Stuck Ferrite slugs

[jeyurkon]

Any suggestions on how to adjust frozen ferrite slugs? It appears that the wax has melted and glued the slugs to the coil forms. I have the proper alignment tools. I learned the hard way years ago not to improvise here.

Should I try a hot air gun or just let the set run until things get hot enough to free up, if ever?

I might not need to do an alignment, but wanted to start thinking about it in case I do need one.
