For any odd TPI threading, which are not mention in thread
chart.
For example you want to get 19 TPI. Details of 19 TPI. Threading
is not given on thread chart than select nearest. TPI position from
thread chart and set levers (16), (17) and (18) accordingly on the feed
box. Nearest TPI for 19 TPI threading is 20 TPI. So select levers (16),
(17) and (18) as per 20 TPI. Now we have to calculate gear train for 19
TPI.
Gear train for required TPI = Gear train of selected TPI X Selected TPI
Require TPI
Gear train for 19 TPI = (Gear train of 20 TPI) X (TPI Selected)
(TPI Required)
= 56 X 20
126 19
Means if you set gear train as per 56 X 40 and kept levers (16), (17)
126 38
and (18) as per 20 TPI than you will get 19 TPI. Instead of 20 TPI.
Metric threads 6 mm pitch to 0.375 mm pitch can be cut on
machine. Detail thread chart is given on feed box.
For example you want to get 1.5 mm pitch threading than select
levers (16) on position M & A. Select levers (17) on position C & G
and select lever (18) on position 1. You will get 1.5 mm pitch threading
total 2 types of change gears settings are given to complete entire range
of Metric threads.
For any odd metric threading, which are not mentions in thread
chart.
For example you want to get 0.8 mm pitch than select nearest
pitch position on feed box. Suppose you have select levers (16), (17)
and (18) as per 0.875 mm pitch.
