Oversized screws are available from Yamaha - or at least, they used to have
them. I haven't checked recently :-)</FONT></SPAN></DIV>

Swedging the hole works very well in many cases. I use a fine
screwdriver with a sharp tip, position it at the edge of the hole and tap with a
small hammer until you have a mark in the aluminum. Repeat in a star
pattern around the hole on all sides, so that you end up with 8 little lines
radiating out from the hole. The original screw should tighten normally
now.</FONT></SPAN></DIV>

groove in the aftermarket parts I'm using doesn't quite line up with
the wire Yamaha recesses into their action rails. This pulls the flange

nice alignment.</FONT></SPAN></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">You drill out the hole and tap
it, then insert the little coil which disappears into the tapped threads,
and then you’re good to go! Maybe this has been shown on CAUT before, I
don’t remember seeing it. The new screw is actually a machine screw with
fine threads so it takes a few more rotations, but this is way better than
anything else I’ve ever tried. The package shows a bolt, but what actually
goes in has a Phillips head and looks like a normal
screw.<o:p></o:p></SPAN></FONT></P>
