I could see a = possible need to bend the pin if things don't line up right.

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.

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??

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.
