I wanted to take a break from building jigs and decided to use my milling machine for something different.
First thing was to fill in the rear trunion hole and grind them down. Then the fun part began... I didn't take any pictures, but the biggest part was getting the dimensions right considering that I was working with a flat not a bent receiver. The angles play a big part on where the holes line up.
Anyway.. here are a couple of pictures of before bending and after bending with my jig. The rivets are just stuck in to line everything up for now. I'm toying with the idea of modifying a bunch of flats and not drilling the trunion holes. Would anybody be interested in that?
