What a typical question from a PM,need plan to blame when things go wrong!Here is a tip get a plank of nice buckinard lumber ie terpentine take one 4" grinder with chainsaw type wood arbor blade & go nuts.You may need to borrow a real ski off one of the AT crew but as a template!!
Somewhere I have an article in either Schuss or Ski Horizon, the Victorian monthlys from the mid 30's to about 1960 on how to do this. The prefered timber was imported hickory, while the poor mans alternative was domestic Woollybutt (Alpine Ash). The tips were steamed in order to make them more pliable so they could be bent. Anyone who wished to ski steep country then fitted brass or steel edges to the planks with bent ends, which they called skis.
Just before and after the war lots of skis were made at home and all the ski shops advertised the quality of the edges that they stocked. I'm working on a big contract now so I don't have time to dig around looking for the articles. PM me in a months time if you still want it and I should have the time to dig it up.
