Deb -
I love 'dedicated set-ups'. Allows you to party late (the old days) and still do a decent job. Just kidding, really, as, set up or not, you're using a router and are fond of your fingers and all.
Alan -
Beyond saying that I prefer hot-hide, I feel somewhat stupid, in that I don't do this quite often enough to codify the ratios, which, given the variables of hide glue itself, might not be possible. My preferance is based more on bias and assumption than on rigorous experimentation. I assume that hide glue will cure harder than white glue. I feel a bit more in control of the dilution. As I'm thinning it, I test by rubbing between my fingers and judging the remaining adheasion. I make the mix as warm as I can. If it crusts up as I apply it, I suspect it needs more water.
Note, I could have said "thin to taste" but then I'd need a 'glue-licking' dog like Terry Farrell has.

David, I knew I should have kept my mouth shut! Currently using white birch. A hardwood but not noisy like maple can be. A soft hardwood? Grain orientation matching the keystick. We aim for same depth. It helps that I have a dedicated set up for the job. Having the keyframe on hand is essential. No video(!) but I'll try to remember to take some pics tomorrow.
Yes, for one or two minor pulley keys I would glue size.

And who will be playing the technician in the soon-to-be-released video? :)
what kind of wood do you use for inserts? do you match the thickness of the insert with the depth of cut or is it oversized and planed down?
Do you EVER size holes?
I like Debra's method, but, since I'll probably not immediately adopt it (soon), I'll continue aggressively glue-sizing holes -
- pre-clean holes with alcohol so gluesize gets absorbed more redily
- steam
- apply sizing - should have thin enough viscosity to be absorbed but enough glue to solidify
- when dry you can force onto pin and allow to shape; arrowhead tool; Pianotek KCS tool

Hi,
We use a front and rear offset register tool. It leaves small indents on the underside of the keystick front and back of the balance hole while establishing the corrected hole placement. Then router remove 3/4 inch centered on old hole. Glue in wood inset, use register tool on underside and as a guide for drilling the new hole. Just did an entire keyset for a local tech.

What's everyone's favorite pulley key repair technique currently?
