Procan,
I borrowed Fishcop's idea and am building an Octisserie for my project. I am in the States (Florida) and sketched it up in a CAD program using Fishcop's dimensions but then converted to English units, primarily because the materials available here are all in English units. I have a drawing created but it is not quite ready for primetime as there are a few things I figured I would build in place first, then get measurements and update my drawing. My intention is to post my drawing in my build thread here when it is ready:

I finished the forward octagon yesterday. The below picture is sans gussets at the top and the studs on which the connecting bars attach. I just used scraps of 1/8" plate for my gussets but didn't take a follow up picture when I was done. I have spent less than $250 on materials so far and think I will be under $300 including consumables when all is said and done.
