doping pinblock/piano upside down

[John M. Formsma]

Bill B,

Thanks for the help. I think the pins have been doped before, so CA may be
the best bet.

The only problem about doing this from the top is that the pins are driven
in very close to the plate, making it impossible to avoid getting CA on the
coils. What would CA on the coils do? I think I want to avoid it.

Best regards,

 Carl Meyer posted his success with epoxy. Is that preferable to CA, or will
 both get the job done well? >>

Yes, this is a good idea but I would suggest doing it from both the bottom
and top.  Epoxy will work well too, it just has to be thinned enough with
acetone so that it is watery and will soak into the deteriorated wood.  It
should cost less than the same quantity of CA and the fumes will be far less
harsh.  If the pinblock has been previously "doped" with another kind of
solution, use CA.  It will blend with just about anything while the Epoxy
will work best on mealy, dry and fragmenting wood.  Using two applications
is
also your best bet.

Good luck,
