[PSUBS-MAILIST] SPHERICAL PENTAGON

[Alan James via Personal_Submersibles]

How thick is the sphere going to be?Do you have the book by Jerry Stachiw on Acrylic?I wonder if Emile (Netherlands) can press 2 hemispheresthat big?I think it would be quite difficult to do. Maybe you would have to find an ovento fit the sphere in to anneal it after gluing.I spoke with Guy Richards the commercial director of Blanson, & he told methat gluing thick sectioned acrylic was quite an art. They made & joinedthe 2 x 4" thick hemispheres on the Triton 3000 sub.Cheers Alan

I once suggested that it should be possible to write a simple program to 
determine the size of the pentagons that would result in a given 
diameter sphere.  It never went any further than that (I had classroom 
work to complete!) but I still think it was good idea.
