Ditto for me on the deburring tool. Essential for
clean tube ends.

I concur with Vance. The keys to getting good clean SS tubing
runs with Swagelok fittings are only use Swagelok benders, use the pre-swage
tool rather than clamping the fitting directly in the vise and most
importantly use a stiff piece of wire to bend out a template before touch the
stainless. I use a piece of 10 AWG romex wire and bend at centerline but
concede that 1/8 aluminum tig wire would work better. Using a template
lets you bend out the hole piece at the bench top rather than the boat. I also
like using there deburing tool. Cliff

For
production work,
Swagelok sells a pre-swage tool in various sizes. It is hard steel, much
harder than stainless, which clamps into a vise on your bench. Lots easier
(mostly) than fighting two wrenches or (god-forbid) a wrench and a crescent
wrench. You do the same 1 1/4 turns, but having it steady in the vise makes
life a lot easier. Using the pre-swage tool means all the torque goes to
making your seal and is not inadvertently distributed onto other components as
the system is built. Make it up outside, break it loose and when everything is
ready, just go put the bits together. Works great, lasts forever, and well
worth the additional outlay of cash.
Vance
PS: Swagelok sells their
own bender. Very good ones.

Hi Vance,
you are getting me confused now. Am no
plumber.
I thought all I did was stick the tube in the
swagelok fitting & do it
up 1&1/4 turns. Will take your advice on the
bender.

I hope you bought
mandrels for the swage ends. The females (tube end with nut and ferrule) are
infinitely easier to form in a vise, and virtually eliminate galling and
cross threading, among other things. Worth the investment if you haven't.
Trust me on that. And no hardware store benders and cutters either. Buy the
best up front. You'll be happier later. Good luck, mate.

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...
