ML7 : To convert, or not...

Not sure what you mean by this

easier if you can get a twin-sensor coupler with a pitch smaller than the hole gap space

re the 64 pp rev you you want it for threading then you won't be running the spindle fast. I think I have tested it at about 600 rpm. 64 was just the number I drew the disc in cad. you could also just use one sensor on the disc and another on a tooth some where as long as it is 1:1 with the spindle.

When I change the motor I might have a go at CSS (constant surface speed) with a VFD for the fun of it.

With the 3 sensors like mine it could do rigid tapping. Although I have never done it on the lathe.

Edit re the mpg's I used the same mpg's between the mill and the lathe with the same control box with 5 drives in it and one mesa card (using only one machine at a time)
