This picture shows the SS thru hull plates on the stern head of the S201. You can see that two have not had holes drilled into them yet or fittings welded on.

Here is a picture of the interior of my front head, as it is currently. The two that go to the sides were used for lighting, and the upper one for air to fill the front MBT. I was thinking about placing the center of the large SS thru hull plates about were the center of the side thru hulls are currently.

Subject: [PSUBS-MAILIST] Large Plate Multi Thru Hull Options
Date: Wed, 21 Jan 2009 20:20:39 -0800
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.

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?

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.

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.

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.
Regards,
Szybowski

Of course, it was 76 degrees here today, sunny and a few clouds...breezy. Okay, I can't think of a complaint. And there's some of you guys who up to your armpits in winter, and I do mean winter.
