Keybushings

[John Ross]

Hi Paul,
The best way I have found is, use a Bushmaster, and brass Accu-Cauls
the size of the pins. Both are available from Pianotek.
The Bushmaster tool, inserts the bushing cloth to the correct depth in
the key mortise, and cuts it. I use hide glue, and set the cauls, on
the edge of the glue pot, this heats them, then they are put in place.
When the glue dries, just remove the cauls, and very little easing is
required.

> Since I'm doing a set of keybushings, I thought I'd ask a few
question about the 2 different methods of putting the balance rail
bushings on that I know of. The one I currently use is a lot more
labour intensive and differs from the other method in that I thread
the cloth through the key button and push a "blunt" awl through the
balance rail hole till I can grab the cloth and pull it up. I pull it
till there are two flaps on either side of the button that I glue and
pull into place, fit the caul (straight shape) and trim.
> The other method I know is used by Bill Spurlock amongst others I'm
sure, and involves the use of the one sided caul, working one side
first, then the other. There is no threading through, you do it pretty
much like the front bushings. The method seems so much faster.
> The question I have is, because the shape of the bushings are quite
different, is there a advantage to having the extra bit you get when
you use the thread method? I think Bill has mentioned that he can do
both sets of bushings in an hour, a lot faster than me!
> Also what are some of your methods for making cauls?
