You can see the angle I cut into a 3/4" piece of plywood. I cut a place for my arm to rest also. Actually with the original top, I added a piece of board to rest my elbow on first, then just grabbed the piece of plywood and started marking.
I really like the Caldwell Stable Table. More so now that the top is more like I like it.
First pic is the addition of the elbow rest...
