I had to replace hammer spring cords on a Yamaha U1 and it did not have the butt plates holding the hammers to center pin, so I was unable to use Jon Page's protocol. Instead, after fighting with a few, I made this simple fixture and share for your amusement and so Joe the Tool Captain can tell me how I did it wrong. (just kidding, Joe) IMG_20130104_141102 I figured out my little flush trimming saw was perfect for cleaning out the grooves. IMG_20130104_133142 The jig is simply a nail near the edge of the work bench that I drop the flange over. Using a trap work spring screwed to the bench next to it, I can lift the spring and put its hole over the nail as well, trapping the flange to the bench. IMG_20130104_133155 I trap the first end of the new cord under the trap spring as well I dab a tiny bit of thick CA into the grooves using my bulb syringe and then line the cord into the left groove. There is a nail in the front of the work bench as well that I wrap the cord around. Using tweezers I then pull it up into the other groove, hold it firmly then spray some accelerator, wait a few seconds, trim the excess and remove from the jig. My workbench top is just cheap OSB so I have no qualms about drilling holes in it as needed. It's ugly, but it works.
