Table Til. Giving basic gear ratios for threads/inch from a lead

•Denotes ratios with an error of less than 0.1%

None have an error of more than 0.4%.

To check the pitch given by inch measure from the gearing shown:

For a leadscrew of 3.0 mm. pitch, the same ratios can be converted:-

(1) If possible halve the denominator.

(2) If (1) is not possible, let the denominator stand, and double the numerator.

Note: Threads/inch cut from a leadscrew of 3.0 mm pitch should not be less than 4 (four), and this can severely strain a small lathe.
