38°, is that what you are using for the common rafters?
Yes Sir 38 degrees is the common rafters that I'm using.

Yes Sir 38 degrees is the common rafters that I'm using.
Then your hips/corners will be 28.92° or 29°.Joe Carola
May I ask how you figured out the angle?
May I ask how you figured out the angle?
He said that he was using a 38° angle for the commons and probably scribing it with a speedsquare. 38° is roughly 9-3/8/12 pitch. I used my Construction Master Calculator. There are many ways to do it.
If he wants to just work in degrees, he can do this.
38 [Pit] [Pit] [=] [Rise] [Hip] [Hip] = 28.92°
That took 5 seconds.
But, he doesn't even have to do any math when using the speedsquare. He has his speedsquare set at 38°. Look at the commonnumbers on the speedsquare and it reads roughly 9-3/8".
So now you know that the speedsquare tells you that the pitch is 9-3/8".So now just set the hip part of the speedsquare at 9-3/8" and that's your hip angle plumbcuts.
If he wants to use a framing square and the hips are running at 45°, all he has to do is this.
38 [Pit] [Pit] = 9-3/8" (9-3/8 over 12 on Framing Square for Common Rafters)
Now, all you do is just hold 9-/38" over 17 for the hips.
Hope this makes sense.
