Without knowing how much the parts still resemble skis, it's hard for us to know if the skis are being used as a component or a raw material.

My guess is that if they're fiberglass skis, or some other built up kind of thing, then the original skis are not merely a raw material, no matter what you did them.

I sure understand the situation you're in, it's a tough one. The only used non-robot type parts we're playing with now for this years robot are ones that we have a COTS source of replacements for. btdt
