I wish to make a NT30 Arbor with a 1.125" x 12 tpi end to utilize my Myford equipment on my Tom Senior milling machine , am I correct that the angle from the horizontal shoulder to the taper is 80 degrees ?

Thanks..

The Model Engineers Handbook (3rd Ed) gives the taper as 7 in 24 on diameter – doesn't give an angular measurement at all.

That ratio would give about 73.78deg
