  • annoying machine marks problem solved

    I posted on a problem I had some months back where I was getting a slight groove like coarse threading when turning an OD. It didn't show up when boring or facing. On a hunch it check the drive belts, two in tandem and they where a bit slack so I loosened the motor mounts and snugged them up. The marks are gone. The lathe does start with a bit of a bump now, maybe no slack to absorb the hard start?

    Any way the work finish is now fine. Hope this helps someone else.
    The shortest distance between two points is a circle of infinite diameter.
