Frozen Shaft on 100# Fairbanks Hammer

For heating the journals, you might try heat tape that is sold in the plumbing isle at home improvement stores. Not sure how much heat you can muster from such a thing but it would allow heating both journals evenly. Paired with penetrating oil , and given time, they may help get lubrication deep where it needs to be. I doubt you get much expansion from a 150-190 degree heater, but it would help some. These parts were a running fit, but are full of rust and dirt. Wash that out and you should be good.

Heat tape is thermostatically controlled and only comes on below freezing. Good thought but . . .

If you just need low heat like that a couple of heating pads would do.

A pair of engine block heaters might do the job. I never had any pipe heaters that had such controls- I am probably just buying the cheap ones though

Pipe heaters are thermostatically controlled, there is no reason to run power if the water in the pipe can't freeze. Unless you're taking about something else.

You can buy magnetic engine heaters, stick them on plug them in and they get pretty warm. Might be just the ticket, especially if you pack the shaft with a little dry ice.

Did you ever get the shaft freed up?
