Hi Terry,
I have used the Jaras jig for replacement of a few on a piano, but not a whole set.
The jig seems to work well, in the alignment of the slot to the key movement, and also the centering.

  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??

  Mike

    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.
