Power case prep
I saw a video on youtube where a guy had adapted the Lee case trimmer cutter to fit on an RCBS case prep center. All he did was drill and tap it so it would fit on one of the stations. He put the case holder in a multibit screwdriver and voila, a motorized case trimmer. The best part was, he trimmed the brass, then inside and outside chamfer without ever taking the case out of the holder (the chamfer tools were on two of the other stations).
Then take the case off the holder, turn it around and clean out the primer pocket, on another station, and you're done.
I should have a Lee tool modified early next week to try, and I'll let you know how it works. On youtube the guy had it down to about 10 seconds per case. Really slick.
