RCBS UNIFLOW aggrivation-any ideas?

[H&R Glock]

I have the Uniflow powder measure and the rigid bench mounted stand. The measure threads to the stand with about 10-12 turns of the measure. Every time you empty the measure, you have to un-screw it,l dump it, and then thread it back for the next powder, etc.
There was never a better use for the Lee "Lock-N-Load" mount than in the RCBS powder measure. Unfortunately I don't believe that the needed accessory is available for this mission.
Has anyone mounted their bench mount to a piece if 1/4" plywood and used a speed clamp to hold the base down to the workbench? The clamp I speak of has one handle and is permanently fastened to the work surface. One lever throws over to clamp the desired work piece. I don't know the proper name for the clamp, but hope someone else has become frustrated enough to build something that makes emptying the powder measure quicker. I will Ebay "clamps" and see if what I am looking for is available. Your comments are invited. Thanks
Just got back from shopping at Ebay.

Here is the clamp I was thinking of. They call it a toggle clamp. Cheap so I ordered two. I will take picture of completed project when I get it installed.

I have the uniflow and I use the basic flat steel holder where the uniflow screws in one end of the piece that's about 5" long. I then clamp the other end of the holder to a shelf above my bench surface using a small C-clamp. So, it's like the measure is screwed into the outer end of a diving board. It works really well for me, keeping the measure off the bench surface and at just a perfect height for using a loading block under it. When I need to empty it, I just release the C-clamp and tip the measure and holder combo to return the powder to the container.

At times, re-clamping it to the shelf is awkward since I'm holding the the measure/holder combo while also holding the clamp and tightening it. Another hand would make it so much easier. I've been thinking about searching for some other clamp style that could make it handier. I may have to head on over to the hardware store and take a look at these clamps.

I had that problem till I found this

[wild willy]

I did this when Hornady first made their Lock and Load

I use the Redding Double "C" clamp.

Works perfectly for what you are trying to accomplish.

10-12 turns??? I turn my Uniflow into the stand about 3-4 turns at the most and then tighten the lock nut.

For some of my case charging, I use a Hornady powder stand that uses the L-N-L bushings. Similar concept to the Lee Breech Lock. I use it mostly for setting up the powder measure that I will be using on the progressive press, then transfer the measure to the press. But, I do some case charging with the stand when I am using a single stage press.

Also, I have some powder measure stands that are through drilled (not threaded) with a 7/8" hole. I slip the powder measure into the hole and use a lock ring to snug it in place. Actually, two rings, one above the stand and one below. You still have to spin off something but a nut is easier and quicker than spinning the whole measure. A good place to use Lee o-ring lock rings that have been replaced on reloading dies.

You can always throw maximum charges till its empty, per RCBS instruction. But may take a while if you fill the measure. I would put a funnel in the powder unit and let it act as a baffel. But will all the powder be removed? I dont have one.

 

[John3921]

My RCBS stand is not threaded. The Uniflow drops through the stand with a 7/8 x 14 jamb nut above and below the flange on the stand. All you have to do is spin off the lower jamb nut and the measure lifts out. I've looked at installing a LNL bushing adaptor but I'm not sure there is enough meat on the stand to accommodate the larger threads (1-1/4 x 12)

One of the reasons I like my Hornady PM. The inserts can be removed and replaced. Take out insert, install drain insert, drain. Or just twist it out of the bayonet mount and tip it over.

I got an idea for you. Take a hacksaw and saw off that long section of threads. Then only a few turns to take it off the stand.

 

[H&R Glock]

Binrat- I shouldda' started out with the flat plate like you have, then I wouldn't have had this problem.

As you can see I have the high fixed mount and never got too mad at the design till lately.(screwing and unscrewing the entire measure is a pain!) :banghead:
X-ring and Wild Willy, you have designs that I don't fully understand, but figure you have something like a press fit or a "slide through rig" with clip or nut fastener on the bottom.
I wish something like that was available when I bought my RCBS Kit back in 1980.(maybe it was?)
It looks like I can have my stand drilled out and then use a nut from the bottom or continue on and build my toggle clamp hold down(which I will do as I have ordered the clamp) and keep my powder stand in original factory condition.
Thank you for pointing out these, new to me, solutions to an old problem.

This what I used with a 1 1/4-12 nut http://www.midwayusa.com/product/858110/hornady-lock-n-load-press-and-die-conversion-bushing-kit You just screw the conversion bushing in the nut the die bushing on your measure

 

[FROGO207]

I really like the Ideal/Lyman 55 for this. The small clamp at the rear is easy to deal with IMHO. I also have a Pacific measure that I use two lock nuts on the thin non threaded mount. One above and one below the mount. The lower one is only on about 1.5 turns and never comes loose.

 

[RKRCPA]

You could switch to the Redding powder measure stand. It is not threaded and allows you to remove the measure from the stand by simply removing the lockring at the bottom.

I bought a powder measure stand, but have not used it. I use my lee single stage with a bushing. 1/ turn and its out, I have a lee classic cast turret, a lee aluminum single stage, a Dillon SDB and a rcbs sizer on the bench. I will never get rid of the single stage, always finding a use for it.

 

[gfpd707]

I just bought a rcbs stand and it is not threaded. Just drop the powder measure in and tighten jam nut.

 

[grandpawj]

Here is my solution, either pick up the whole thing and dump or loosen knob, slide off shaft, dump and return.

 

[H&R Glock]

Wow! everyone in the world has had the same problem and you guys/gals are all attacking it in different ways...... including me. I thought I was the only one to get mad at the system.
WILD WILLY- I am convinced that your solution with the #858110 converter bushings is the neatest, low cost, and fast fix for this engineering problem.
RCBS shoudda' thought of this when they designed the cast stand.
All of you have helped me greatly and I appreciate your ideas, pictures, feedback and comments. Long live home engineering!!

I have my powder measure stand bolted to a roughly 3 inch by 8 inch piece of plywood that I clamp to the edge of my reloading bench using a C-clamp.

My reloading bench is in my garage. Everything on it is attached with C-clamps or bolts secured by wing nuts so that when I need to do painting or woodworking in the garage, I can clear everything off the bench and protect it from overspray or sawdust.

 

[fireman 9731]

I just throw big charges until its empty... But the Lock-n-load bushings look like a great idea.

 

[H&R Glock]

Hey Fireman- I guess that's better than throwing a match in and burning the powder out!
I have ordered the bushing kit from Mr. Potterfield (Midway). It should be here by Saturday. My toggle clamps may not arrive till May 6 from the Ebay deal. Go figure.
The only worry that I have with the bushing kit is the length of the drop tube. If the bushings don't work out, I can still rebuild with the clamps. They are faster than C-clamps, but have to be screwed down permanently.

Thanks all for your clever engineering!

 

[carbine85]

I just reload until I'm out of powder. Problem solved

 

[John3921]

Curious if your stand is already tapped for 1-1/4 x 12 to accept the bushing? If not, how are you planning on tapping it?

My RCBS stand is 1-1/2" OD where the PM sits. If I were to tap it for the bushing I'd only have about 1/8" of aluminum casting left.

 

[Gravedigger56]

I had the same problem with my turrets for my RCBS press, threaded and a pain to change out powders/calibers then re-calibrate etc.. I eventually ended up purchasing a separate Uniflow for each one of my turrets dedicated to each caliber. Since then I have switched to a Chargemaster and never use the powder measures much any more.
