	Eliot, hire a veteran technician to show you how to do the job.
You'll be glad you did. From your questions, it seems that you are in over
your head.

	It *is* advanced piano technology. If you don't understand the
touchweight implications of replacing hammers, and aren't skilled in
reglulating and voicing, you have no business replacing hammers. I've seen
more botched hammer jobs, resulting in more unplayable pianos, than I care
to contemplate....
	8 hours to do what? To do the whole job, including regulation and
voicing, I would consider 8 hours quite fast.

	This is not a method of removing hammers. It is a method for
removing broken hammer shanks in the field.

	Do what in 3 hours? Remove the hammers? Remove and replace the
hammers? For hammer removal only, 3 hours would be incredibly slow. For
removal and replacement, incredibly fast.

	Schaff has a jig for vertical hammers which looks very
complicated. I've never tried it. For grands, I use Spurlock's jig.
