Hi Roger. Thanks for your input. I will file it in the regular grand file. I
did the square on Saturday. The damper wire guides are about 2-inches long
(thick?). I tried several thicknesses of wire and finally ended up using a
kinda thick rubber mute wire - up and down repeatedly pretty fast - it built
up quite a bit of heat. Then squirted some protek down there and it seemed
to work quite well.
