I decided to make up a jig for checkering. Mostly for recutting checkering on stocks that are on the receiver. I find that the stock mounted on the receiver is more stable and easier to manipulate. Anyway, I used some scrap aluminum and some oak I had and a small part of an oak table leg.
I made several sets of blocks and have different length screws for holding. All parts made so as not to mar a receiver.
screw holes allow for different receiver shapes, lengths etc.
dont mind the mess on the bench.
