Yes, my plan is like Dan Brewer's. I am trying to
minimize as many "0" ring seals as I can because I feel that if there
is a major "0" ring failure, you would ship more water before you can surface
than if a threaded fitting starts to leak plus I will put a couple of extra
holes with plugs in it for future possibilities like Dan did.
Frappr,flicker,fritter and flack,,, god I am behind the
times! Sounds like a law firm!
I would like to the tricks and am all ears.

Hi
Rick,
I see now, says the blind man as he spits into the wind.
It's all coming back to me now. Your going to weld in your SS plate,
which will give you more area to drill holes, then if that size of plate was
used in a removable configuration. Your not alone in using that config.
since Dan Brewer and Emile have done that as well. It's a very usable
configuration.

I prefer using a removable
plate type, since you can add holes and thread then if you wish much easier,
and if at some point you need a totally different hole pattern and/or size you
only have to make a new plate. This way no welding is needed later down the
road.
See if you can send the pictures to me off list if you can not
upload them to Frappr, Flicker, Fritter, Flack, or the like. There is a couple
of tricks with Frappr if you would like to know them. I sent some
pictures to you the other day, if you didn't see the email, it will likely be
in your junk mail folder.

Hi Brent,
I'll look around and see if I can find some better shots
of the SAT penetrators that show them closer up, if not I will send you the
one I have at hand. I have never posted any pictures on this site and am
ashamed to say that I am quite computer illiterate compared to the majority of
members on this site judging from a lot of the neat CAD drawings I have seen
people whip up. I blame it on too much helium, or not enough, back in my
SAT days.
I was planning on cutting out a 6" diameter piece of the
5/8" plate and then cutting out a slightly larger hole in the dished end to
allow for a proper root gap and then doing a full pen weld. My reason for
putting it into the dished end is because it is thicker than the hull plate
and I feel it would be stronger due to the dished end curving in all
directions rather than the hull plate curving in only one direction. I
certainly could be wrong about that and am open to any
suggestions.

RE: [PSUBS-MAILIST] Large Plate Multi Thru Hull Options
Hi Rick,
Using those left over SS plates is a
good plan. Phil recently mentioned he does that as well. They don't
give away the thick SS plate any more. ;)' I've
change my conning tower design because of the new SS plate pricing.
I've got a couple of ideas of how I can TIG weld in some SS sleeves and/or
threaded blind sleeves to attach the SS tension rods or bolted on the rings,
to hold the thick acrylic cylinder in position. Then ease the corners of the
seating groove for the acrylic cylinder, and use a soft gasket to seal the
parts together. This way I can just use steel plate conning tower
seating flanges.
Do you have any pictures of the SAT system thru
hulls? They would be interesting to take a look at.
I just
found some more pictures of the S201 interior attachment means for there
plate thru hulls. I can now see that they used three bolts to hold the outer
SS plate in place with a SS ring inside, instead of just two bolts. This if
more like what I would expect from Paul. He also uses just three light
weight attachment points on his hatches.
I also found some
pictures of the plate thru hull design used on the Alicia submarine. They
are mounted on the top aft end of the tube section of the hull, instead of
the heads, and so they are a bit different. They don't have the nice angle
on the outside surface as those on the S201. He installed a number of
basic individual thru hulls on Alicia's rear head as well. But he didn't do
that on the S201's rear head. He instead opted to use four large plate thru
hulls, of the same size and configuration as the ones on the front head.
This makes manufacturing and installing the parts easier as well. This
I feel shows the fast evolution of his designs.
Are you wanting to
make the total outer SS plate diameter 6", or the ID of the welded in thru
hull 6"? If you have total outer SS plate size of 6", and you have say
a 4" ID of the welded in thru hull, I would think it wouldn't give you
enough room to fit in 8 1/2" holes, and all the
rest.

Hi Brent
I was hoping to use the ss drop I have left over from
cutting the sealing ring for the hatch on my K-350 if possible and it's 5/8"
thick. I will need 8 apertures in it for four functions for my mechanical
arm but not sure of the hole size yet until I can determine flow and lifting
requirements. I am guessing approx 1/2" but may be wrong. I would also like
to keep it at no more than 6" diameter if possible for obvious reasons. I
went back and looked at some pictures of some Sat systems I used to
live and work in and all there penetrators seem to go threw a removable
blind flange.

