Duca: you were asking about those 2 wing nuts on the version from the store. Theres 1 behind that is supposed to lock it into place at various angles up/down. The other wing nut tightens the bolt onto the base that is supposed to lock into place for left/right moves. So when youre depending on it not to move, my experience is it cant hold in place routine filing/rasping torques. Sorry i have no photos to illustrate right now
