Try this
Feed gears, feed/.0375 =X .020/.0375 = .533333 38/60 X 48/57 = .533333
Index gears 12 Tooth 15/N = 15/12 = 1.25 45/54 X 63/42 = 1.25
Index gears 75 Tooth 15/n = 15/75 = .20000 26/65 X 30/60 = .2000

Iím assuming normal Pitch Diameter.

Lead Gears 12 Tooth Pitch Diameter 1.939472
Lead at P.D. 13 Deg. HA = 26.39182 15/26.39182 = .568357923 34/67 X 56/30 = .568357923

Lead Gears 75 Tooth Pitch Diameter 12.12170
Lead at P.D. 13 Deg. HA 164.9489 15/164.9489 = .090937 21/70 X 20/66 = 0.090909 (error of .000027)

Iím not sure of your hob info but your setting angle will be different for left and right hand gears.
