Team 2470 - The Blitz Team starting cutting out their frisbee launcher with the school’s new plasma cutter today. The launcher is assembled from 6 sheets of steel, you can see 5 of the sides in the below CAD drawing. We decided to add a sixth side today for stability. You can see a video of the plasma cutter in action here. http://www.youtube.com/watch?v=RUpf_stUnaw

What made you guys chose steel over a much lighter aluminum? I can’t foresee a shooter producing more load than some .090 or .125 could handle.
Other than that, it looks good! I love me some nice CNC plasma cutting!
Second the aluminum suggestion. We’ve cut 0.050" and a tiny bit of 0.090" 6061 on a CNC plasma cutter with no issues. The blowout/edge finish is much worse than a waterjet or laser, and it takes a bit more manual cleanup, but definitely usable for FRC.
Are you planning on supporting the end of that shaft (where I assume there is a CIM mounted to a wheel)? It’s highly recommended to support both ends of a shaft when possible.
I agree with you guys, I would prefer aluminum but when your sponsor donates the steel and offers to weld it for you, we can’t complain. We would have just purchased some aluminum and sent it to the sponsor for welding but they do not weld aluminum unfortunately.
There will be no shaft to support, we are directly mounting to the CIM via a 8mm key hub from AM.
