I have a bunch of 72's but none of them have J's on them. With this new DH toy of mine I want to get a couple J valves and change out a few tanks because I want to try vintage.
My questions:
How do J valves work internally? Do they need to be rebuilt or any kind of mainenance. Is there anything inside that can fail making the lever not do what it needs to do.
When the lever is up, how does the breathing difficulty happen. Is it sudden or is it gradual. And when you pull the lever down what does the PSI generally go up to?
After the lever is pulled down is the breathing back to normal or is it somewhat restricted?
I also have a source to buy as many used 72's with J valves that I could possibly want. Getting the valves is no problem. I guess I will just look at the tanks and valves and pick the best ones I see. Are there any year perameters that anybody knows are better than others, or should I just grab the newest ones according to production date. What about brands - any prefferable over any others?
Fianally, I will have to fab a lever wire out of stainless unless I can find one somewhere. That shouldn't be too hard. I guess I will have to fab some kind of guide rings that will go on the tank bands too. Ant suggestions. I've seen at the bottom of those wires there is a loop or ring to grab onto.
