Need help with some questions regarding Kawai KG-2C

[symsarah]

Dear all,

I'm currently looking at a Kawai KG-2C which was made in late 1978. The strings are rusting and the felts on the hammers have grooves. Attached are the photos. It plays well, but some of the keys make clicking noises. I was wondering if a major service to polish the strings to remove rust and sanding the felts would be enough or would it need an entire re-string and change of hammers? And would the clicking noise in the hammers be attributed to some loose connections that can be solved by tightening? Thank you so much for your help!

The 5’10” Kawai is probably their most popular model.

This one is 35 years old and replacement string is due. The hammer set looks to have had light use and can be shaped and voiced up to original spec.

So restringing, hammer shape and voice, and full regulation.

 Not sure where you are located but here in Vancouver, Canada that cost of that work would out value this instrument by more than double.

I've seen and delt with much worse rust than that. Unless you can't stand the sight of it I'd just leave it alone. Or in the case of bass strings, if they sound dead you need to do one of a couple of different choices. The only way to truely get rid of the rust is to restring incidentally.

The hammers are not beat just judging by the photos and not seeing them in real life. Bad hammers that need replacing would look much worse and the strike surface would be flat and have already been voiced so that voicing again couldn't correct them. These look decent actually, again judging by your supplied photos only.. Judging from the photo only , again I'd leave them alone. If the voicing is off have it voiced, assuming the strings are sounding good.

 Clicking can be anything from worn pins or bushings to just a loose part that needs tightening, like a hammer shank to mount surface for instance. Or even a loose hammer on it's shank that needs gluing. A tech would have to take a look, a good idea anyway if you are thinking of purchasing this piano.

I don't claim to be a professional tech bye the way, I've just done a reasonable quantity of work on pianos !!
