER tha MANN does his business. Aint made for shafting, made for turning INTO parts.

And yep! Tha piece that got cut yesterday from this is about 100.00 and tha MANN said; when its YOUR money, you can cut it, not before! I DO gets ta carry it! Hell, tha raw material here is worth morein my house! So tha cylinder AFORE its done is 100.00 worth of steel. And ya wonder why some things cost so much?

Somethin like eighteen varieties of steels here, from AIRMETS ta 465 Carpenter stainless.ALL of em priced like gold. I get ta look at tha specs and theys all strong strong strong!

Up for his 3am shot!

Maraging steel, eh?

Known for excellent machining qualities (the Soviets used it in applications for their military and space programs where they didn't need the ultimate strength, but did need the machineability), but with hardly any carbon in the mix, it still needs a good old-fashioned heat-treat, or I'd wager you aren't going to be making Colt Walker cylinders outta the stuff.

It's also a wonderful material for constructing gas centrifuges when enriching Uranium Hexaflouride, modifying the U235/U238 ratio for nuclear weapons or submarine fuel. Be careful how much of the stuff you order and buy, you may get some unwanted attention.

 

[4v50 Gary]

Wow! .58 caliber revolver to boot? Geez. That's big bore and superior steel.

 

[Third_Rail]

Gewehr98 - I don't believe it's quite the same material as the steel the USSR was using. I would post more details, but I don't think giving away business secrets to be wise!


4v50 Gary - Jule, the smith, is a wild man when it comes to smokepoles. A .50 caliber ROA is a regular carry piece for him, I gather.

 

[Gewehr98]

Oh, trust me, it was indeed a popular alloy for them.

- I don't believe it's quite the same material as the steel the USSR was using.

Hypothetically speaking, there were aircrews tasked to retrieve post-impact fragments of Soviet MIRVs in the Pacific Broad Ocean Area in the late 1980s and early 1990s, then once back at home drome they got to see the alloys come off the subsequent molecular analysis like a who's who of metallurgy. Neat stuff, and now that a certain crew dawg's retired from active duty I wish I had my own ion microprobe and X-ray diffractometer. (I used the latter once to verify Oregon Trail Lazer Cast bullets did indeed have silver in them, but only in trace amounts)

 

[Third_Rail]

I do stand corrected!


That's why I love this place, never stop learning...

 

[Manyirons]

So Was Scandium Alloys!

Tha MANN reminds that simply bein soviets didnt make them stupid, jus misguided.

We can thank them fer tha scandium alloys and likely much more we jus dont wanna!

And yep, heat treated ta be sure! like 300,000 psi worth! Ya see, them cylinder walls aint whatcha might call THICK, and tha MANN believes in redundancy! In particular when it come ta safety margins.

 

[Gewehr98]

I hear ya, Manyirons!

Every time I look at how thin the cylinder walls are on my S&W 696 L-Frame .44 Special I thank Gawd for proper metallurgy and heat treatment!

 

[Third_Rail]

Here's the cylinder cut, center drilled, indexed, and it's ready for boring!

metal strength question

Has it ever been determined how much strength a cartridge adds to a cylinder chamber? 10%, 40%, etc. In a cap & ball, the powder explodes directly in the chamber; in a cartridge revolver, it explodes in the casing which is inside the chamber.
I know, one of those questions from a metal/ballistically challenged shooter...

 

[Manyirons]

Answer! Less than 1.0%. Case wall bein thin have one job, maintain tha integrety o tha assembly (I paraphrase my mentor here) otherwise, all tha actual STRENGTH is in tha cartridge case HEAD and area there. Prevents gas from escapin. A brass case .015 or so thick aint strong!

Try findin a powder charge that WONT burst tha case ifin it were outta tha gun and propellin tha slug even a little ways, dont think you can.

Less talk. More Pictures!

Chop chop

 

[Third_Rail]

I've been out of state for a bit - I should be getting more pictures soon.

No - don't hit me Thom, I am only joking but more pics would be nice. Ouch, now that was uncalled for TR

The MANN notwithstanding, I don't believe you guys with the 600 bucks for half a foot of your "supersteel".

It is not a supersteel, it is available to anyone. If you have a machine that csn do what the MANN can do, a good lathe will do, with a decent index table, and a few cutters, a cyl can be made.

I don't degrade the MANN, I still don't like the way you 2 are trying to push his product. You sound like Ron Popiel, the "Vegematic" guy, selling trash.

If Jule, pronounced Yuleh, is using you to move his product, no matter how good it is, he is making a big mistake. Hell, I don't know if either of you even SHOOTS BP. You both sound like shills, "Gots to talk to the MANN to answer that."

Man, either learn the product or move on to one that you do know, like Play-Doh.

Cheers,

George

George,


Sorry you feel that way - you don't have to use any of our products, of course.


EDIT: I truly feel that I must add more here.... while remaining civil, do you have any proof or reason why we are lying? $600 isn't exactly out of the ordinary for good 2.25" diameter maraging steel.


Like I said, though, you don't have to use any of our products. If you don't personally believe that they are worth your money, that's just fine with me. They are, however, quite obviously worth your time, as you seem persistant in your unfounded complaints.


To everyone else - another picture is forthcoming.

 

[Manyirons]

George!

Still needin attention are ya? Tha MANN himself talked to ya and yer not enough of a gentleman ta even mention tha point.

As ta yer "complaints" mentioned them this mornin to him. HE suggested that WE stay to tha HIGHROAD, and let YOU keep on your lowroad path by yerself.

An i DONT have tha keyboard ta do it but its more like that little mark over tha E, SOFT not EH.

Forums = information = knowledge

Everyone has the facility to press the 'Report Post' icon if they feel that someone is not playing the game and there are 2 modorators who can act if necessary. I for one have no problems with 'product info' on this site. I can ignore it if I like or I can read it - no one MAKES ME DO IT.

It reminds me of a tale from my home area.
An American (sorry) was walking down the road when he saw a local rolling a grey/green material in his fingers and dropping the resulting ball into a bucket.
"What ya got there pard?" said the yank.
"Learning Pills" said the Yorkshireman.
"How much are they?" asked Hank.
"$4 each" said the local.
So the yank bought 2 and ate one. "Ugh!, they taste just like sheep ****" he exclaimed.
"Tha's learnin" said the Yorkshireman!

Sometimes you have to try things to learn about them; opinions are part of the process and questions add to the knowledge levels but bare rudeness is not worthy of an inquisitive mind.
If you can't be civil then don't be heard.

Duncan!

Said it better than i could! Englishmen always better at this sort of cool wit thing than i am!

More comin soon, tha MANN has been nursin those bad discs in back.
