[PSUBS-MAILIST] dome and sub parts

[hank pronk via Personal_Submersibles]

Emile,That is a very nice size, 1500 mm, should be buoyant at 700m rating.  I would like to hear what you find out about them, like thickness and weather they are pressed or segmented.Hank

For the 26 mm about 300 meter .  The crush depth isaccording to Stachiw’s tables about 4 times the operational depth.  Has somebody on the lista calculation method for the crush depth?

 Hi,    For those who are preparing a sub project: I have afew acrylic domes for sale from stock. See this webpage for details. http://www.nordicsub.nl/acrylic%20mermispheres.htmlPsub members 10 % discount ;-) The Dome with 20 mm thickness has a OD. of 600 mm .For logistics an liability reason I can’t ship to the US  (directly)    Anyone interested is 2 or 4 steel hemispheres ofabout 1500 mm diameter? Next Saturday I will visit a company who is selling 4hemi’s that were intended for a 700 meter submersible. On the visit I will measure accurate and ask for a price.Half the price of new would be fine.    Best regards, Emile van Essen
