I see one huge flaw in that design:

The stop has to be completely unthreaded and removed to accommodate a board
longer than the sled is wide. An F-clamp with a block arguably less fuss.

Maybe if the back corner of the stop block were radiused so that it could
rotate up and out of the way of 1-by stock it would be better.

This one from the WoodSmithShop is simple and neat.
