so i'm still waiting for the delrin to show up...
stupid holidays are messing all my plans up, lol.
so since I was board and had nothing else to do with this until the delrin arrives, I decided to make a tap for the bolt guide threads. BEHOLD....a 1 1/4-28 tap made from O1 tool steel.
it does have a tiny lead-in fr the threads, but not much. I also made the front section in such a manner that it should align itself axially with the bore.
