[CAUT] Gram Tension Guages

[David Love]

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.

David,

The Correx gauge has a needle that stops when the motion stops, but the
$190.00 price is hard to cough up. 

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!

I prefer swings since I have a hard time telling exactly when the gram
gauge
starts to move.  Seven to eight swings is what I like and the flange
should
not fall of its own weight until the screw is inserted.
