I had to remove the handle from a shower valve yesterday. Although I was able to get the set screw backed out enough to pull the handle, the screw became stuck and wouldn't move in either direction. A replacement handle is 25 bucks, so I decided to see if I could salvage the old handle.
First off I filled the handle with Kroil and let it sit for an hour. No difference.
I'd never tried applying heat to pot metal before, but I figured worst case I'd have a pool of molten zinc on my workbench. I put my smallest brazing tip on my oxyacetylene torch, placed the lever in the vise using padded jaws, and started heating the lever hub. After a couple of minutes of carefully heating the hub and trying to turn the screw it came free. The stainless screw was still in good shape so I just dipped it in grease and put it back in. The lever looks good as new and the chrome plating doesn't appear to be damaged at all. I'm sure I'll use this technique again in the future.
