Okay, this weekend the spotlight shines on the initial receiver work. I did the basic fitting for the trunnion and stock tang. The receiver blank is a Robert Ibe 0.050" battle blank.
In this pic, I have the rails roughed and the length cut as for a normal AK receiver. The line on the top of the template is my cut line for shortening the receiver. I removed 0.800" from the bolt/carrier, so that amount must come off the receiver to get the parts to line up with the hammer. I touched off the front of the blank and then cranked the table 0.800" to check my mark. Everything lined up correctly, so I made the cut. I have the stock tang slid inside the receiver to keep the sides from flexing in the vise.
This pic shows the shortened .45 receiver compared to a standard 7.62 OOW receiver. The notches for the top cover are just visible at the back.
I need to do some welding on the bottom of the trunnion before it can be riveted in. The rails need to be trimmed to width, but I think I'll do that after the trunnion and stock tang are riveted and the center support & lower rails are installed.
I'm getting more and more excited about this project as things start coming together!!! :woo:
