[PSUBS-MAILIST] Superstructure question

[John Kammerer via Personal_Submersibles]

Carsten:
 
I have a question on the Euronaut topside superstructure! Did you use 
steel or aluminum? What was the thickness and spacing of the angle iron 
supports. What was the deck / side plate thickness?
 
I am considering aluminum 2" (50.8mm) x 2" (50.8mm) x .125" (3.175mm) 
angle and deck and side plates of .125" (3.175mm) thick. The angle at 2' 
(0.6096m) spacing.
 
Your input would be helpful. You can contact me off line a 
subvet596 at optonline.net
 
Thanks.
