Redneck Brass Prep Center

This is a work in progress, low budget brass prep station. I hope to approximate a Frankford Arsenal Brass Prep Center ($160) at a lower cost. I already have a World’s Finest Trimmer, so I do not need that functionality of the Frankford Arsenal unit.

My primary concern is quick neck brushing, primer pocket cleaning, chamfering and deburring. My preferred primer crimp remover is the RCBS Primer Pocket Swager that does a beautiful job of removing primer crimps without removing metal like the reamer shown. It is comprised of a round electrical box cover, four 8-32 machine screws and four 8-32 sleeve nuts to accept standard 8-32 case prep accessories.

I need to determine how to make a thread adapter coupling to attach a 1/2″ drill chuck to my wet tumbler driven by a windshield wiper motor. I know HOW I want to do it, I just need to decide how to do it (precisely) without a lathe.
