Do you or any one else know the max depth manned or
unmanned that a K350 has been down to without problems?

Brian,
3/8" will require an extra couple of feet of hull length in the K design.
The elliptical shells are 9/16" in the K-600. Your sub will be heavier by a
ton or so by the time you're done with it, if you build deeper. That said, if
you need the depth for future plans or local conditions, then I'd recommend
building for what you need and be done with it. The price of steel will be
less than 50% higher than its thickness and weight suggest, and you won't have
to go through this but once.
If greater depth is required, I'd might want to email me off site
about the KSS, as it is roomier and weighs just a touch more than the K-600.
AND it dives to 250m/800ft in standard configuration. AND it won't cost any
more to build.

Hi
Jim,
On my boat a number of items will be independent of the pressure hull, like
the battery pods, air bottles, ballast tanks, and rudder
controls, but I see what you mean. I've been watching steel prices
and they are starting to creep up now after bottoming out. So I'm
getting a little antcy about waiting any longer. I'm thinking also to
just build a shallower boat first, and then later build a whole new upgrade
which I could swap out.

Hi Brian,
It's only my opinion, but there is a LOT more to it than the conning
tower. Any thru hulls, maybe battery pods, motor mounts and all the ribbing.
My thought is get started and do what you can and if the project takes
longer so what. That's part of the reason mine is taking as long as it is.
When I'm busy I have the money but not time. When I'm not busy I have the
time but not the money.
Best Regards,
Jim K

Hi All,
I'm having
a bit of a delema deciding wheather or not to go with
either 3/8" thick
hull or 1/4" hull. I'm thining that initially maybe I
should go
with the 1/4" now (so I can get this off the ground) mainly due
to
budget constraints and then at a later date upgrade to the thicker
hull,
which would take me deeper. My question is how hard would
it be to cut out
the conning tower( 3/4" thick) from the 1/4" hull and
paste it on to a 3/8"
thick hull at a later date? Would I need to grind
out all of the weld seam?
And would that adversly effect the metal in
that area by rewelding?
Thanks,
Brian
