Automating Depriming

[Rich22]

So I have a weird one here and need the brilliance of the group. I need to automate the depriming step in brass processing. I like to deprime before running through the Stainless and handling each piece just eats up time, so I want to figure out a way to deprime them automatedly. I have or can make another case feeder without a problem but short of automating a 1050, I am at a loss on how to do it. If there is a way to do it kind of like push through sizing then I can see that being a smooth process that will just need a feeder/ a single stage and motor setup like an automated push through sizer (which is my next project anyways). I know we have some of the best minds and machinists in the shooting world. Anyone have an idea on how to start this concept I would love to hear it

Thank you

Rich

This is is the way I do it.

But I suppose it would take more force to push through size a case than push the primer out so something like this with a decap pin in the center of the arbor that pushes the case through the die might work.



FWIW I never run dirty brass into any size die.

[OS OK]

A separate self indexing turret with a case feeder and a universal decapper? Then on into the cleanup process?

I bet your garage sounds like a mini-factory all the time.

OH...just found this on 'automated depriming'...

That is exactly the next project right there. With depriming though, assume the push through size die in your machine was a decap die the issue then really is getting the case back out of the die. It would be easy enough to make a hollow ram to push the case down and that would let the decap pin do its job but then the case being extracted is where the idea becomes an issue. Only thing I can think of, and no idea how to make it feasible, is for the entire die then to do a rotation which would allow the case to drop out by gravity.

In all reality a 1050 solves so many problems it would probably be smarter for me to just to buy one, automate it and be done with it. Just trying to avoid that cash outlay.

Lee loadmaster with case feeder.

If I were going about it that way I would machine a custom arbor that locates inside the case and once the decap pin pushes the primer out, after the arbor has already located inside the case, it can then continue further and bottom out on the inside of the case and push it through the die sizing the case as well.

Sizing really wouldn't save me any time but I get what you are saying, no clue how to actually do it but I see the idea.

[packnrat]

sizing can be done on the press. but de-glocking and popping the primers thinking here.

Wouldn't you imagine that would lengthen the case making the bulge flow forward towards the case mouth...better put a case trimmer in the mix now...then chamfer to boot?

[Ehaver]

get a cheap progressive that indexes and put a motor on it. every once and a while a lee progressive will show up in the for sale section or look on ebay.

No, it's the same concept as this machine http://www.magmaengineering.com/case...ss-case-sizer/ except with a decapping pin in the arbor that pushes the case through the die. The run them through and then just size with a regular die and that is all that is needed.

I was thinking the fellas here were trying to figure a way to make a home made apparatus to do this, didn't consider you were talking of buying a ready made one.

I was just pointing out that that that one does the same thing the homade machine I posted in #3 is doing, although quite a bit slower and about $5900 cheaper.

Wow, I start a thread about removing primers being automated and we get all the way to push through case sizing which I do not believe I have even ever seen done. Any ideas to get this done without having a machine shop?

[Garyshome]

I need one of these too!
Looks like some sort of progressive press with a case feeder, simple nothing to it. I'll get right on it tomorrow.

I thought you were familiar with the process since you mentioned it in your first post.

If there is a way to do it kind of like push through sizing then I can see that being a smooth process that will just need a feeder/ a single stage and motor setup like an automated push through sizer (which is my next project anyways).

Decapping with a push through sizer would simply be a easier device to build than one where you have to push/pull the case into and out of a die and load/unload it from a shell holder/plate. If you can make the rest I am pretty sure you can drill a hole centered in the arbor that pushes the case through and install a decapping pin. You would actually need to make your own arbor anyway so the case is pushed through the die base first (like the case master) as Lee intends the arbor they send to shove them through mouth first.



You would want the arbor (actually decapping pin on the tip of the arbor until the primer gets pushed out) to go inside the case and push it through the die like the case master and case master Jr. do.




Short of that the only two ways I can think of doing it would be to pay someone to build it for you or buy something already on the market.

Mark 7 has a 650 drive for $1900, you would still need a case fed 650 of course.

Or the Ponsness/Warren 650 drive for $950 again without the press.

Would be the least expensive way if you can't build it yourself.
