In less than half an hour the pressure drops way down, this is not the Magma factory air system, it is an aftermarket kit a guy (on this forum I think) makes.
I have the plastic strip and radiator clamp over air bleed hole on back, have teflon tape on fittings, O-ring inside the knurled cap, and the air tank with gauge I use does not leak at all. I am going to go over the connectors with another layer of the tape, but in the meantime perhaps someone has some suggestions?
Only thing out of the ordinary is the .356" die bearing surface is .749" dia, and oozes a bit of lube out from under top of die, (was .751" diameter, too tight, my friend with lathe took too much off) all my other dies are very close to .750", I had a Star with all the extras which performed perfectly that I sold some years ago, (yeah, dumb move), so I am reasonably familiar with them,
