    After some research and looking through my "junk" as the wife calls it, I decided to build a booster pump.

    I already have argon that I weld with, just needed a way to compress that up to higher pressure.

    I shot this video of how it works before the check valves came in.

    My check valves cam in yesterday and I tested it up to 4000psi.

    I thought I remembered reading about seal degradation issues using Argon as an air source for PCP airguns (Nitrogen seems to be the premier choice right now). I don't recall the property of Argon responsible for seal issues, and can't find the link at the moment, but thought you might want to consider it, if you haven't already..

    I've also heard theories that you will loose velocity as Argon is 'heavier' than air, but I don't know if this is true or not..

    D90, argon is a noble gas. Reacts w next to nothing.

    J, surprised you just didn't build yourself a better shoebox compressor:-) Or are you just working towards that?
