The board that actually touches the gear leg is the only board that must be fairly long.
(that is the one that runs vertically in the picture)

If it happens to be something like 12 feet long, you do not need a weight at the end.
(the end AWAY from the airplane)

If you don't have a board that long, you need an old battery or something heavy to
sit on the end and a couple of small blocks under each end of the weight.

Be careful; the weight might fall off.
