I am getting myself ready to strip down my old [spare] regs and learn to service them.
They are Oceanic SP5/Alpha 8, they haven't seen a lot of work over the last 18-24 months and still breathe fine, could prob'ly do with a check out and clean though.
I have just made my own manometer based on herman's design. (Thanks herman.)
Checking my old primary (which is now going on my bailout bottle) the cracking pressure still comes up with a respectable 1.125" which is within the specs of 1.1-1.5".
One thing I have found is it is very hard not to get the gauge 'bouncing', you really have to draw on the reg very smoothly so as to get an accurate result. I am wondering whether there is a way of dampening this, maybe by putting in a small restriction at the bottom of the 'U' to slow the water movement.
Obviously this would slightly reduce the responsiveness of the gauge tho'.
Next is to order an I.P gauge I think should help detect exactly when the reg 'cracks'.
Would be interested in some feedback.
