I threw this thing together from some scrap wood I had lying around. It holds my foot pedal in an almost vertical position. The construction details should be absolutely obvious. I have not bothered with listing dimensions as nothing is critical.
There is a strong elastic band running around the pedal to keep it in position and keep it from falling forward. The band passes over the pedal just above the pivot point so it has no effect whatsoever on the pedal's action. I also put a small wedge of chair foam under the pedal to avoid any 'scuffing' of the lip of the pedal against the bottom wooden plate. Beyond that there are no mechanical connections at all and the pedal is in no way altered or damaged.
Holding the pedal construction in position is the only issue. I think that the best approach is probably to put some bricks or maybe a cinder block on the back end to hold it in place and keep it from skating away from the foot when in use.
Hope this inspires some of you.
