I would like to put a planing stop on the end of one half of a split top workbench - the kind of a stop that is a board attached to end of workbench with a couple of hand-tightened knobs and can be raised 1/2" to act as a wide planing stop. I am hoping for suggestions on attaching this board. My initial idea is to first attach a 8/4 end cap with heavy bolts, and to put a couple of propell nuts in it to receive a knob on a 1/4-20 bolt. It seems unnecessarily complicated. Other suggestions? I am unable to gauge if long term wear would be an issue if I mount the stop directly in end-grain douglas fir.
