opinions on this CA job for loose tuning pins

[John M. Formsma]

List,

I've done several "CA jobs" to fix loose tuning pins. All have been on 
older pianos where the pins were quite loose everywhere, and all but one 
was successful.

This piano is a 1994 Baldwin Acrosonic. There are probably 30 or more 
somewhat loose pins, with up to 10 needing definite attention, although 
they are now tunable with a CyberHammer impact lever. But over the 
years, they have definitely gotten looser, so it's now time to repair 
the problem.

Does CA work well for this kind of thing? I'm thinking a fairly light 
application so as not to return the pins to their former "Baldwin why 
the heck do you make 'em so dang tight" state. What I'm also wondering 
is will the CA get past these new pin bushings down into the hole? Or is 
it just going to glob all over the bushing?

Ordinarily, I could just remove pins and swab the inside of the hole 
with thick CA, but with there being so many and having to un-bend the 
wire coming out the pin hole, it would be so much easier to tilt and do 
some preventative maintenance...if it will work.

Of course, I want to be the most fair to the customer, and think that 
the CA route is probably the best to try, considering that this seems to 
be an endemic problem, and will eventually require treating all the 
pins. However, having no experience on a piano this new, wanted to ask 
if anyone has had similar experience.

Your thoughts?

Thanks,
John Formsma
