Odd angle fitting from a 45 elbow - Contractor Talk - Professional Construction and Remodeling Forum

Hello, I'm fairly new to pipefitting. I've just passed my NCCER cert. test. But I've still got alot to learn. Today I was asked how to figure out the ordinates and cuts to make a 29.6 degree angle out of an existing 45.

The basic layout is not a problem, it's simple math. The trouble I'm having is figuring out the best way to find my centerline on each side of the elbow. I have a few ideas and theories but figured I'd put the question out here and see if one of the old veteran pipefitters may have a simplified method.

FYI I'm dealing with schd 40, 36" cs pipe/fittings

Thank you in advance for any ideas.

I know this is an old question, but if I'm reading you right you just need to quarter the pipe?

Level the fitting, find top dead center with a center finder. You can quarter the pipe off that mark with ticker tape.
Or if the angle will allow just use the center finder.
