Grand Hammer Flange Center Friction

[Roger Jolly]

Hi Terry,

Wow that's high. 4 gms. That's about 4 swings.  The test I use is the one
that many Yamaha tech's use.   The shank and flange should hold horizontal
under it own weight,  the flange should then drop smartly ( not creep,
that's too tight) with the addition of the flange screw. Once you get to
really know your broaches, you just know the feel of the desired friction.
Another tip listen carefully when repinning, (before and after), you can
train yourself to hear a lack of friction.

Regards Roger

>Roger Jolly - are you using 5 - 7 grams friction in the hammer flange
centers as a general target? I know you like your centers a bit tighter
than some recommend. How many swings does that come out to? Thanks.
