Anyone else changing from Bead Blasters for tires to potato of golf ball launchers
I have found that the Velvor BB valves and similar BB have the perfect valve for dumping the air out in one go than the old way especially with the push button release and metal valve body than the plastic sprinkler ...

I am going to have a go at finding a longer barrel about a meter or yard long and use a 2kg co2 fire ex bottle but pump to 100 psi which hopefully be equivalent to using a 1 kg bottle at 200 psi. 100 psi on most track pumps is not that much effort to get to pressure. I am also going to up the QEV ...

A bit new to the game and asked many ...

Air tanks are the best bet but my air cylinders are heavy dive cylinders for my airguns so a bit of a lump to carry about. I was thinking of a small12 volt car compressor to carry but i don't think you can get to 200psi at the most.
I did have a try with a Co2 bike pump cylinder but it was useless ...

Hi i am new to this great site. Been launching golf balls and other projectiles for years now by other means other than air and have got back into pneumatics again, so i have quite a few questions to ask. As a safety rule myself i only deal with metal valving piping and pressure chambers , as i am a ...
