Re: [PSUBS-MAILIST] concrete submarine yacht

[Thijs Struijs <thijs-struijs@planet.nl>]

Hello Wilfried,

That's a great sub you built. What's the status of it now? (Did you sell it? 
Is it still in Austria or did you ship it to Colombia?)
Before asking you questions i suppose i should read your bible to acquire 
some basic knowledge. But there are a view questions i would like to ask you 
right now.

1) Is the hull made in one piece or did you glue two cones together?
2) How did you make the mold?  I suppose you used an internal (male) and an 
external (female) mold. How do you prevent the internal mold from floating 
in the wet concrete? Could you remove the internal mold after the concrete 
had cured and schrunk. Maybe you have some pictures of the building proces.
3) I suppose the viewports are seated in steel rings? Applying steel inserts 
in concrete constructions are probably common practis. I had better start 
reading right now.

Greatings,
Thijs Struijs
