Dave Trant posted a link to this Instructables post on making a recurve bow from old skis:
This bow is made from a pair of Fischer downhill skis. It pulls 58# at @ 28″. The riser is made from walnut and pecan and is coated in a satin polyurethane finish. The string is made from paracord with bowlines. This will be replaced by a dacron string when I get the time to make one.
The takedown shown in these photos is a followup to the instructable I wrote earlier this year. I have received many questions asking “just how powerful a bow can you make from skis?”. This takedown bow shoots nearly as fast as my fiberglass/wood laminate recurves. Once I get my hands on a chronograph I will actually provide some numbers. But based on target penetration and my experience I’d have to say that it performs quite comparably.
