Our launcher is simple, robust and works. We use the smaller CIM with an 8mm hub coupled to a FIRST plastic rimmed wheel. On the wheel, we attached non-skid material (the stuff one uses for stairs for we old folks not to slip). we fabricated our launcher system with angled aluminum and some lexan. The most expensive stuff was the super slick Teflon tape we applied to the channels in which the Frisbee rides. Got that from McMaster Carr.
We use a cam (hand crafted from wood) system attached to a PG71 to push the Frisbees into the shooter. Our loader is made from Lexan as well. We don't have a large budget so it was hand crafted. Nothing like a heat gun to make the bends.
Please drop me a line off list (pm). I bought several more 8mm hubs than we needed this year. In fact I didn't pass the stupid test and double ordered. You're welcome to 1-2 if your team needs them. We don't have any more of the mini CIMS but I think we've got a regular sized one if you're in need as well. We hand fabricated the motor mounts for the CIMS. I could send you the CADs for the shooter and motor mounts if you're so inclined. It works and works consistently out to about 40'.
Again, drop me a pm and let's see if Team 3355 can help y'all out. We're willin' if you're willin' to accept the parts. That's how we roll...gracious professionalism!!!
