I made some of these 4 years ago, but I gave them away as gifts.
I decided to make 1 for myself, so I ordered the kit. I did not order bushings because I should have them since I made some earlier.
I glued up the camo blank, cut the plastic on the ends down to the 3/8" brass tube, and was ready to go to the lathe.
I got to studying the pen kit I ordered, which was PK50RBX 50 cal rollerball flip kit. I got out the PK50CALBU bushings, and they were not the right bushings.
Seems I should have ordered kit #PK50CAL.............which is a standard type pen............and takes the PK50CALBU bushing kit.
The kit I ordered is a flip kit, you pull out the pen assembly from the shell, then write with it.
So, I ordered the right bushing set #PK50RBU.
Guess I will wait for the right bushing set.
I ended up turning the speed up on my 1939 Montgomery Wards wood lathe from low to medium, when turning the white/black camo blank.
I had doubts how good this pen would work, in terms of removing the writing part from the 50 caliber shell, but it works pretty well.
