[CAUT] capstans

[Don Mannino]

Dave,
 
An old fashioned way that I was taught to do a good repair on loose
capstans is to use bridal tapes.  Remove the capstan, spread glue on the
bridal tape and put it in the hole, thread the capstan into the hole,
and cut the tape flush with the key using a razor knife.
 
I have also used thin C/A glue, which is much faster and doesn't even
require disassembly.  After the glue sets the next time you turn the
capstans there will be a loud SNAP, then they should work nicely.

	Does anyone have a favorite (easy) way to fix loose capstans?
We have a 6-year-old grand where the capstans are so loose that you
can't keep a good hammer line.  Within a week of regulating it several
hammers are back down on the rebound felts.  None of the capstans are
hard to turn and many are way too loose.  Unfortunately this is from the
5-year-warranty company so I'm on my own with this one.
