    Wishful thinking - wanted 8" 1hp low speed grinder

    One of the good things about that Magnum (KMS) 8" is that the motor isn't too bulky. On my 6", the workpiece starts to hit the motor housing in a lot of situations, especially as the wheels wear down a bit. IMO, a design with longer shafts so that the wheels were farther from the motor would be...

    Wishful thinking - wanted 8" 1hp low speed grinder

    How much pressure are you putting on the tool? Is the wheel a good quality one? I got Norton white wheels for the 8" and I can touch up the metal lathe .040" parting blade in pretty controlled way. But those white wheels are soft and I don't think they would last long for 'general grinding' -...

    Wishful thinking - wanted 8" 1hp low speed grinder

    I have that grinder - bought earlier this year. It spins round and round, but otherwise not too impressive. Typical 'offshore' rests and guards which are pretty much in the cheap 'afterthought' category, IMO. Without that special personal relationship with the local KMS that @David_R8 has, I...

    Line Noise Suppression Capacitor?

    If the original part is an X2 'safety cap', it's best to replace it with the same type.

    Comox? Don't feel too bad- those Craftsman 618(?) machines could be fun, but definitely have limitations, from what I read.... Another 618 came and went in the Victoria listings a little while ago -@$600 - so this one was a much more sensible bargain.

    Do these potentiometer numbers mean anything to anyone?

    Thanks for that clarification. I don't want to cause confusion about 'direction'; the rectifier comes 'after' the controller...it's 110VAC->'SCR' controller->bridge rectifier->motor

    Do these potentiometer numbers mean anything to anyone?

    Maybe you are buying too-good quality.. :) Here's mine: https://www.aliexpress.com/item/1005002074105818.html? I used the same type of controller on my drill press with the treadmill motor, but on that one I used a pot which started the spindle at about 100RPM when it was full CCW. That's about...

    Do these potentiometer numbers mean anything to anyone?

    It just ain't so...here's the SCR motor controller +bridge rectifier controlling the DC motor on my 7x14 Microlux lathe:
