Hi Alan,

 

I don,t have an answer for you because I am using larger soft tanks instead.

 

I welcome you to the group. I am buiolding a sub now and this group has been a fantastic resource for me. Some great members with a lot of great ideas.

 

You'll have to sift through and take what works best for you!

 

Welcome & Best Regards,

 

Jim K

Subject: [PSUBS-MAILIST] inflatable pontoon configuration

Hi , I'm new to the group, am designing a small 1 atmosphere sub. Have been diving for 20+

years and reside in Auckland, Newzealand.

I've been looking at the pontoon idea. One of my reservations is that the pontoon material

will be stuffed into any outlet/inlet hole at say 180 psi at 300ft.(a 2"diameter pipe was mentioned)

I'm concerned at it rupturing in time. Had thought of an arrangement of a plate with multiple holes

in it over the inlet/outlets. Any thoughts on this?

regards Alan
