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 =)
Step 1: Back to basics
Strip the bicycle from its wheels, mud guards, shifters etc. till all that remains is the bare frame with the saddle, handle bars and the forks still attached.
If you have the tools required to remove the chainrings(s) and the crank arms, use them!
If not, follow these simple steps:
1) Turn the bike up side down
2) Grab your largest hammer
3) Smash the chainrings as much as possible out of the way so that its no obstructing anything.
You could probably use the fine tooth saw, but that would have taken a whole lot longer.=)
Remove the bindings from the snowboard and remove the straps from the bindings.
Step 2: Cut the snowboard in half
Use some kind of ruler to draw a straight line at about 2/3 of the boards lenght. Its not really crucial.
Use the fine teeth saw to cut the steel edges, make sure you get all of them, they buried like 15 mm in to the board. Then use a regular saw to cut the snowboard in half, its made out of wood and plexiglass so it shoundt be a problem.
