I am interested in finding a book I used to have.
the book was in paperback form and went into great depth about the math for roof framing. in the back of the book there was a chart on hove to cut ovals in sheathing of different pitches and for different pipe sizes.
the book also provided formulas for finding the angle and bevel cuts on fascia.
I have a 6/12 roof with square cut rafter tails. There are a lot of hips @ 45 and 90 degrees can anyone help me out on finding angle and bevel cuts without scribing and easing into it, I also remember doing it on my construction master calc by doing thee triangles
Hi Pete - I saw your previous thread - 82670.1
Lots of responses, but I didn't see any thanks or replies from you, and it looks like most of the replies to you are still unread. I posted a method of finding the roof angles, including the fascia miters, on a hip roof with square-cut rafter tails. Let me know if you need help understanding it.

Pete, I have seen a couple of old reference books over the years that address your situation, sorry I don't remember the names of authors or titles. also I think a good math teacher could solve the problem.
taken from "A roof cutters secrets" by Will Holladay , chart 7, page 303, reprinted with permission from "The Rafter Book" courtesy of David McIntire,
if a roof pitch is 6/12, the side cut line (framing square setting) is 6 13/16 x 24, and the miter angle (saw bevel setting) is 39 1/4 degrees.
I too wondered about the lack of responses but it's possible that the thread has ... disappeared. I've had this happen on a few occasions to threads and/or posts.Joe Bartok
My guess is that he's new to the forum, and hasn't really figured out just how it works. He posts his question, then can't find it, so he posts again. I notice the replies in this thread are also unread by the original poster. I'd write an explanation, but I'm doubtful he'll reappear in this thread!"Down these mean streets a man must go who is not himself mean, who is neither tarnished nor afraid...He must be, to use a rather weathered phrase, a man of honor, by instinct, by inevitability, without thought of it, and certainly without saying it." - Raymond Chandler
I have had threads, often threads I have subscibed to, come up as "Discussion does not exist". Do they disappear into a quantum wormhole into an alternate parallel reality, or what???? :)Joe Bartok
