More importantly, imho, is tightening down on the pinblock screws=
 to make sure the block is snug up to the plate.  I had a Yamaha=
 with tuning problems and Yamaha said to take the tension down=
 and tighten those screws.  It worked.

You are going to have to fill that gap.  A less messy way to do=
 it than using a liquid filler is to first lower the tension=
 slightly (maybe a quarter of a turn on each tuning pin) and then=
 tap maple wedges every two or three inches along that plate=
 flange gap.  Restoring the tension will tighten up those=
 wedges.

I ran into a new one the other day. A local dealer has pianos=
 made for 
them by Dong Bei in China. I was asked to make a service call on=
 a 
small grand that was sold to a church. This was my first=
 encounter 
with one of these pianos. The local tuner was having trouble with=
 
tuning stability and they asked me to have a go at it.

Overall, it looked fairly well built and pin torque was very 
consistent. String rendering had a mushy feel to it but I was=
 able to 
set pins. It seemed stable while I tuned and sounded like a=
 million 
bucks when I was finished. The other tuner had told the dealer=
 that 
the piano was going out of tune even while he was working on it=
 so I 
was very meticulous with my tuning and was looking everywhere for=
 an 
answer.

Then I found something that blew me away. I checked the pin block=
 fit 
and found that the bl! ock does not even touch the flange, at any=
 point. 
Not only could I put a business card in the gap, bass to treble,=
 but 
there was a huge gap. I could have put the thickness of three or=
 four 
cards in it with no problem.

The previous tuner had just tuned the piano eight days before and=
 when 
I got there the treble was a good 25 cents sharp. I do not know=
 this 
tuner so I can't speculate about his experience. I asked a ton of=
 
questions about humidity and temperature fluctuations and I=
 gather that 
it has been pretty stable. They do not turn off the heat during=
 the 
week, etc. I am going back this week to check my tuning. I can't=
 
imagine it's going to be stable with no attempt whatsoever at pin=
 block 
fitting.

Have any of you seen anything like this? I know there is a lot of=
 
griping about the pianos coming out of China but the rest of the=
 piano 
really looked fairly well made. The piano is named Steinhauer and=
 is 
made exclusivel! y for this dealer. I would be very interested in=
 
hearing any experiences you may have had like this. If I go back=
 there 
and my tuning is FUBAR I am going to have to condemn this bird. I=
 have 
a good relationship with this dealer but I smell trouble.

Mitch, have you dealt with any of these yet?
