Timely advice Vance,
Have just bought a heap of swagelok fittings
(ouch expensive) & stainless tube.
I'm using solenoid valves as well as a manually
operated system for ballasts etc,
so it's going to
be looking like spaghetti.

Alec,
Don't know if you're onto this
trick, but when you get ready to re-plumb the high pressure air (as
mentioned in the caption of one of those photos), we used to bend a template
set out of 1/8" aluminum tig rod before committing to the stainless (which
is very unforgiving, especially in small pieces, as you have already
discovered). You can get your lengths and angle changes right to a gnat's
hair with the rod, and do it on the cheap. Go centerline to centerline of
your fittings, cutting to the depth required for your Swagelok fit-up, but
remember to add/subtract an additional 1/8" to the tubing for arcs in
stainless. Try it with a chunk of copper tube, if you like, but doing it
before you do it for real is a definite improvement over the sweating and
grunting while sitting in the sub. You'll get exactly what you need in
stainless without wasting the HP tubing in the process, and you can build
the whole thing on the bench--and it will fit like the proverbial
champ.

Yesterday I finally got to dive Snoopy
extensively with all her new mods, and they worked like a charm. Therefore I
thought I'd share...
