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. Terry Farrell Piano Tuning & Service Tampa, Florida mfarrel2@tampabay.rr.com
