Determine o-ring diAmeter?
Posted: Sun Jan 17, 2010 11:32 pm
Hey--
I'm working on improving my combustion gun vastly and one thing I need is a truly gastight projectile- which means o-rings similAr to jagerbonds UHMW rounds.
I'd like to not say why at the moment but basically say I have 2" diameter PVC how would I determine what o ring OD would give a seal- how much "squeeze" should the o- ring undergo in essence.
I know some of you might me wondering what gun I'm referencing, but you won't find it anywhere, mostly because I don't post most of my projects up here-- because i'm not satisfied and they get stripped down again- currently i've built 6 or 7 guns but only have one still operational-- and if I can figure this one out it will be posted.
So sorry for a super long probably superfluous explanation.
Thanks for the help-
