I believe you got a somewhat close look at ours when you were over in our pit checking out our ball elevator for its spitting capability.
Team 2410 had two different designs this year. Our original design was one a la 1114 and 217 from Aim High (2006). The quad wheel pitching style shooter. It…didn’t exactly work out for our team as it did for those teams.

Like none. If I had to quantify it, probably somewhere around 10-15degrees of the wheel itself.
Our second shooter, whose information can be found here: [Link to be added when I can find it]
It was a student designed, custom fab whose design looked remarkably similar to Titaniums…
minus the lawn mower wheels of course. Each 9” aluminum wheel, 1” od with ~11degree chamfer towards the inside, weighed about 2lbs each, and we were running at 3000rpm.

Variable, though stayed at somewhere between .25 and .75

Originally 65, though we ended up modifying it to I believe somewhere around 68-70ish or so.

Shooter tread material would also be nice to know.

When you have a 2lb wheel moving at 3000rpm, DO NOT use a roll of duct tape as a brake pad. It will shred through 3 layers of duct tape. Residue will be left on your shooter. It will vastly improve the range of your shooter. You will have to drop the power by almost 70% to compensate.

Please also comment on how much you felt variation in ball density/squishiness affected your shots (although I understand this is purely anecdotal).

The first shooter we designed was vastly effected by ball density, namely because of the significant compression we placed on the ball. As soon as we backed off the compression down to only half an inch, then ball variation had basically no effect on our shot.
