Modified a Tapco flat to work with a Polish Underfolder

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?

Looks great stickerman!! Keep up the good work. Which template did you use for the underfolder? Do you have a link?
Well, I just fitted a Tapco flat for an underfolder without welding the two holes on the rear. The new holes are just underneath the existing ones, therefore no interference at all. Best thing is you can not see the holes when all together. I havent rivited the rear underfolder trunion yet but I think without having to do any modifying to it, it would be easier on a tapco flat. I did all the holes after the receiver was bent. It was a little difficult, but only took me 2 hours with my handy dandy dremel. I will post some pics later this week.
