If that doesn't work, try using a small propane torch to heat the shaft. The difference in thermal expansion of aluminum and iron will break the bonds between them, allowing you to remove the setscrew..............

Thanks, Red. I’m going to use a good quality lubricant and the heat method to try and break them loose.

I’ll post a follow-up report with pics once I’m done.

Much appreciated.
