Originaly posted by Rocketbiker,
I posted a similar question in construction materials, but this one has a little extra to it. The first time I asked if there were any drawbacks to not using a 1/4 turn valve after the bernz valve, only at the end. I got good responses, affirming my belief that the first 1/4 turn is mostly for convenience of use and calculating the volumes.
I finished mine tonight and went with this scheme. I actually like it very well, because I am not using a regulator, and this allows me to crack the bernz a little and acurately put in as much pressure as I want. At least as acurately as I can with this piece of crap guage I have. My next investment.
Anyway, next question is, when I determine what pressure works best at a given temp, will that pressure work at other temps? I know temp affects volume and pressure, but if it affects the volume in the meter pipe at the same pressure it will also affect the volume of air in the chamber right? I guess I'll know for sure when I try it out, but I was just interested in some of your opinions.
