I forgot to answer that. I have a Bigfoot saw that will cut that angle. If you don't just keep the saw at 0 degrees and cut the plumb cut. Scribe the center of the plumb cut. Set the saw at 27 and run the table down the center of the plumb cut and that will cit the 63. Keep the saw at 27 and lay the rafter flt and cut the other side of the cheekcut.

Re: 6/12 Roof Pitch


Are you guys saying that you cut all your raftersto the correct bevel no matter what? My saws will go to 50 degrees. Unless it is a large rafter, I will cut the bevel at 50 even if it calls for 63. I have seen some rafters that needed to be a 75 degree bevel. Can't imagine anybody cutting those. When I do an octagon, I will cut the first 8 rafters correctly, then I will bevel some spacers, tack them into place, and then cut the rafter ends with no bevel.

That depends on the circumstances. If I can get the full cut with an 8 1/4 saw, I'll bevel it. If not sometimes I'll head it off or just let it be.

That will work. Just adjust the birdsmouth.

What is the stand on that?
It's the same s the 12/12 Stand at the plateline AFTER you bevel the top of the hip on both sides.

The 12/12 side is 39.22 degrees and the 6/12 side is 11.54 degrees.

Warren,

With the 10" Bigfoot saw cutting up to 73 degrees, making those cuts is just as fast and easy as setting your saw to 45 degrees and cutting a normal hip. Takes 2 seconds.

Re: 6/12 Roof Pitch


Hey do you guys put blocks inbetween the rafters at the tail ends above the wall?? The ends will get soffits. The ceiling height is 8feet 4 1/2in then slopes up too about 10feet 6 1/2in across with the collar joist. Does have a small space for a attic or loft. So the ceiling insulation will be inbetween the roof and the sheetrock for that small 2 foot rise. I will use the air vents stapled up to the plywood before it gets stuffed with insulation so it can breathe. So block it or no??lol Thanks

Block it, yes.

I find this thread curious. Usually everyone will jump all over you because they smell a rat, yet we have given you a pass into the framers club. Very unusual.

I think that is because of the fact that the questions were well thought out and intelligently asked, with no mention of how much to charge.

Re: 6/12 Roof Pitch


This is not for a customer its part of my house. So definetly dont need a price to charge. I never charge when doing this type of work. When I do it its helping friends or my personal projects. As for work I do do and get paid hourly is through the nycdcc. We never work on residentail houses. All trade shows and commercial building. Thanks guys Shouldnt I leave some space at the top for air to circulate from the soffits to the ridge vent? Maybe use a 2x4 for blocking leaving a 1in space at the top??

You could put some V-notches or drill holes. We used bird blocks in Seattle. They had 3-2" holes with 1/4" screen stapled from the back.

Or set youir heel height to 4-1/2" and use 2x4's to get your 1" air gap

Trusses for a 16' wide garage? Waiting a few days for them? You can have this simple roof stick framed an sheathed in half a day while you wait for your trusses.

Ditto

I need to send you some program routines that will convert all of your decimal answers into Feet - Inches - Sixteenths

It makes it nice on the brain.

I know the degree of a 6/12 pitch is 26.50. But I dont have the span of the rafters. Im using 2x8 roof rafters. Any info would be greatly apprectiated. Thanks

Just a question...why are you framing the roof by hand instead of using engineered trusses? Is it a matter of cost efficiency? What is the width of the garage?
