Here is a picture of a one inch sander with a clamped board behind using =
short ends of angle brackets to serve as a stop.  Adjust position with a =
straight edge against the belt and clamp with a couple of squeeze =
clamps.

Now the second picture shows how you can just zip off the overhang =
without taking a bunch of wood off the key.  First time I tried this =
without the stop, the dam key almost disappeared.  Use 35 or 50 grit =
belts.  Works fast.

  Terry,

  David Betts gave a class on this (in Nashville?).    Can't find the =
handout.   For each section of keys, cut the new buttons to the average =
angle and wider than the key.  Installation is in the keyframe in two =
batches,  every other key so you have clearance in between.   Or three =
batches, if you want to do the blacks separate from the whites.  Keys =
resting on wooden bars so they are level and at the right height.   May =
have to remove front punchings.  Straight edge on top of keys along =
front of buttons for alignment, both angular and front-to-back.  =
Side-to-side alignment is provided by the balance rail pin.  No clamps =
required:  Tite-bond, hold in place for count of 7, move on.   When =
fully cured, trim flush to key with band saw, finish with sandpaper =
block.  2 hours sounds optimistic, would you settle for 4 to 5?  Clear =
as mud??

    Subject: Key Button Installation


    I need to install new key buttons on 88 keys. Never done it before. =
I have the Journals on CD, but have never been able to do a search on =
them. I found an old article by Fern Henry that described a very simple =
method/jig to do this task. The few articles I have found suggest that =
many techs prefer to replace button rather than rebush and complete the =
task in about two hours. In two hours, following a modified Fern Henry =
method, I have eight keys done. I've got 80 to go. At this pace it will =
take me the better part of a week to install a set of key buttons. Is =
anyone aware of a good article in the PTG Journal that describes the =
procedure? I see the Jaras Key Button jig in the Schaff catalog - anyone =
have an opinion on that? Anyone got any other =
favorite/excellent-result/fast method of replacing key buttons?

    Thanks for any input.

    Terry Farrell
