How about double sided sticky tape? You could tape a little strip of wood or plastic to the floor and let the pedal run up to it. At first I thought constuction adhesive, but that might be a little hard to remove if you needed to move the little stop strip!! Or the adhesive velcro..stick one side to the floor and the other to the pedal?? If you're really a lead foot, stick several pieces down :lol: :lol:
If your table is against the wall, put a piece of plywood or even a book against the wall but lying on the floor to run the front edge of your pedal up to.
