Thanks Fred, the ironing sure saves work later.

The capstans will still need some raising, and sometimes it's a timesaver to
adjust one with the stack on, count the turns, then remove the stack and
raise all the capstans in bulk fashion.

(Is this the place to confess I used to remove vertical keys, hold them by
the dowel and swing them (once, twice) around my head for bulk adjustment?
Really depends where the customer was at the time ;>)

Teflon? Yes, I'm leaning towards;

1.) Clean/polish/wet-lubes on hard surfaces "only"
(metal/wood, capstans, key-pins, bridge-tops, jack-tenders, etc.)

2.) Vacuum/iron/dry-teflon "only" for the cloth surfaces (includes key &
guide-rail bushings, lifter felts, etc.)

BTW, for trimming bolster cloth (encouraging to see how many are already
doing this), we also use the CA glue trick, thread it through "two" heels,
pull flush to the first, then you can apply finger pressure on both heels
(both sides of the cut) to keep the cloth taut for a nice neat cut.
(watch where you're cutting though!!)

This pattern works nicely for knuckles too, and if I may; there are many
shades of white/ivory yarn, making it possible to do "invisible" knuckle
bolstering, should your shanks have sat on the supplier's shelf a bit too
long. ;>)

Hi Mark,
	Finally got the time to look at the photos: nice display of a worthwhile
procedure. One comment: I would sure iron that felt prior to reinstalling
the stack on the keys. I'm talking fairly moderate heat, moderate pressure,
regular clothes iron, one minute or so for the whole stack. Aids in
minimizing later capstan turning, and reduces friction. Speaking of which,
I'd brush on some powdered teflon while I was at it, too.
