Included angle of lathe centre
WebNov 22, 2007 · Another way to do it is to use the formula Tan 1/2A = TPF/24 where A is the included angle of the taper. Alternate formula is Tan 1/2A = TPI/2. Your problem has a .250 total taper over 2.5 inches so .25/2.5= .1 TPI. So, Tan 1/2A = .1/2 = .05 On my calculator then Shift Tan = 2.862 degrees which converts to 2 degree 51 minutes 44 seconds.
