 Hank, I'm sure that you sorted out your quality control issues the last time around, but if it is necessary, I can make a site visit to EE on your behalf.Sean

Greg, I do not have a plan for getting on site.  I have a plan to get there, East Coast that is.  I can haul it cross country myself.Right now it is a dream really, not a plan.  But Elementary 3000 started that way.  I do have it mostly figured out, and I have an EFA guy lined up through Karl Stanley.   I will have two heads pressed and machined at Edmonton Exchanger in Edmonton Alberta.  My original CNG sphere plan is to light.  I think the get! ting onsite part will evolve, I am sure money will make that happen easily.Thanks' for calling it "interesting" and not ridiculous. ;-)Hank

Alan,That really turned out nice, how did you mould the polyurethane? that stuff stic! ks likemad. I would leave the white gasket, it looks fine.  Either the gasket thickness is not even or the seat is not perfectly matched to the Lenz.

 Pressure tested my light to 1000 psi for an hour using the water blaster 
& no leaks! I didn't have a pressure relief valve in the system as I do with
my air pressure set up & it was a pain getting the chamber lid off. I had
thought the water blaster would have leaked a bit of pressure but it didn't.
The sealing system for the wires was a 3 layered process; encapsulating the
wires in the epoxy, then coating the insulation for an inch up from where they came 
out of  the epoxy, & over the epoxy with a 2 part heat activated pvc glu! e that
they use on inflatable boats. This glue worked a lot better on the pvc insulation
than several others I tried like E61000 (supposed to be better than shoe goo),
3M 5200 & polyurethane.
Over this, to tidy it up & act as a cable support, I moulded polyurethane.
In the attached photos the white ptfe gasket that the lens sits on looks wet
but it is just the compression of the lens against the gasket. I don't like this
from a cosmetic point & may change it. The 2 objects with the light are the
male mould for the polyurethane cable support & the silicone mould for the 
same.
