Re: Help With Off Season Project

Where is the air storage going? Does it need to move with the barrel or is it a flexible connection?

The first version of our t-shirt cannon had the barrel and "small" dump tank that were rigidly connected and rotated together in one axis to change elevation. If you do something like this and counter-balance the tank you can change elevation with a sprocket/pulley and a variety of KOP motors, I believe we used a Globe but something like the AndyMark PG27 Gearmotor would work fine.
