Just built another one for a member. I came really nice. I used all nickel plated fittings and I added the capability for a second needle valve. This is a nice addition for doing more than one tank. I even figured a way to inexpensively add up to 5 needle valves on one system! What's kinda cool is the manifold is quite adaptable to normal sized Co2 regulators as well and it is only the size of a quarter.
Also in the works is an adapter to the larger paintball style tanks. I am working with someone who thinks he can make these. I decided to go this route because of problems with the only place I could find the adapter- the engravers store. I contacted the engravers store that is posted on page 1 and the guy was a total jerk. He would not sell me the adapter even though I had cash in hand. I even offered him more money and he wouldn't budge. He said it was against his insurance regulations to sell to me, but apparently if you by one of his $1000 engravers it's ok
Couldn't believe it. What bad business to turn away a paying customer. It must be nice to pick and choose.
If anyone is interested I can help you out just PM me if you have questions. If you are not much of a DIY type I can also build it for you. I have spare parts too for it so if you want to build one let me know because chances are I have the parts you need left over from my project as a lot of the small parts only came in bags of 10 and it would be ashamed to not put them to use if someone needs them.
