I have a 20LB tank I just have to find somewhere to buy the gauges/handle and valve

if you have the valve for the top the regulator is easy
get a high flow oxygen regulator for a cutting torch
they make several different flavors of these things but you can get one for ~$100
it should have out-put adjustment from 0-200 psi ,any thing less and it is not high flow
change the fitting to work with CO2 and there you go
I got this info and set up from a welding supply house and NEVER have a freeze up
even running an air ratchet for long bolts or removing and reinstalling 5 lug nuts with an impact
we even used it to run a 3/4 drive impact at work a while back ,burnt through some "juice" but it worked
to break loose some 1" bolts, had to change the fittings to work with the 1/2" hose but this is way more than you will ever need
oh yeah and the same welding supply house can probably get you a valve if you need it
you will also need a cert. on the tank and that may cost you a few $$
if you pay tell them you want a hydro test not an X-ray test ,cheeper and better
best thing to do is befriend the guy at the welding supply house
take him out wheeling and then let him "hook you up"
