Dan, Sounds reasonable, I'll have to get my
basic list, and wish list together and see what types and sizes of connections I
will need/want. Then see if I can fit them all in the main assembly of my
boat. I would just hate to have to cut into and weld on the hull down the
road, if I can plan for most of it now. I've been working on sub
assemblies for my sub, and bit by bit the whole puzzle will start to come
together. There are always adjustments when that happens of course.
I can see one front head plate easily being used
up just for five or more lights, a camera, and a video camera.
Then the other plate for pneumatic control of the mushroom vent and future
grabber arm. Having one of each side of the front head helps in balance
some. For the rear head I have the need for power to the two stern
thrusters, and at least three lights, so I might get away with just one plate
there centered on the head. I'm thinking I want to move the flood valve to a
more forward local, since I plan to use it a fair bit for wet exit
training.
I have not decided if I'll place a O2 tank in
under the rear MBT like Alec did, or install two smaller ones just forward or
aft of the conning tower basically like on Cliff's R300, but under a small
standing platform. At some point I would like to have a number of sonar
units. At least one pointed forward, one back, one up, one down, one
starboard, and one port. So that's at least six small thru hulls I need to
plan for. Then we have the communications system David and crew are working on.
Man is sounds like I need to just take a machine
gun to the hull, and when the smoke clears, just weld in a thru hull over every
bullet hole. ;)'

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.

Plate 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

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.

2009 17:53:03 -0500 From: vbra676539@aol.comBrent, It
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
