Minibot Tetrix Modification?

[Bmarquez]

looks like me and my power drill are going to get very friendly tomorrow.... making a working frame out of sheet metal should be pretty quick to bolt together, and grind/polish/finish. According to the materials in part R92, sheet metal is allowed so i guess it was a silly question x.x.

i figure the extra zerospace allowed in a fully sheet metaled part will also keep the weight down and give me freedom in mounting/angling the pieces where i want them.

Thank you for clearing that up!

can i melt down the tetrix aluminum in a forge and pour sand castings to use on my pole-bot?

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?

Specifically sheet aluminum.
