If you were framing a gazebo roof, would you set the 4 common rafters 1st or the 4 hip rafters? why? any other ideas or suggestions?
I already have the cuts figured out, I think(for some reason I remembered the hips being X over a 13″ run vs 17″ for regular hip/vals), but just thinking through the order of events.

Only 4 hips? The one gazeebo I built had 8.

octagon shape (which I didn't define inthe OP) and you're right, typo in the OP, 8 hips
I would always set the hip rafters first, regarless how many. Must be a really small gazeebo to only have four of each

John,
That's correct. Whatever the pitch is over 13 for the Octagon hips.
We have always set the Hip rafters first.Gazebo: 6/12 Slopes and Regular Octagon Footprint

Thanks Joe, and everybody else.
After I started sketching it out I realized that I'm going to have to run the commons into a header spanned betwen the hips. So the answer to my own quesion is to set the hips first.
Now if I could only get Sketchup to work on this Vista laptop...
Happy Friday
John,I don't understand the header part.Do you mean a post or a 8 sided header all the way around? What is the width or side lengths, and what is the pitch?Is it A or B?Joe Carola
Similar to B , Joe. I'm figuring on setting up the hips 1st meeting at the peak. Move down a bit and span a header between the hips to dead end a shortend common rafter. Whaddaya think? I'm home now and off the laptop so I'll build something up in Sketchup & post my idea of the soution.
To describe it: ocatagon, with each side length @ 74.5". Octagon "diameter" is 15'. Pitch will be 7/12. ...and a twist: going to be intersecting the corner of a porch roof pitched at 4/12. Gazebo roof will be sitting on 10" diam columns so I'll have to figure something for wind lift resistance (hello Simpsons) . The details for what the whole thing will be sitting on haven't yet worked out but it won't be a slab. Deck probably on posts, maybe columns of cmus (rather not), or poured crete columns @ the corerns or all crete walls ($$$). I know what'll be cheapest (posts) but not sure if it'll be the best. Columns on top of the decking and then 2x headers on top of the columns for the roof to set on. Did I mention the porch facia? I have to match the facia heights which I think I can do by adjusting the headers vert height. Depending on how clean I can make it, might propose leaving it open (no ceiling) and paint. May use rods in lieu of ceiling rafters for the outward resistance.
John,Is it like this? If so I've done that before with just a single header.Joe Carola
You got it, Joe. I'll post some pics from SU when I get it laid out.
John,Since it's a Gazebo and the rafters I assume are exposed, I wouldn't put that header in. I would cut all the jacks with the plumb cuts getting cut with a 67.5° saw setting nailed along side the hips. It would definitely look better that way.Are the rafters 16" or 24" centers?Joe Carola
Wow you're up making dust early, Joe.
Spacing is 16, local amendments prohibit 24s w/out engineering stamp. Since it's a porch it may slip by at 24's but I've never thought to challenge it. Right now the plan has a header which will be covered with beadboard or similar as well as be a support for framing to hang a ceiling fan. I offset the commons & jacks to make the spacing more appealing, will be a little wide at the tails of the hips and above the headers near the peak, shouldn't be an issue though. I'll have the intersecting 4/12 porch roof done soon I hope.
Nice coincidence, make a compalint re: SU not supporting Windows Vista and what update do I find when opening SU this AM? The recognize Vista now, we'll see, DLing right now.

Wonder if I could just upload the SU file? Ever doen that?

Here's what I came up with.

To find the angles of the valley rafters between the 4/12 and the 7/12 roofs I laid out a couple of the porch roof 4/12 commons and laid plywood on the gazebo and 1 on the 4/12. Sliding the sheet on the 4/12 into the gazebo showed the intersection clearly. Cut that sheet to follow the line of the intersection and then moved clear so I could project the locations of the angles onto 2 intersecting planes.
