Automated de-primer design?

[Fluxed]

I like to begin the processing of my cases by de-priming, cleaning, then sizing. I do a lot of .45ACPs with a single stage press and a universal de-prime die. I like to keep a good supply of clean and ready to load brass on hand. Its a slow process now.

I'm thinking of an electric motor driven, eccentric cam operated plunger to knock out the primers and maybe a wheel or a linear feed into that operation. Feeding by hand won't be so bad if I don't have to pull a handle and remove the case every time. Maybe a case feeder comes later.

This is just to de-prime, not to re-size - so not a lot of force involved on downstroke, upstroke or case holding. And just for pistol cases - so not a lot of length to the stroke.

I have good manual machine tools and some skills but no design at this point.
Anyone have any ideas or examples to share?

This one deprimes /sizes and swages but you could just deprime, over 4000/ hr

That is nice.
Is that a modified Dillon 1050?
I'm thinking about starting from scratch - a stand alone machine.

[jmorris]

Yes, it's processing 40 in that video.

I still have not finished automating my 45 acp 1050 but it will also cull small primer brass too.

This is that device.

[jmorris]

Although its upside down and doesn't place anything into and eject from the shell holder, this is a single stage that I automated.



I would think it would NOT be a good idea to try and manually feed and eject cases by hand. After you destroy a finger or fingers it will make a 1050 seem cheap.

[Fluxed]

Oh no!
When I say feed it by hand, I mean to put the cases into the feed device. No fingers near the actual de-prime operation. i.e.- with a circular feed wheel I'd place cases a couple places away from the action.

[jmorris]

You would just need a way to have it indexed precisely and have the case held. You would essentially be building your own progressive press, just using one station.

[Fluxed]

That may be why there is no such machine. It does kind of turn into making a progressive press but with only one station.

More comments or ideas welcome.

There was a thread where someone made an easy eject device to put on their single stage. You put a shell in the shell holder, raise the ram and resize/deprime, then lower the ram and the device pushes the shell out of the shell holder into a bin. I think Inline Fabrication makes his own version for sale.

Sorry I don't have the Skills to make or come up with what you need However.
I Love watching Jmorris's Video's of his inventions, Just wish he could mass produce them so I could afford to own a few of them... Great work as usual..

But- but - you're the Weaponologist. You can do it. Really it isn't that hard. Search RCBS case kicker. It can be made out of metal strapping material. Here's a link to the instructions. http://www.rcbs.com/downloads/instru...structions.pdf You're half way there!
