What a beautiful lathe ! Probably much newer than my 1948 myford 7

[@prof-rieg]

Indeed, I like it very much.

[@prof-rieg]

Well, this ML7-R was made in 1973 according to the serial number.

[@andrewsmith8388]

@@prof-rieg I bought my lathe 2 years ago to learn about machining. Its age stops me from modifying it. It was one of first 2000 made of a production run 130,000... if I saw a super 7 or ml7r I would buy it and keep the ml7 original

[@andrewsmith8388]

But options are limited in New Zealand !

[@prof-rieg]

@@andrewsmith8388 but you i.e. New Zealand are a member of the Commonwealth. It should be not to difficult to buy one in Great Britain.

You count how many times the magnets trigger the hall in one seconds correct? But in low speed it's fluttering between 30 40 rpm. If I reduce the time will the reading be better?

[@prof-rieg]

@@devilvortex1 no, you would need more magnets.

This is a great home project. Do you have a link for the arduino program and necessary libraries available?

[@prof-rieg]

Yes, I've added a link in the video description. Please check it.
