My Jet 1024 can do SAE and metric threading. It can do .75 mm pitch,
but not .7. But the M4 standard pitch is .7!

1. Why in the world wasn't this lathe designed to do .7? There's only 4
or 5 pitches that one needs 99% of the time and .7 is one of them. The
lathe will do about 20 different metric pitches, but not one that is
needed! Unless ...

2. Is .75 close enough?

Thanks,
Bob
