Good replies so far. I have found that if the original glue was hide, just water and a couple hours will have them falling out (I add a little alcohol at first so that the water can wick into the felt). I did a set of Baldwin keys recently with the bushings glued in with some kind of white glue. I soaked them with water for some hours (recollection is four to six hours) and some were kinda loose. I hit them with the soldering iron and brass caul inserted into the mortise and all popped out very easily and quickly. I did no post-removal cleaning of the mortise. I then size the mortise with Spurlock mortise sizing cauls and allow an overnight dry. Next day - swab down bare mortises with thin hot hide glue (as Bill Spurlock instructs) and then install new bushings with hot hide glue. I have not had the need to use any kind of retarder. I put glue on a length of bushing material and do about three bushings before reloading with glue. Works for me.

Tomorrows job will be on a mid 80's Young -Chang and I'm not sure what type glue was used. I searched the archives and read of Wallpaper remover,steam , or soaking bushings with an ammonia solution. I read that the wallpaper remover can inhibit adhesion on rebush. Any tips appreciated. Part 2. Pvc-E ? For rebush? Back to the future with animal hide glue? I confess that my glue pot has spider webs in it I'll be dead when these have to be removed again, but I'm leaning toward hide glue because I care about the next tech. That's just the kind of guy I am. Should I add urea to the mix? The ratio suggested was ½ tsp to 1 tablespoon granules. Joe Garrett, Don't get mad, but what's the word on PVC-E? Will I be creating a problem for the aforementioned future tech, or can it be dissolved easily? Awaiting advice with appreciation Tom Driscoll P.S. I don't look to the archives as often as I should, but that's where Newton lives ,still helping us along our way.
