Thanks for the advice. I think i am going to go with the bulk co2 and a holding tank. I did not know about using a holding tank to solve the freezing problem so that problem is out of the way. Now i just have to build the gun. Will post pics when gun is finished
Thanks again,
Gene

If I use a bulk tank. will I be able to use the qev from mcmaster? And do I have to do anything special to the gun because i used co2? I have 2 nos bottles already in the shop. Could i use those? Thanks for the help.

I am going to build a chainfeed remote controlled t shirt cannon for a demo truck we are building for the CES show in Las vegas. My question is what type of air compressor would i need to mount in the truck to get a good rate of fire? I was thinking a shot about every 15 seconds.
