    I was working on an early 80s Baldwin R.  First time customer for me.  The action regulation was a mess because the previous technician replaced the hammers with new flanges and shanks AND didn't regulate the action afterwards.  No big deal.  I spend some time regulating the action so that it played well.

    But in my observation, the dampers were bouncing horribly against the backs of the keys indicating the damper upstop rail had come loose (there was 1/2 inch extra motion after strike).  
    But... Somebody nailed the rail against the belly.  I've attached some pictures.  My first guess was the mounting screws were stripped in the belly, but they aren't.  They snugged up nicely.  My second guess was.... well, I don't have a second guess.  I have NO idea why someone would have nailed this rail to the belly when the screws functioned.  Let alone nailed it at a regulation that was FAR too high.

    In the end, I pulled them out, tightened the screwed at the proper regulation, and it worked great.

    Any guesses?

    Dave,

    For what it's worth, I have seen several Baldwins with brads in the damper unstop rail, presumably done in the factory (as backup, in case the screws come loose?). This approach does not seem to have caught on with other manufacturers.

    Mr. Foster

    I have seen so many Baldwin grands from the 60's and 70's with the same nails that I have always assumed it was a factory policy.  I've never understood the why of it but am pretty sure that the how of it was that someone depressed the damper pedal as far as it would go while the screws on the stop rail were loose and then nailed the rail in place. Then they went back and tightened the screws. At least with this method they could be pretty sure that the rail wouldn't be moved by excessive use of the "rhythm" pedal.

    I've seen  this on just about all Baldwin grands I've worked on. You did the right thing

    Dave - 
    You said:

    Well, that's all fine and good, but now you should put the brads back in, or maybe 1/2" #3 phillips screws.  1/2 kidding.

    Okay, it was a long time ago, and I was working on the sostenuto regulation of an early Baldwin SD-10. It had aluminum parts, and the screws had dug into the aluminum, so when I tried to tighten the screws in a different place, the parts would wedge back into the old divots. I ended up taking them all out, filing them flat, and putting a washer under each screw.

    However, since I was being thorough I had gotten hold of an old Baldwin tech manual. Being new to this and feeling insecure, I was corresponding with Horace Greeley about it. I read in the manual that i should set the sostenuto rail to the right height, and then use brads through the small holes kindly provided to secure it in place. I quizzically quoted this to Horace, and he said "grrrrrrrr". 

    So it doesn't totally surprise me that Baldwin damper up stop rails have been tortured by the same approach.

    Of course, if said Baldwin grand has not been subjected to "gospel damage", it shouldn't be that hard to keep the upstop rails set at the right height. It might be good to check for a stop block above the right pedal if you suspect the piano is going to get a lot of heavy playing. If there isn't one, a cube of scrap hammer felt works well.

    My guess - damper up stop rail being used as a pedal stop. Nailed in place to keep it from traveling up, up , and away.
