Well, thanks Larry... 8^D
I have'nt done one of those yet, but with the number of bookstores popping up all over the place, I'd be looking for Tex Smith's "How to Chop Tops". It's very informative and even if you are working on an oddball model, most if not all the steps common to a particular roof design will help out with an orphan. Believe it or not, I don't have that book in my 'library' at home, but the local public library does... I've checked it out more than once. Probably under $20 or so from the local bookstore, even if they have to order it, or you may be able to find it at Amazon.com...
