Building a WTC: - One way to do it..

[robse]

I'd like to share with you guys how to build a watertight compartment. The solution you'll see, has tested tight at 2.5 bar (Both compartment and internal hose system), that's the pressure at 82 ft.
Surf to http://hjem.get2net.dk/robse/pages/SSBN/SSBN.htm , and look under "My Results", "WTC1" and "WTC2"

A little "teaser":

Thank you for detailing the construction in your website.
Very educational !

As an observation from partially looking through
the rest of the site,
I saw you use a mechanical device to level the ship.
Did you put in some PD (proportional-differential)
circuit ? otherwise you risk that the boat in
correcting the previous error, creates the next one.
(this is called overshoot, and leads to the boat
never getting level but porpoising)
Given you technical expertise, I assume you have
given this a thought.

Ronald

Hi Guys,

I am building my first WTC from scratch. I have the 3" plexiglas tube cut and the end-caps made. Next step is to make the tray for the interior electronics, servos, motor, gearbox, etc. I have noticed that some folks place their gear box on the wet side of the WTC end-cap. This would save space of course. I am planning to build mine inside. But here is my real question]http://www.subcommittee.com/forum/icon_lol.gif[/img]

I wouldn't use Nicads in a wet space. Either make room for them in your main cylinder, or build an extra WTC especially for the batteries.
