Hi Jay,
I'm still building a sub; I was just going to use
the ambient as a stepping stone to try out the design &
chop & change if necessary. Were some positives
out of the post, as while discussing fire & O2 with
a
friend, he gave me the name of a manufacturer
he deals with that could fabricate metal domes,
that I'd given up on sourcing locally.
Regards Alan

Alan,
Sorry
to hear that you are giving up on your ambient sub. While NITROX would
pose issues when used with an ambient sub, the problems can be solved.
Interesting you noted the ocular toxicity when exposed to high oxygen
concentrations over time. Briefly researched this issue a few years ago
for a buddy who made several dives a day with NITROX and used oxygen for
decompression as a commercial tropical fish collector. He noted a rapid
degrading of his eyesight with the oxygen exposure. I found only one
citation covering this in Bennett?s book on DCS. After further research
by his eye doctor, it was a confirmed factor in his need to have laser surgery
on his corneas.

The ambient sub is
now dead & buried. I'm considering using my acrylic dome as a gold fish
bowl.
Had done research
on oxygen toxicity & was aware of my parameters to avoid central nervous
system
toxicity &
pulmonary & ocular toxicity. I was intending to have O2 monitoring
but as you advised, they
can be suseptable
to moisture & in an ambient there is more of that.
As said, the main
flaw in this plan was the fact that When you got in, it would have a normal O2
concentration
& so if you
cruised under the surface you'd very quickly deplete your O2, with no
nitrox comming in.
It's great to be
able to submit these ideas & have them critiqued. I thought I was on to a
winner there.
