<DIV>I personally like 8-10 swings. I feel you get a better touch. Darrel Fandrich convinced me of the value of this.  The important thing is that the flanges are firm.  The best way to check this is to use a straight edge or long shank screw driver and support the shanks and slide it back and forth. You will immediatly see the ones that are too loose because they wiggle. </DIV> Less friction means more power, lighter touch, faster repetition. <DIV> Bob Hull <hullfam5@yahoo.com> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">List, I was preparing a new set of shanks and flanges for an action rebuild (a recital hall piano)and found that the pinning maybe too loose. Many of them will swing 8-10 times before coming to a stop; some will swing 11 - 12 and a few 7 times. These are high quality parts from a reputable manufacturer. The humidity in my shop is in the mid 50's. When winter comes and the humidity in the recital hall drops way down won't these be to loose? I was looking for about 3-5 swings in the bass graduating up to about 7 max. in the treble. I am facing a deadline and may need to get another set sent if the manufacturer agrees which will cost me at least 2 days. Would you repin, reorder or what?
