The instruments are not heavily used and conditions in t= he rooms are stable. Central heating with humidifiers. Is this a seasonal thing or is there a common adjustment I should try. Regards Steve </BLOCKQUOTE> Steve, In recent times I've dealt with many sticky keys caused by tight balance= rail holes.  Easing the keys will often help.  Any increase in ex= tra weight required to push a key back into position will cause the action t= o not function at optimal level, and possibly not at all.  Before you t= ake corrective measures, figure out where the problem is. Work back from the key.  Keyslip, front rail bushing, balance rail = bushing, between the keys, any of the centers in the flanges of the whippen = or hammer.    I don't know if this is your job or not, but if it isn't, it may fall un= der the "don't try this at home" category.  If you're a tech, or becomi= ng one, look at it as an opportunity to hone your skills!
