I tried to remove the action, but the drop = screws are hitting the pin block. I was afraid if I pulled to hard to = get it free, it would peel back the polyester of the stretcher.=20 Except for the low bass, there was actually lost motion between the = keys and the wippens. That is why I tried to remove the action. If I = recall, there was some talk earlier about Young Chang action brackets = "growing." I looked at them, but could not see anything unusually. They = are light blue.=20 I didn't have my tuning kit with me, so I couldn't lower the glide = bolts to see if that would help. But I don't think that is the problem. = Structurally I couldn't see anything wrong.=20 Anyone with a solution.=20 Wim=20 Wim, I just did one recently with the same extent of expansion you are = experiencing. It is 100%, absolutely, the case of expanding action = brackets growing upwards, extending the height the action frame to the = stretcher area. Which explains the gross lost motion. You are on the right path with the idea of lowering the glide bolts. = In fact if that doesn't create enough clearance to get the action out = Young Change suggest you take a hack saw and cut the action brackets = apart, which is what I ended up doing. Actually I used a Dremel tool = with a cut-off carbide disc and it did the job quickly. Also note that even though this is a Young Change piano , the warranty = work still has to go through Weber. One last item when ordering the new brackets take note that there are = 2 different sizes ( height wise). You basically take a crap shoot and = hope you get the right ones. Otherwise, more down time for the customer. The manufacturer will sometimes cover the complete regulation job, at = least they did with us on several that we corrected.
