What to do with pneumatics in the off-season

If you look carefully at the back of the cylinders, you'll see what I imagine to be the magnetic reed switches supplied with certain cylinders. I think that as the cylinder trips the switch, you switch the pressure on the cylinders.

That's correct, we used the magnetic pistons with reed switches. The switches are wired directly to the solenoid valves without going through a controller. It's powered off a small shop air compressor. The two 12" X 1 1/2" pistons would be way too much for the kit compressor, at least at a speed that would keep the ice cream from icing up.

Well last night, i built a C02 powered potato cannon based off a Quick Release valve from a bus air brake system.

I like the ice cream maker. I want some ice cream right now.

At some point I may convince my team to make a hardcore teeshirt cannon. 6 Compressors, twelve Clippards... watch out! I'm thinking about trying to make a supersonic pellet gun, but it would need insanely high pressures, well above what the kit parts can take. (mmm, can you say 1Kpsi?)
