Thanks for all the help from this forum.
I think I will build a 4V next so I dont have to pester colin for calculations for a flat base.
PS. Make sure you give yourself a large margin of error on sewing the canvass. I made it far to tight and it made sewing quite difficult - despite its good fit.

I don`t envy you all that sewing!
Looks like you have plenty of space there for quite a few domes.
My latest project is also 4v but it`s not a hemisphere.. that`d be too easy ;)
Awesome job, and an amazing group of young people. Outstanding!!!
I`ve been asked to build a canvas covered dome and was wondering where you bought your canvas from, also how much it was per sq yd/or sq/m? The only place i`ve found so far is up in Dundee :)
