Les,

there was a sphere around that size that was part of a submersible owned by Brian Cox, who passed away a few years ago.

I am not sure what happened to it, but someone else listening in may be able to tell you. It was the one redeeming part of the sub,

the rest was questionable.

Regards Alan

After many years and many hospital holidays, 🙂 I am no longer a financial member.

However, I am hoping that someone may assist me in the spirit of  Psubs.

If memory serves, there was a calc formula on your site of which I no longer have access .

Any way, I have a project idea that to continue with, relies on the minimum weight achievable for the following ;

 

A 2 meter diameter sphere with appropriate bracing material and with safety margins 

To dive to sea-water safe depth of 150meter (160psi) No doors No windows 

Windows and doors will add much I know, however, are details to be considered later only if the basic weight indication makes the project viable.

So basically, I need to know the framing and sheeting steel sizes and thicknesses to calculate the overall weight in this basic form. If positive at such point I will apply for re- membership to follow through with my idea.

I know this sounds vague and I am asking much, but could someone assist me in this very basic task, which I know not how to do. 

Thanking any member who might be inclined to assist me. 

Cheers Les  

Safe diving 🙂
