I've been looking at experimenting with a simple pneumatic prop idea, but I don't have the budget, space, or inclination to invest in a shop compressor at the moment. What I have is a decent-quality 12V portable compressor (like for cars) and access to a paintball compressed air tank (with Schrader valve). The tank is rated to 3000PSI, and I'm not looking at using more than 90. Is there a safety reason why this would be a bad idea? Is there a practical reason why this wouldn't work? I know the tank is small compared to even a small shop compressor's reserve tank, but I'm just experimenting at this point, and I don't need a lot of throw. Thanks!
