I tend to do bulk batches of brass prep for reloading, which means hours of deburring, chamferring, primer pocket cleaning & uniforming, and flash hole deburring. My hands were really not enjoying the drudgery of this brass prep, so I devised a quicker/simpler/easier way!!!
My hand killing set-up included a Lyman Case Prep tool and Lyman Flash Hole Deburring tool.
They're great tools and work really well, but my hands start to cramp up just looking at them...
I have a Forster lathe set-up for trimming and neck turning, and it has the power adapter for a cordless drill or screwdriver, and I got to thinking.
All these tools thread into some kind of handle, and all just happen to have the same thread pitch (8-32), hmmm...
I picked up a package of 8-32 nuts and found an old 9mm nut driver to sacrifice for the project.
The nuts are actually 11/32", but I figured that I'd miss the 9mm nut driver less.
A little bit of JB Weld and it was coming together.
It took a little bit of wrangling to get the nuts in the driver with the threads lined up and straight.
I used 3 nuts in the driver to fill the space and give the accessories a solid attachment.
Now that it's done, the hand cramping chore of brass prep has been reduced by at least 75%.
Gotta be careful when chamfering/deburring, as it's easy to take off too much material.
All this for under $10, as I already had the cordless screwdriver.
It works awesome, is way less painful on the hands, and reduces a LOT of the drudgery of brass prep!!!
