Stuck Nut…

Stuck nut.. heat joint and then apply candle wax.. the wax will seep into the joint by capilary action, and act as a lube when you do go to unscrew it. Have a stuck bearing race that you can’t get a 3-jaw puller on? Weld a small bead around the ID of the race.. it will either fall out when cool, or will drop out with minimal force.
