In the list of kit parts, it states that we can use Plexiglas. When you state Plexiglas, is polycarbonate an acceptable material to use?
Is heat bonding, using a soldering iron a legal method of bonding Plexiglas or polycarbonate together?
A member on our team was wondering if a fastener could be used as a shaft as long as it held two or more things together?

Polycarb is acceptable as is Lexan

Yes this is acceptable as a fastener

I am trying to recall the wording FIRST uses in this case. I believe that if a fastner is not used to join to non-fasteners then it is not classified as a fastener. I know that there used to be a distinction between an axle and a link pin, but this got to be very difficult to distinquish. So… Link pins and axles CAN be used as fasteners but only if the parts are in close proximity to eachother. For instance a bolt that functions as an axle is okay if the rotating member and the fixed member(s) are substantially right next to eachother. That same bolt would not be okay if a gap of say more than a 1/4 of an inch seperates the two joined members.
It is still early enough in the competition that we have some wiggle room on this issue. If folks have strong opinions, voice them now.
