    Re: Unbranded DRO scales like iGage

    TNX Jeff for the info. Looks like I can use a Dremel cutoff wheel or take 2 pieces of wood and clamp (lightly) the scale in between and use a hacksaw to cut the scale.
    The wood being clamped would...

    Unbranded DRO scales like iGage

    I have read on some eBay ad's on these unbranded iGage DRO scales (Shahe made?) that you can cut the scale to custom lengths.
    Is this true? If so what is the best way to cut them? (fine tooth...

    Re: CB1220XL spindle motor upgrade

    Yes I see there is a difference in the KBelectronics controllers. The one I originally bought is a SCR type and should have been the PWM and then maybe
    the motor might have run much cooler. I have...

    Re: CB1220XL spindle motor upgrade

    Thanks for the info JD, but for $995 I think I will keep changing the belts. For that price it isn't worth it for me on a lathe
    that is hobbyist at best, need a cheaper solution.

    12,700 steps per inch.
    But need to increase the velocity from where I had decreased it. A bit too slow. I don't have
    the acceleration or velocity numbers handy.
