The following items are very vague with regard to modification (I expect more clarification as the season goes on but am curious to see your thoughts):

F. Polycarbonate
H. Aluminum sheet, 90° angle, u-channel, tube, bar
Q. PVC or CPVC pipe

In particular I am interested in manufacturing my own wheel with a "U" cross section (think of a pulley) where the radius of the "U" in the wheel is 1.74 inches/2 = 0.87". This would keep the minibot on the pole very nicely.

Can I machine or form this type of wheel out of polycarbonate stock?

Can I take a piece of U channel aluminum and carefully heat and bend it backwards using a steel guide to create this type of wheel?

Can I get four PVC 90 degree elbows, cut them in half along the radial center and glue them together to create this type of wheel?

Also - can the aluminum pieces be welded?
