Re: AICS and Jewel triggers
I fired up my Smithy, which is a combo lathe and mill. I haven't used it much. Nothing like learning on a $1000 stock. I was able to do a good job of opening up my 2.0 and one of my 1.0s for the Jewell triggers.
I even opened the lug slot on the 2.0 for a 7 twist 223 AI while I was at it. That was a little tricky, mainly in getting everything parallel. The big deal seems to be not to let the cutter touch the back of the lug slot. The oversize lug was also deeper than the factory lug so I had to deepen the slot. I cheated and used a file to finish the bottom back of the slot after getting real close with the cutter.
