mactec54, That's true I missed that, you could use oil or another coolant though. I know with mine, there was no way regular tools would have worked the first time it was rebuilt. Years of being run hot in a wood shop production environment, had locked everything together to a crazy degree. In my case, even the heat and cool wouldn't work first time, as I tried every trick in the book. Eventually after heating and cooling a number of times over an hour or two; using wax each time to cool the joint, it came off. I have had to re-machine most of the spindle as a result to get it back in shape... In retrospect it wasn't worth the effort and I should have picked a better candidate for rebuilding!
