Re: Whats best valving for pneumatics

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 va...

Re: Track pumps and Co2 inflators

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 ....
