    I do you heat the collar with a plasma? I might use this process if it is easier then a oxy/ace torch or rosebud or tiger torch.

    Cut off the outer race with whatever, then cut the inner race almost through in a few spots and it will pop off. I have also used a cutting torch, and a plasma to scarf off the race. Once the inner race get good and hot in one spot it will generally come off easily. Want to work fast so as to not put too much heat into the spindle/shaft.

    Easier and safer than anything else I've tryed and it doesn't scar the $$ shaft. Gotta be on the lookout for grease fires though

    But how do you heat the collar with the plasma? I'd like to know, if it's easier to heat with it I might try it next time I have to do it. I didn't know you could heat steel with a plasma torch.

    Just stike the arc and move the plasma head around the collar, heats it up pretty fast.

    I'm going to try this next time, beats gouging it out, would be good on small collar.

    Thank you for the hint.

    I don't know how long the tip would last, they seem to burn quickly.
