SUCCESS!!!!
Here's the finished part.
OD is 2" NPT, inside thread is a screwball Medical fitting thread, 1-1/16"-16.
I was able to threadmill both sides.
I used the NPT Thread mill Wizard from Machinist Toolbox (Thanks for the link HOSS).
I also had to put ALOT of cutter Comp on it. ( +.140) Glad I started big!
I wonder if I should charge the Hospital $20,000 , since one aspirin in the Emergency Room costs $500.
