How thick IS an onionskin on hard maple, board was .2" birdseye, so it took the pointed roundover to .19" and without going into the embarrassing details(next time belt sander as my coarsest 5" was 100G and the holes didn't match),I spent 1.5 hours releasing the little bandits. NOOO I don't have a thickness sander and have never done an onionskin before(Yes Brady I should have researched- AND yes I should have done a trial cut on the edge of the board- and yes I should have surfaced BOTH sides of the .2" panel). Live and ...........I forget the last part.
