-clean all residue from underside of ivory to be re-installed
-clean keytop, especially including the front edge of the ivory tail (if 
still in place) Ugly black lines result if you don't.
-make sure dry fit of wafer and ivory results in a flush joint to the 
tail - scraping ivory to eliminate a stair step is not fun. DAMHIK
-soak wafer in water for a few minutes
-position wafer and ivory on key
-place plate on ivory
-tighten with clamp, ensuring that the ivory has not shifted out of position
-recheck ivory position (also in the DAMHIK category)
-using alcohol lamp, and holding key upside down, heat plate almost too 
hot to touch
-let cool
-remove clamp/plate
-trim excess wafer



(Folks, did I forget anything? - it's been a long time since I did it 
this way)

If I had multiple personality disorder, my resume would make more sense.
