Re: pic: Wheelie Bar
Our team, 2506, uses the same McMaster-Carr press fit aluminum framing system for our chassis and drive base. We also use the ribbed type extrusion from that series, in combination with the plain type. It works quite well, provided you mill the edges flat and make sure all the dimensions are correct before you assemble. taking them apart can be a pain, but is do-able.
537 (the team i was for my first 5 years of FIRST) used it in 2007 for their chassis as well. It held up fine in competition. To make sure, they added pop-rivets at each connection point to ensure the press-fit plastic & steel connectors wouldnt come out.
Highly recommended stuff as far as i'm concerned. It leaves a clean finish, and it's light comparatively.
