I am working on putting a pair of 1940s bushing 38s into service as singles for my 10 y.o. (my 72s are a bit heavy for him and the kid basically doesn't breath!). jrltenn was gave them to me (Thank you!) with a year left on the hydros, and new bushings, and a manifold (that will be set aside for when Ryan outgrows the 38s as singles).
Rob at The Scuba Museum hooked me up with 3 old post valves to try to rebuild (Thank you!). 1 Dacor, one Healthways, and one Superior. Taking them apart, the Healthways and Superior appear to be the same, and the Dacor is noticabley different. The Dacor is set aside for now due to a missing knob, nut, and stem thread damage. The Healthways I just got back together, and I have some questions... First being that I only get about 3/4 turn out of it from closed to as open as it will go. Is this normal, or am I not get enough range out of it to be fully (unrestricted) open? Secondly, has anyone found a source of 1800psi working pressure burst disks that works in these? I am going to try some paintball burst assemblies, but don't hold to high of hopes (ordered before I saw Surflung's threads referring to them not working).
I guess last question at this point, is does any one know of a pdf of Basic Scuba? I know it's the reference manual I probably need most, but can't find a copy that isn't hundreds of dollars as a collectible.
Respectfully,
James
