Frisbee shooter

[protoserge]

You need compression on the frisbee to transfer enough kinetic energy to it. Some of the 3M grip tape or other friction material will be useful on the wall. For the wheel, the BaneBot, pneumatic, and AndyMark hi-traction kit of part wheels worked well.

You can make a very effective shooter out of plywood. The hard part is indexing your discs so that you don't jam the shooter.

The purpose of compression is mostly to reduce slipping between the frisbee and the wheel, and the frisbee and the fence, to impart spin. Without spin, the frisbee will not travel very far. That's why most teams add some sort of friction surface to the fence. You want the frisbee to roll on the fence, not slide.

Here's what our team's shooter looked like:

We used two mini cims and I believe we geared them down slightly. The blue thing is a piece of foam similar to pool noodle material (I think what we actually bought was a yoga mat). This material gave us compression and and the wedgetop tread on our shooter wheel provided grip. Together these allowed for minimal slipping on the frisbee. We cut an angle into the foam to prevent the frisbee from walking up the side of the channel and we added teflon tape to the plexiglass rails that the frisbee rested on in order to reduce friction as much as possible.

We used a linear design that got plenty of speed. We used two pneumatic wheels attached to a CIM and Mini CIM, with distance from the edges of the wheels to the other side of the track 1/2 an inch smaller than the frisbee diameter. (We cracked a piece of plywood with our shooter around 80% power).
