[PSUBS-MAILIST] motor pod

[Alan via Personal_Submersibles]

Hi Brian,
I was loooking for a very good link I posted on psubs about sealing canisters; by a firm
that specialised in building them. Can't find. Only have my Ipad & it's bookmarked on my laptop.
Someone else may have book marked it. It gave various sealing options & gave the pros & cons.
Here is one of many articles.

This one is based on the book "underwater robotics, science design & fabrication".
If you Google sealing a canister or home built canister you may find a few designs to choose from.

Where I'm at right now is a 10" diameter pipe with hemispheres on each end, the hemisphere with the motor shaft coming thru will be welded on but the other one will basically be like a small hatch with an o ring on the hemisphere side.  And instead of a hinge I'll have a bolt in the center ( with o ring) to secure it down.  I guess I'll need to have some sort of finish ( like stainless) where the hemi "hatch" mates to the pipe, and machine a o ring groove.  I will have to add some small flange to those edges since the pipe is only .365 thick.  I would like the option of either having the pod oil filled or dry .   For all the Kittridge folks out there, is this basically how your motor pods are sealed?
