Showing the first jig that didn't require any milling machines to cut the rails on the 1911 frame. While this jig is really great for aluminum frames, it can (much slower and requiring more labor) cut steel frames as well.
The beauty of this jig is that it allows you to cut the rails as well as drill the holes in the frame. But, it will not accept 2011 frames, and is not all that great for steel frames.
Still, here it is and how you use it.
