Anyone ever use keystock to make sledrails for a tablesaw sled or similar? I have one small piece (about 2" long) that is a perfect fit for the slots on my tablesaw. I was considering getting a couple of sticks to cut and use on a heavy duty frame miter sled. I have worked with it some in the past and think it might work well, I just don't have alot of experience with plywood. I don't know how much movement it would have. The keystock is a perfect fit, so there is very little room for movement in the base of the sled. Any thoughts?
