Finally pieced together my CO2 system.
Cost me about $105 to piece together all the parts including the tank (that I scored for $15 filled from CL!). Took about a month of intense research on parts and looking daily for the best deals. Definitely not worth the savings from buying a complete set here if you are not in it to learn, and only doing it to save money. GREAT learning experience though!
Victor VTS-253B Dual Stage Regulator
SMC VDW250 Solenoid
Swagelok B-ORM2 Needle Valve
10lb Steel CO2 tank
DIY syringe bubble counter
Ista Max Mix Large CO2 Reactor
I know the post body is unusually long. This is due to 2 reasons:
1. I didn't feel like spending a whole bunch of money on fittings after all the hard work to score low cost parts. So I used whatever fittings I had on hand and frankensteined it together.
2. I don't have a vice, so I couldn't get a wrong fitting on the regulator itself off. I ended up having to put together some parts to step the NPT size down, thus the extra fittings between the regulator and solenoid as well as after the needle valve.
It may not be the prettiest post body, but I think it looks awesome! Some pictures for your viewing pleasure.