[PSUBS-MAILIST] Large Plate Multi Thru Hull Options
That's a very good question Rick. One that I've been
pondering since yesterday. I was planning on having one large one
centered on both the front and rear heads and up a bit. But with the
mushroom vent assembly being in that area, the lines coming out of the
plate would get in the way. So now it looks to me like my best
option is to put two smaller ones towards the sides, much like what was
done on the S201 as seen in these pictures linked below. As you
might expect, the larger the plates unsupported diameter, the thicker
it should be. What that is we'll have to work out. Also we
need to consider how many holes of what size there will be, and
where. I was thinking of using a .5" or .75 thick piece of 316 SS for
a plate with a inside unsupported diameter of 6 or 7 inches. I need
to guestimate the number and size of items I want to go thru each plate,
and then leave some room for future needs/wants. Currently I feel
I'll need a good amount of thru hull connections for future pnuematic
acturators, sonars, cameras, more lighting, and paint ball guns for sub
tag. May be not the last one. ;)' I know a few
other guys that wished they had added more thru hulls for future unknown
needs/wants. http://www.msubs.com/Images/Services%20Images/Pressure%20Vessel%20Design/Pressure%20Vessel%20Design%20-%20Main%20Image.jpg http://www.msubs.com/Images/S201%20Images/S201%20-%201.jpg http://www.msubs.com/Images/S201%20Images/S201%20-%203.jpg In
this picture of the interior of the S201 you can see on the center left
side, the way Paul designed the plates to be attached from the inside,
with a simple SS ring plate and two bolts. This way he does not need to
drill into the welded in seating ring, and the ring can be made with a
much cheaper steal, rather then use very thick SS. I'm working up a CAD
model to better show this configuration. I'm not sure if a O-ring or
gasket in the SS plate will be the best option. I'm leaning
towards a O-ring configuration.

What diameter and thickness ss plate are you going
to use in the front and rear heads?

RE: [PSUBS-MAILIST] The Long Arm of the Claw
The rotary thru hull is
rusted and has male threads on the exterior that are rusting quite
nicely. I'm changing all the thru hulls in the sub to 316 SS
couplers, so while I'm at it I might as well change that one as well, so
I can get all the hull welding out of the way. I'm adding two large SS
plate type thru hulls on both the forward and rear heads for what ever I
might want later as will as current needs. This way I can install
and run a pnuematic, electric, or hydralic arm later.
I just figured out how Paul
Moorhouse attaches his SS plates without any bolt holes in the main
hull. So I'll make a CAD model to show you guys what I thinking will be
nice to use on my sub. http://cid-5085d10eb6afe47c.skydrive.live.com/self.aspx/Claw%20Removel/SS%20Claw%20Control%20Bar/DSCN7320.JPG

I'd leave the rotary penetrator plugged for
when you can think of something to do with it, and build something more
useful for a manipulator. That's if you can find it under the
snowfield. Vance

Hi
Vance, The
winter up here is pretty deep. I went home the other day to shovel
snow off my buildings and Van and it was a four day chore. I had
the sub ready for blasting outside, and then was called away from
home to work. By the time I got back the sub was under 4 plus feet of
snow. The pictures I took are pretty funny. I'll post them in a
bit. So the sub is underwater and in the deep freeze for save
keeping. I have been debating for
some time now if I should leave my original claw arm on the sub.
It's very hard and slow to actuate. So at the moment
it's used for just a crash bar, like Alec uses his for. I can
make a proper replacement crash bar, then later add a more functional
arm. So it's mostly a matter of nostalgia at the moment. What
would you do in my place. I take it you could see the
pictures right? Jay try this link to the
root for the albums. If that doesn't work then I'll post them on
Flicker. I tried those links when being signed out and being on
Windows Explorer browser and had no trouble. I also tried them on a Mac
in Firefox and had no trouble. The only thing I can see that is
different in the link from the address bar from the ones in my posting
is the %20 sign used in place of spaces that are put in automatically
when I copy and past the links. Perhaps they are causing the
trouble if you copy and paste them. I tried them both by just
clicking the links and copying and pasting and they worked good.
The albums are set as public just like I did before. Hope this
works.
