I've seen this happen a few times when the height of the new flanges is smaller than the originals or the washers are thinner. The screw is bottoming in the rail. You can either redrill deeper or add another layer of sandpaper or another washer. The washer moght be the fastest easiest solution since adding more sandpaper over the rail will affect the action spread.

Denis, 

I'll certainly be interested in hearing the solution to this problem. I service some little no-name, rebuilt piano that it is hard just to hold the flange in place and tighten the screw--and have the flange where you want it. "What the....?" was my reaction to tightening the screws. I've never run into this before. It felt like the screws were either tight or loose--in an instant--hardly any screw turning involved. 

These were nice parts--they looked like a pre-hung set. I wondered about the height of the flange and the length of the screw. It seems to me I looked at the length of the screw through the flange, but now I can't remember what I saw. (Isn't that helpful?) Should have taken some pictures. 

This piano also has sandpaper on the hammer flange rail.

List, 

At the Flint School Of Performing Arts, I have a Baldwin SD that the hammer spacing will not stay put. About 7 years ago I put hammers shanks and flanges in it. I used Renner USA shanks and flanges. The problem is, no matter how hard you tighten the flange screw, the hammers eventually move left or right after a few hours of heavy playing. 

Some of my Ideas are: 

1. replace the sandpaper on the rest rail with a heavier grit, which might necessitate a slight let off and drop adjustment. 
2. the flanges have that little "notch" in the back, so I thought installing bridge pins through the notch right into the rest rail. 
I used to have a 9' Bechstein that I took care of that had the same. 
3. remove a small amount of wood under the flange, so that tightening the screw would transfer some of the grip out to each end of the flange. My least favorite option. 

Any of you ever had this problem? Any help is appreciated.
