i'm having trouble modeling NPT based threads on my model. I have to design it based on a 1" thread. I dont know how to get it going on solidworks via hole wizard. I've tried but it doesent work.

 

I tapered my cylinder to 1.79 degrees and want to use the outside diameter to place the threads. The specs I need to follow are as follows:

 

Pipe: 1"

Threads/in " 11.5

Pipe Diam: 1.315

Tap Drill : 1-5/32

Pitch : 0.08696

Pitch Diameter @ beginning of thread: 1.213

as you can see from my picture the bottom cylinder is already tapered to the NPT standard of 1.79 degrees but not sure how I can go from here..any help would be greatly appreciated!!
