[pianotech] treating bridges with CA

[Barbara Richmond]

Thanks, Ric. 

That's something more to think about and I'm not crazy about CA. But, dang, the thought of having to space strings, the hammer mating, etc., takes the repair out of the fast and dirty category. :-)

Hi Barbara 

Just thought I'd throw my two bits in here. Personally I never even 
think about trying to apply CA or Epoxy to the bridge without removing 
the strings. It just ends up being less effective then I want (and know 
it can be) and too much of a hassle to avoid getting either onto the 
strings. 

I DO quite often use Cellulose lacquer in cases where an improvement is 
needed but the customer wont pay for the extra time it takes to remove 
strings (as I go with CA, complete sections with epoxy). I thin it down 
to about 8:1 from the can, use a needle bottle and soak it in as much as 
the bridge will take. Its also very easy to cover the bridge notch with 
if you need... and has a nice tendency to wick in under the string 
filling bridge indentations without getting on the string much at all.. 
It does get of course on the underside of the strings back of the bridge 
pin... but this is not a problem. Any lacquer that DOES get on the 
strings forward of the bridge pins is very easily removed either while 
still wet or while dry. 

Frankly... I'm doing more and more of this as I find it solves very much 
of the exact same problems CA is used for here... is much much easier to 
deal with in general and I dont have to worry nearly so much about the 
fumes..... tho to be sure Cellulose and thinner is not exactly the most 
healthy thing to breath in deeply either. 

Try it... you may be surprised. I carry a bottle with me all the time 
now... helps clean up falseness of a variety of types. Really handy for 
that wavering undefined wangishness found often in the 1' area (octave 5) 

Cheers
