Ideas have changed somewhat I guess. I think 5-7 grams of friction is too much. I usually aim for about 2 which is 7-9 swings bass to treble respectively. On a piano that gets heavy use in, say, a university setting, I wouldn't mind if they started out higher. For a Stanwood style weigh off, 5-7 grams of friction in the flange creates too many problems getting an accurate weigh off, especially upweight. In general, I find that for a total of 12-15 grams of friction in the bass maximum, 2 grams in the flange is about all I want.

I'm leaning towards using swings again, but isn't 7-8 a bit loose? I used to go for 3-5 (that was generally around 5-7 grams) in our practice rooms and that seemed to last a couple years. I also thought that the flange should be able to support the weight of its screw. Boy, it seems this is an area with a lot of varying thoughts!

Seven to eight swings is what I like and the flange should not fall of its own weight until the screw is inserted. David Love davidlovepianos at comcast.net
