Hi Brent. I think maybe most of the psubs I've seen were painted at the
hatch ring just because of cost. I don't see a problem as long as there's a
really good epoxy paint being used.
On the gap.....Some are closer than others due to the O ring size and
hardness, but again, I don't really know. The Parker info I was using said
basically make it as tight a match as possible, make sure there's no radial
scratches or gouges from machining, and they give a "squeeze" factor for
oversizing the diameter of the O ring. I went with the dimensions the salesman
gave me and I think I have a problem, but testing will answer that one. I may
need to get my hatch re-machined and then get a bigger O ring. If that happens,
I'll likely dovetail the groove a little to keep the O ring in place, as it
falls out right now. I just KNEW that info was no good, but after reading other
sources, and waiting and waiting.........I went with it. Thankfully I have
lots of steel there to add some depth to the groove. Frank
