Do you have a drawing or data
on Phil's tilt/demand system?

Rick,
I built my K-350
according to the plans and made the Phos. bronze fittings. If I had it to do
over again I would skip that part and bring the O2 into the cabin at low
pressure instead of high. Stainless steel is not favored for HP oxygen
service. Phil Nuytten has the best system going with the tilt / demand
valve.

trying to get as many thru hull fittings welded in as I can before welding
the end caps on. For anyone who has the plans for a K-350, did you actually
follow drawing 041-2? it is the Phos. bronze removable piece for the 02 to
pass threw and looks quite expensive to machine if not doing it yourself.
I would like to hear from
anyone regardless of boat type that uses an 02 life support system what they
welded in for a threw hull fitting. I can't see why I just can't weld in a
schedule 80 ss 316-L pipe coupling then screw into that a HP valve
then HP to LP 02 regulator then a proper flow meter for 02?? I
would 02 clean the nipples and coupler of course. Also any
feed back for the ID of pipe I should use would
be appreciated.
