just place the two pieces of wood far enough apart so that the binding fall under and the skis lay flat. put some rubber on the wood and skis will not move
i made a table for $0 using wood i already had and some eyeballing. the thing is rickety and the two platforms aren't completely flat but it's close enough. i stapled part of an old blanket to the tops to prevent the skis from sliding and it works well enough.
