AQUASUB

In my other posts like the I-53 Whale the casing used is made from PVC pipe and a simple mod that made it all happen and ever since I first did it a few years ago it has been great ! So simple to make and and lenght or variations in diamiter is available to the builder as PVC pipe has huge range of fittings and comes even in a semi clear vertion.

Bellow are just a few of the ideas I have on my boards for future subs.All use some sort of method to keep the cap or caps on iether draw latches or internal bolt.

The nice thing and super important designe feature is that the deeper or more external pressure is applied the tighter the seal is squezed.

Also with internal vavume applied as with my Non presurized ballast tank systemagain the seal becomes even better as vacume increases eventhough not enogh to be concerned about when properly done.

Yes I use what is outthere,why because its better, cheaper and its everwhere!
First diagram shows a cross section of the seal it self.

How come to you reverted back to using a PVC pipe here and not your so called "cat's meow" Aquacasing which you claim is vastly superior?

I did not revert back to anything,there both excelent each in there own way.The aqucasing has random acsses ability with state of the art sealling.
The PVC casing is cheaper and seals just as well with even more designe capability.

I am not a single minded bloke,mine is the only way mandate,no no inovation and new school of designe is my doctrin simple and universal aplications.
