I saved the instructions (on a disk) for replacing those pesky=20 little spring cords and now I can't find it. Would someone please send the= m=20 along to me (You know, the instructions that include removing the hammer=20 rail.). Though I read them--a long time ago--I can't remember all the deta= ils=20 (Guess I've been eating too many aluminum bushing cauls), like how long the= job=20 is supposed to take. =20 Thanks, =20 Barbara Richmond, RPT =20 Barbara, =20 Here are instructions. I got them from Tom Cole, RPT. He can do it in=20 around 2 hours, give or take. I'm sure his shop area is far more efficientl= y=20 organized than what I was using at the time. The first time took me around= 4,=20 second time was about 3 hours. I see another one on the horizon soon! =20 Dave Stahl =20 =20 Problem: Hammer return spring cords are breaking due to unknown cause Symptoms: Cords have become a brownish color Random breakage is occuring Touchweight is affected on some notes; hammer sometimes falls into strings=20 on slow release Solutions: Replace hammer flanges Replace cords Condition of action: If condition of the hammers, pinning, and travelling/mating to strings all=20 good, replace cords.

Loosen hammer butt plate screws 4. Remove hammer assemblies from flanges and let hang from bridle wires 5. Straighten any bent return springs 6. Tighten all hammer/damper/wippen flange screws 7. Tilt action 90=B0 so that the hammer flange cord slots face up 8. Using specially adapted shimming chisel, clean slots and vacuum up debri= s 9. Wrap 90+ turns on dowel with new cord and cut turns with razor 10. Glue one end of each piece to one slot on each flange 11. Return to the first flange and trim each cord to length 12. Glue other end to remaining slot; check with gauge 13. Replace hammers; tighten butt plate screws; hook springs under flange=20 cords as you go 14.
