This is probably to be seen more of an inspiration than a true guide, since the materials may vary a lot.
However, this is a really simple project that converts two pieces of "rubbish" in to something fun. You could build this in a few hours or days depending on how much energy you want to put in to it...
Sorry for the poor quality of the photos, whey where taken using a mobil phone.
*(angle iron or similar)
Only your everyday tools like:
*Saw (fine tooth for the steel edges)
*Drill and drill bits
If you dont have an old snowboard lying around, you could of course use a pair of old skis, but miss out on the awsome off pist powder performance =)
