[pianotech] CA glue vs. PinTite or Garfield's?

[John Ross]

A small drill to drill the bushing can be made from piano wire cut at a 
slant.
That way it can be long enough and won't break, as it is not a brittle as a 
drill bit.
I often use the ends of new bass strings as an inexpensive small drill bit. 
Mind you, not for precision work.

The most recent bottle of thin CA I purchased was from Mercury Adhesives,
product number M5T .http://www.mercuryadhesives.com/products.htm#M5T.  I
discovered that the bottle is indeed no-clog, and better yet, that the tip
is designed to accept standard blunt needles with polypropylene hubs.  I've
purchased a pack of 100 22 gauge by 1" blunts (about .75 mm outside
diameter) that allow me to apply the thin CA _very_ precisely.

I now am able to spot-treat untunable pins in old uprights as I tune, with
no tilting.  With this size of needle, I can reach past the plate if there
is no bushing, and sometimes reach in beyond the surface of the pinblock if
there's a bit of a gap.  A careful application at the very top of the pin,
right at the block, will wick in, and a Q-tip is all that is needed to catch
the excess that occasionally trickles out.  Only once have I treated an
entire pinblock.  The piano I treated this week needed application on about
half a dozen pins.  In the case of plate bushings with no gap, I would not
be adverse to drilling through the bushing with my smallest drill bit to
gain access to the pinblock.
