lathe thread-cutting dial 1

[thereg64]

I have an old lathe in the machine shop, which has an indicator dial that has dual numbers. However, the machine is so old no documentation can be found inhouse and/or online. Have tried to contact mfg'r with no avail. Anyone wanna take a shot in breaking the code? Will upload photos tomorrow

Metric and imperial?

lathe will do both, metric and imperial

When in doubt, mark the dial with a marker and use the same position to engage each pass. Does it have a quick change gearbox that is marked with the available pitches, or is it a change gear system?

A photo would speak volumes.

Go over to the local trade school and find the oldest machining teacher you can they will probably know -- if that fails find out who just retired and they will probably consult for a pub lunch.
