I saw this idea on a facebook reloading group.   I thought it had potential.   You start with:

mini motor chuck

If that link on ebay dies you can search for "mini motor chuck"

I am going to use an old PC power supply.   I will start with 12 volts to see if it works, or convert it to a veriable power supply.

The guy who posted it, actually put 3 on a board, but i think i am ok with swapping out the tools, i plan to use it mostly on 223 primer pockets.

Waiting on a slow boat from china now.

Ok I'm in for one!

Let me know how your progress comes along!

Dammit! Making me spend money again! Also this is a tag to see how you set yours up.

I'm interested also.
 
My RCBS prep center runs soooo sloow, I rarely use it.

Hope you plan to increase the speed over what's available OP.

I think the RCBS prep center runs at a good RPM for the job it's intended to do.

What tool would you want to be turning faster? Everything I use on the prep station is a few revolutions and done.

I can definitely see a reason for a better primer pocket reaming device though.

I got mine today and will run it through that momentary on switch sitting on the top.

It runs pretty fast at 12 volts. You might want some sort of variable motor speed control wired in.

Please keep posts on topic, this isn't a thread about Gracy's. Thanks.

Gracey just happens to be in the picture. My motor set up with all attachments that can be inserted into adapter.

Good timing. I'm working on making a DIY prep center right now. I found some small DC motors that come in different RPMs

I'm thinking of one station at 200 RPM (with load) and one at 800 RPM (with load) then a third station with a variable speed control up to maybe 1500 RPM (great speed for crimped primer pockets)

I'll see how those two fixed speeds work first before I add any more stations. Also I don't even know if these motors will work for the task yet but ill have them Monday.

I think all the functions could be sped up to some degree.



I've found 1500 rpm works great for cutting primer pockets

I'm pretty sure that type of motor will need a gear reduction unit to maintain torque at low speeds. If you just drop voltage to slow it down it may not have the power to keep turning under load

What are you using for an adapter?  Did you just drill and tap pieces?

Just ran it down to 6.5 volts and it reamed a crimp, chamfered and deburred.

I will likely run it at a higher speed, but It was nice to know it still worked if I wanted to slow it a bit.
Now I will build some sort of case for it and wire it permanently.

I used a cast aluminium box from a local electronics store. It's about 5" x 8" and 3" deep with a screw on cover. It holds 7 of the little gear reduction motors I'm using.

The motors are 5000 rpm and have a little gear reduction unit on top. I'm using 300 and 500 rpm final drive and they really have a lot of torque.

I like the 300 rpm for chamfering/deburring and 500 works good for the Lee trimmer, primer pocket cutter, flash hole debur

Motor shaft was 1/2 inch, round stock with 1/2 inch hole in it. Two set screws for each side. !/2 inch piece of round stock with 8/32 thread. Everything just screws on. Works great.
