NPT thread dims? How do you program for CNC?

NPT thread dims? Edit: Chart Added

I recently had to do a quick one off job cutting some external 1 1/4" NPT threads in some plastic. Rather than getting our programmer to do it offline, I figured I can just hand write a simple program at the machine.

Since it was plastic, I figured a quick turning path to produce the taper, and then thread it. I then spent an hour scratching my head and trying to calculate what diameters to turn the material to and what coordinates to program the threading too. The Machinery's Handbook gave me pitch diameters and I faked it from there until it fit since it wasn't a critical part.

It got me thinking, there must be an easier way to figure this out. How do you guys do it? It's there a chart our there or formula I can use to figure out my programing points? I hate spending an hour doing calculations just to cut some simple pipe threads. All our pipe thread is usually programmed offline so I've never really had to do with it before.

Any help is greatly appreciated.
