Ok as by my name you can figure that I build sheds for a living, since I usally build three a day I don't have time to mess around! So I cut "EVERYTHING" in the shop and bring it to the job site and wack it together! My pet peev is jack rafters,, everthing I cut ie:commons, hips, ridge beam fits bang on, even the legnth of my jacks are bang on the only problem is that I can't seem to get a perfect fit of my jacks to the hip ex: 10x12 shed 5/12 pitch, I cut the commons at a 5/12 the hips at a 5/17 but what angle is the jack suposed to be? I cut a 45* cheek cut but 5/12 and 5/17 do not fit nice against the hip! I see on my framing square "SIDE CUT LEGNTH OF JACK RAFTER" IS 11.06 so I tried 5/11.06 and it seemed to fit rather well but is that the right way to read the square? For example on a 6/12 pitch under "SIDE CUT LEGNTH OF JACK RAFTER" it is 10.75 so on a 6/12 should I use 6/10.75 as my jack angle??? Would apreciate some help if anyone can thanks.
