[Cob] dirt bags

[Patrick Newberry]

Well the best shap is round.

Basically you put in a compass in the center of your circle. I used a
log/ stump with a wheel from a cart that would spin  360%. This becomes
our measuring tool as you corbelle each row. 

Openings require small value forms.

The box said "Requires WinXP, W2k, or better," and so I installed Linux.

I guess this is not exactly the place to ask for help, as dirtbags 
buildings are not exactly cob, but I can't think of a better place to
ask.

I'm planning to build a dirtbag dome (5m diameter) and I need to know 
what would be the ideal shape (curve) for this kind of corbelled dome. 
Does anyone here have relevant information on this subject?

Thanks in advance,

Nico.
