   I can't see where it would make a difference to the jack spacing.

   I'm certainly no expert at this so I am interested in the answer.

   I have framed several hip roofs though. My very first solo frame job included a hip, and though I was expecting my mentor to show; he did not and I did ok.

   Unless I am missing something or entirely wrong, shouldn't there be a common in between the 2 hips??

   It would be in line with and butt to the common ridge. The 2 hips then intersect between it and the last common on either side.

   No expert here ether but logic would seem to indicate the diagram on the right, the 'imaginary' intersection of the ridges would be 'on-center'.

   I have always done them as shown on the left. I line up my rafters with the wall studs.

   Thinking regardless of rafter spacing, diagram on left looks a little more ' oad bearing' where the hips meet the main.

   Gene, the wording of your question indicates some concern about jack spacing, but it's not entirely clear of your goal.

   Just for you information, both drawings could serve as a competent model. The framer will have to make adjustments on the rafter based on the centerlines and each method creates some minor differences.

   That said, I'll offer this. I think I know what you want to accomplish with the jack spacing but again, there are an infinite amount of possibilities and none are "right" or "wrong".

   You probably want to pencil in a common that is directly in line with the ridge. Normally, most framers will run the common all the way to the ridge, but it isn't necessary.  The primary reason that the common should be in line with the ridge is purely asthetic...and I think that's what your looking for. By lining up the common with the ridge, it automatically causes the first jacks to shake hands in a uniform manner.

   Just because you can, doesn't mean you should!

   Warning! Be cautious when taking any framing advice from me. There are some in here who think I'm a hackmeister...they might be right! Of course, they might be wrong too!
