<DIV>Hi Ken,</DIV>
<DIV> </DIV>
<DIV>Thanks for your input. Yamaha provided "appropriate" cord sp=
iraled around a cardboard tube of such a diameter that when you slice t=
he cord in line with the tube, you wind up with #90 little 44mm pieces of sl=
ings-to-be (10mm to be glued to each side of the flange and another 24mm for=
the sling proper). Think I wi<SPAN class=correction id="">ll</SPA=
N> follow your (and Dale <SPAN class=correction id="">Erwin's</SPAN>) ad=
vice, get new flanges and re-schedule.</DIV>
<DIV> </DIV>
<DIV>Thanks again,</DIV>
<DIV> </DIV>

his situation: What's the cost of a<SPAN class=correction id="">ll=
</SPAN> new flanges, versus your labor charges in replacing the slings? &nbs=
p;Getting the sling the right size is very important to maintaining consiste=
nt spring tension. The only technique I have seen for this th<SPAN cla=
ss=correction id="">at</SPAN> looks <SPAN class=correction id="">li<=
/SPAN>ke it would really work involves getting the flanges off the butts. &n=
bsp;This would only be practical if you replace the flange, and then replace=
the slings in the shop, thus creating more replacement flanges. I hav=
e a small box full of this type of flange waiting for me to get around to re=
placing the slings. Problem is, I can't replace the slings for less co=
st than I can buy new flanges.<BR><BR>If you're locked into doing this on Mo=
nday, your plan is correct. You'<SPAN class=correction id="">ll</S=
PAN> have to remove the hammers. Removing the dampers <SPAN class=co=
rrection id="">wouldn</SPAN>'t help, since from the damper's point of view=
, the sling is glued to the "back" side of the butt flange, i.e. the side op=
posite the rai<SPAN class=correction id="">l.</SPAN> You can't get=
to it from that side of the action. I'd use CA glue, although I don't=
use CA for anything because I'm allergic to the fumes. Anything else =
would take way too long. Unless Yamaha provided pre-cut cords, I don't=
know how you could get them all the same/right length.<BR><BR>Good Luck,<BR=
