Here you go. The skis are simple to make. I used 1/16 lexan (3" x 14" ) for the base and 1/4" thick for the upright. Drill a hole for the axle to go through and drill another hole to put a stopper (bolt). Then use two elastics to pull the ski up. It should only lift a small amount to ensure the tip does not dig in. All three skis are the same.
