I also soak the old bushings with a 5:1 wallpaper-remover: water solution
from a hypo-oiler.  After letting them sit for awhile, I come back and soak
them again.  Then I heat up my key-bushing iron to 200 degrees and using a
tapered broach, insert it into the mortise - basically steaming each bushing
individually. The bushings will then usually come out without too much fuss.

Hi,

I use the method of pre-soaking the keybushings with wallpaper remover and
hot water and after that I just steam the bushings out with a similar hand
held steam device with a small nozzle. Works verry fast and de wood is neat
and clean for the new felt.

Hello....I use the same system...but let them penetrate and soak,,,,while I
do some other job around the shop...an hour later they fall out with very
little digging....and no damage to mortise......
