really? the balls are quite grippy. and what if its not bent?

Lexan isn't very hard to find, although you'll probably have better luck looking for polycarbonate(the generic name). McMaster-Carr has it available in various thicknesses and sheet sizes. Part number 8574K63 is a 24" by 48" sheet of 1/16" thick Lexan, that should be enough for your purposes. Alternatively, you could find it in any size and thickness by looking under Raw Materials -> Plastics -> Polycarbonate.

If you don't have the money, try asking some nearby teams if they have any extra they could give you. I know lots of teams have extra hanging around and I'm sure they'd love to help out.

since you guys are rookies, i dont know if you will remember in 2002, we used soccer balls. on our bot we installed curved lexan strips on the front and back where our bot had an opening area... when the balls hit it the bounced off. you must make sure that they are close enough to the ground so they too dont run on top of the balls. the 1/4 lexan will be as springy as a spring, so they will just shoot off of it.

lexan is the easiest way to solve your weight issues...but if you have the money, get sheets of carbon fibre. def. a way to go if its a serious weight issue .




ps. carbon fibre sheets are about $80 for a 3x3 sheet..
