Hello, and best wishes for 2003,

A friend of mine that is douing pretty good keyboard work said me he have
good result with the steaming method, but he steam oxalic acid (wear a
resirator) to soften the white glue if used.

A thin linen and not too much acid, and he pretend the bushing fall easely.

I personally ordered the special kettle from Renner Germany and it works
good (4 keys at a time) , as the steaming elements are hot enough to soften
the glue.
So I did not use the acid method myself.

Hope that help

Regards

  I have a set of keys (out of a P-22 from one of the practice rooms) in for
key bushings.  My usual method of steaming the old bushings out doesn't seem
to do much.

  Can someone tell me what glue was used to put the original bushings in.
(and what an appropriate solvent would be.)  I've tried steam (ironing a
damp cloth strip over the bushings), wallpaper remover pre-soak, and just
plain picking at them.  Thanks for any help.
