YC Growing Brackets

[Farrell]

Well, yes, loosening or removing the keybed did occur to me - I saw that it had many screws holding it in - I didn't know if that was all that was holding it in - some are morticed, etc. - just don't know about a YC - but then also you would have to remove the legs, and then you have the weight of the piano - I just figured that was a very last resort. How would you use a pinblock support jack to increase the distance between the pinblock and keybed if the action is stuck in the action cavity? Just didn't seem to me to be a good option - only a last resort.
