How to build a bay roof

- This is a long video and if it seems complicated, it’s because it really is. If it seems like no thought when into the organization or filming, that’s because there wasn’t. I’m just recording on the fly and if it was my job to make videos I’m sure I could make this much more digestible. But if you have done any rafter cutting at all, you should be able to pick up a few helpful ideas. Even though bay roofs are fairly common, they’re rarely built correctly and usually just some framer winging it. And that’s fine, but here’s an in depth look. I tried to show different options at several points in the video. Lots of the geometry is drawn on osb which I know is hard to see on video. Apologies there. Maybe I’ll do a short video just on the drawling aspect. But anyhow, lots of concepts here and once you understand how to find these numbers much of the tedious drawing can be skipped and worked out in your head on a construction calculator. Good luck, and comment if you have questions.
Here’s a link to the book that taught me projective geometry used in this video

This is next level craftsmanship! You're not just a carpenter but an artist and mathematician. I love this! I hope you're getting paid what you're worth. P.S. incredible teacher who takes pride in his work also. Rare indeed! Skip McCain
One of the best layouts I've seen, glad to see you used backing cuts .How ever if you're not using a closed soffit I double bevel vertical seat cuts on hips to accommodate finished freeze blocks. 40 years ago I learned

thank you for sharing
This was so helpful, thanks for taking the time to make this!
clear as mud.good job.
Well Done!!
Great video!
These videos kickass thanks
I think I hv watched this 4 times total? I believe I got it theoretically and I even understand the geometry behind the arcs ! Being a finish carpenter this just fascinates me ; so I am building a storage shed ( why buy one when you can spend more on materials & build one?) to store trim in & certain tools ! Now I am certain I am cutting a small roof on it and cutting a small bump out window and then cutting this over it!
My dad is a retired builder and I am pretty sure he thinks I am nuts? ( oh and I am grabbing that book also).
I too am building a shed, and I too will make it more complicated than necessary. Best of luck and feel free to ask questions, if you think I can help!
@@Redoakcarpentry much appreciated I am punching out a bunch of cabinets and when done ; I am starting on it!
Excellent videos! Hoping you’ll do a bay window curved roof video. I’d imagine it’s a combination of this and your curved video. But…
Just came across your video and to me its "Gold Dust" I will check out this book also,
Thank you
Awesome video full of great information. Thank you! Can you recommend a book where it shows you all the ways you used to draw out the backing angles and swinging of the arcs for angles?
Yes! I added a link to it in the description. Thank you for watching!

Thanks.
This is definitely a great video and it’s really helping me. However I got lost at about 9:45 when you mention having the hip rafter drawn out. I watched through the video but I just don’t understand those lines and where they came from. Are you able to explain? 9:45
It’s a bit of projective geometry, it is confusing and the plywood doesn’t really help with clarity. You can buy this book www.raftertools.com/book.html
I’m sorry but that was my best attempt to explain it lol. Once you draw out the hip rafter triangle, the next line (line A) is arbitrary so long as it is square to the hip and projected to the plate line. The next two lines originate from the intersection of the hip and line A.
12 pitch in all sides? With bicepting the angle
I just cut the common rafters stack it front and side and pull a tape for the hip.
I’ve done that many times as well, eventually I liked to know what’s going on tho and I enjoy knowing how to figure it all out. Do you measure diagonally? Like from thd top of the hip to the birds mouth?
2:58 instead of pivoting around a nail, you could line up the tongue with the perimeter line and then mark 90° up the blade. Ditto for a second blade line or mirror image coordinate. Of course the corner of the square is facing away from the 135° bay hip angle as you have your square. Guessing but the most you could be from the bay's hip angle is 14" along the tongue or the 2 blade lines won't intersect each other without extending the two lines.
Yup that’s true. I only used this particular method because I wanted people to understand how to bicect an angle, because it’s useful in other areas of framing and very often you have no choice but to swing an arc.
@@Redoakcarpentry btw, I liked how you took the effort to back the top edge of the hip, ledger, etc. ★★★★★
