Thanks guys,

I have started a new folder in my documents called "joe b genius". I am attempting to print and lock away in my file cabinet all of those invaluable formulas. I must say that I am trying to decipher some of it and will continue to do so. Much thanks to you sir.

As far as dimensions nothing is set. The sticks for the arched braces if cut out of straight timber would be 14". The drawing is incomplete. As EH commented their needs to be a joint on the centerline of the truss at the arch, and it seems after examining that the rafters are not big enough either as far as scale in the drawing. Below seems better

8" collar tie
10" rafters
8" posts
10" tie beam (all dimension are the seen faces)

10/12

Hey Joe, I'll let you know if I can work my way through it.

Thanks, mo
