I read somewhere about a technique involving sulfuric acid dripped into the oil hole to dissolve the pot metal. The acid is not supposed to bother paint or cast iron if I remember correctly.

Who has the best idea for freeing up a frozen bearing on an Edison Home Model D without messing up the mandrel, the mandrel shaft, gearing, etc.? I have asked this before, and have received all sorts of answers--from heating with a blow torch to freezing in the freezer. I have a tough one right now that I don't want to mess up. How about it friends? Who can come up with the best way to get that bearing out? Thanks for any suggestions!
