I did a swing test on random hammer flanges of a Yamaha C6 and was getting 3 to 4 swings. Somewhere in my mind I remember LaRoy stating Yamaha flanges should swing loose at 6-7 . I used a spring gram gauge and was getting 2-3 grams. Maybe I am using the gauge incorrectly but I found an article in the PTG Journal showing the same gauge and I am placing it in the same place. Susan Graham wrote the article but it did not have specific readings/measurements to look for.
The bass hammers I tested all where in the 6-7 swing range but the low tenor mid range and high treble samples where all 3-4. Should I just lubricate these flanges for now to get more swing ???
