Re: Using an air cannon to launch the balls - Arial Assist

The nylon bag around the ball will make sealing against your air cannon aperture quite difficult. Personally I would not try it.

Do you mean that if ball is a tight not a enough fit in the canon bore, then when you apply air pressure to launch it, the ball will not be deformed enough to keep a good seal, or perhaps the pressure may deform ball too much and make it start to act like a brake?

one can imagine that if there were a fixed air gap around the ball it would be difficult to launch and that a zero air gap (a good seal) is ideal - so how does having that nylon bag compromise the seal, how much air escapes without doing any work?
