Feed speed

[Howard LewisParticipant @howardlewis46836]

Jason,

Your description of the lathe gearbox is very much as I suspected, plaving variations on the tune set by the changewheels.

As to being self taught, effectively I am.

After leaving the Training School, I did not lay hands on a machine tool for another 25 years or so, and that was only tho pull down the clutch lever on a Cincinatti vertical "To shown the nightshift". Apart from that, during my time in industry, I was a spectator, seeing all sorts of machines from big planers, down to small benchtop lathes, but never laying hands on…

Eventually, I got a fairly well used Myford ML7 and began to awaken memories and get practical experience, (aided by my training notes from Apprentice days ).

having an engineering background, was obviously, a huge help.

But Experience is a good, if sometimes hard, teacher.

Hopefully, you will get your head around setting changewheels for different feed rates and thread pitches. It will become clear as time goes on.

In a few years time, you will be familiar with he lathe and how to use it and on the way to becoming an old hand.

Keep at it.

Howard
