Brent,
Some of the stuff you listed will always be needed to
operate the sub. For through hulls that will always be used, like MBT
connections, there isn't any reason to run them through plates. Just mount
through hull fittings directly to the hull in places where they will be best
located. Only install the plate through hulls where you may use them for
changeable stuff and future additions. Why create stress areas, more
welds, more O-rings and places to possibly leak where you don't need them?
Six is way to many.
Most likely one plate will do you, but I can see as many
as three, one up front down low, one somewhere in the aft end cap and maybe
another on top behind the conning tower. All you really need to do is
get through the hull. You can run piping or wires outside the hull as
needed too.

Multi Thru Hull Options
Vance, The Captain
didn't remember installing the plate thru hull, but it might of been his
install. The two plate thru hulls I'm planning for the front head, are
for lighting, a future manipulator, still and video cameras, sonar, air for
filling the front MBT, pneumatic actuation of the mushroom vent, etc,
etc.. So the one just forward of the conning tower, might be used for
some instrumentation I want in front of the forward viewing area, some
additional lighting, perhaps cameras, and a large light that I can rotate and
change the angle of, sort of like a police light, by means of pneumatic or
electric actuators, and a couple other future items. In all I'm thinking of
installing six of these S201 type plate thru hulls. Two in each head, and two
near the conning tower under small standing platforms much like seen on the
Delta sub, but a bit higher to make room for the plate thru hull connections,
and keep my feet dry.

As the sub was used extensively, I'd
say somebody did some design work, possibly Captain Kittredge himself. It has
that look. What would you use the front penetration for? If you are planning a
manip or something that needs a dozen or so pens, I think that I'd consider
putting it forward and down somewhere to get it closer to the source, and cut
down somewhat on the tube bending.

Vance, I just
added five additional pictures of the plate thru hull on my K-250. Two
show a interior view, and the others show some basic measurements I took some
time back before I purchased the sub. I can get better measurements
before I head south, and make up a CAD model and drawings for
you.

Vance, Having
easy thru hull options is useful. I will be adding another plate thru hull
assembly in front of the conning tower as well under a small standing
platform. I also want that same type of platform behind the conning
tower. That existing plate thru hull, looks like they just used a
standard pipe flange and welded it in. My friend had SS ones like that he
installs in his SS tanks I could use if I wished. I don't have all the
data here with me, but if I recall correctly the tube has a ID of 6 inches,
and a wall thickness of 1/4". The top plate is 5/16" thick and the
flange is 3/8" thick. The OD of the plate is 8 3/4". I was
planning or replacing the steel plate with a thicker 316 SS one.
I've
now been thinking about cutting off the flange and installing a smaller
diameter plate, and attach it internally sorta like the ones on the S201, but
use welded on SS tabs instead of the SS retaining ring, to make it even easier
and cheaper to fab up. This configuration might be the cheapest and easiest to
make and install in the tube section or the heads. Basically you just
start with a cheap steel tube. I'm planning on making a CAD model shortly, so
I can show you exactly what I'm thinking.

looks like a pretty good way to get multiple connectors without having to
chuck the sub up in a mill. How thick is that flange, and how thick the
tubular penetration? Assuming they were an assembly, it seems like you might
be able to install something like that without distorting the O-ring mating
surface. Maybe I'd be tempted to repace the disc with a stainless piece, but
hey, it's there, right? Run what you brung. Vance
