Pinning on new flanges

[Richard Brekne]

With respect Keith..

This is not really such a difficult question to get a <<correct>> answer 
too.  On the one hand pins need to be tight (firm) enough in the 
bushings to provide as solid a hammer travel as is possible. Essentially 
that means the firmer the better. Directly opposed to this is that the 
pins need to be loose enough to provide for adequate movement to 
facilitate .... play :)  The best possible solution is, obviously 
enough  as tight as they can be while not causeing the flange as to be 
to tight to move freely enough.  In practice... this works out (in the 
case of the hammer flange on the grand) to be the equivalant of 4 - 7 
swings.  Some people feel 4 is too risky, and I agree personally.  But 
beyond 7 is pure and simply pointless loss of stability with nothing to 
gain  IMHO.

Ok... so there is a window...  but not much of one, and personally I 
think that qualifies real well as being a right way of doing things.  
And as far as I can see.... the consensus on the matter is clearly... as 
in overwhelmingly in agreement. I think the list got it right.

But then,,,, thats just my view.

Cheers :)
