So I'm attempting to figure out how to build the frame for the Skateboard segway and I think I made some serious headway.

My dad (Bob Rutkas, even though he is an evil mac user), has informed me about Bosch aluminum framing and it is AWESOME.  All I need is a band saw and I'm set.

On the flip side, I could go carbon fiber too.  Robot Market Place has some cool stuff that may be usable.  I'm not sure if I'm able to drill into it and construct it with lets say wing nuts.  That is the part that worries me.  But it looks SO damn cool!

Plus the aluminum framing is competitively priced.
