The only factory parts are the G2 refill, clip, and spring. I made the blank out of fiberglass resin and testors paint cast in a PVC tube because that's what I had. It was cheaper than buying blanks to practice on, and there was about 3 explosions. The worst part was when one died it was because I was doing something that I was doing that was wrong. The top ring and the nose are 6063 aluminum. I used a 9x1 mm, 3/8 NF, and 7/16 NF tap and die. The cap is about 14mm wide and the body about 12mm. It is just slightly longer than a normal capped pen. I left a little more materiel on the back because the back ring is threaded on and epoxied to keep it there. Wasn't sure how strong it would be. Next time I'll make the body bigger because when you thread a 9mm hole inside a 11.1mm hole there isn't much left. The 2 aluminum rods with threaded inserts on them were used for final polishing, the whole tape it and put it back in wasn't working for me. I could feel the spot where the polished ends met. I also had to make a collet to go in my collet. Please give me your honest opinions because I can't improve without your help. And if you say something mean I promise not to sneek onto your house at night and lick the inside of your coffee cup.
