    In updating an 1879 3/4-plate 48" Stwy vertical, I have to convert the wippen-damperlever contact from wooden "spoon" (fixed flange) & setscrew in the damper lever, to the modern metal spoon. I have 50  such spoons, leftover from when supply houses had them, and need another ~25. Unfortunately, no one (Pianotek, Schaff, Forte Piano Supply, Renner, Stwy) carries them. I thought I might make do with the spoon for the grand rep's jack-adjust button. Unfortunately, the latter is flat, as opposed to an actual "spoon" curve, and unlike the jack-adjust spoon, the vertical damper spoon is moving (as with its damper lever).



    Any idea about a back-channel to a piano factory, as a source? I'm going to do the conversion with the 50 I have (from the bass on up, where most of the wire spending is done). Maybe, I can assume that the "flat" spoons won't dig as much into the damper lever felt if I put a slight bend in the spoon so that its top edge is no longer the first to hit the felt.

    But I'd love to find some real upright damper spoons.

    Bend the flat section of the jack rest. Salvage damper spoons from a junk upright action.

    Dang, I just demolished two of them this Fall: an ornate I&P, and a no-name ("Milton", who knows …) 48"-er from the '30. But both of those had damper flanges offset from the butt flanges: straight spoons to be bent to make the offset. I need one from a double-flange action, a Stwy or a Baltimore Knabe.

    Some factory, somewhere, is still making them. Or some tuner, somewhere, is ready to get rid of theirs. It's been decades since installing jack adjusting spoons on 19th- century Stwy reps was a regular piece of work.

    I have a Cable console action that is going out. I'd be glad to measure the spoons to see if they might work.

    Thanks for the offer, John. They are 1-3/8" tall, with a 9/32" fluted stem, and are an exact match for the grand rep jack-adjust spoon except for the actual "spoon", not flat but curved. I've got plenty of straight-stem spoons which block the wippen flange screw. The "double-dogleg" is required when there is no offset between the damper flange mounting and that of the butts/wippens.

    Schaff used to offer their connections to the piano industry for odd parts not called-for enough to get in their catalog. But that was back when this country had a piano industry. Probably these would have to come special order for EU, something that Jurgen or Melanie Brooks could swing.

    Tokiwa still makes action parts for that era Steinway uprights.

    Or maybe drill a small round bottom hole in something hard and peen the flat jack spoon into it ( use a round-ended drift?)
