I might add that you will have to be careful in doing this. If there is not enough after touch when you lower the rail, you will have bobbling hammers. You may want to check one or two in each section, bass, tenor, treble to see what kind of feel you have in this before proceeding all the way with the others. Also, if they keys are not level, that will make a difference in your aftertouch as well. It will be inconsistent. While lost motion eliminates a lot of problems, the rail will still have to be set at the proper height first. Usually, when the blue screws are set, that is about where the action belongs, but nothing is set in stone with pianos. I do the same as Tom, removing keys, turning the capstans, getting a feel for how many turns are required before putting it back in and then do a whole bunch at a time once I get the feel for it.

In the past I have manipulated a capstan wrench to get in there but it is still difficult . I now remove each key and turn the capstan up and replace. After a few you will get a feel for how much to turn and it goes quickly . The other tip is that before you touch the capstans the rail you describe can be adjusted to take up lost motion wholesale. The silver machine screws at each bracket can be loosened (they are probably loose already) and you will also see-feel small blued round head screws that pass through each support bracket and screw into the rail . Remove those . Between the wood rail and the action bracket are sandwiched small wood spacers that can fall out if you are not careful. There are one or two at each bracket and they are often different thickneses . With the rail loose, push down to eliminate lost motion and tighten each machine screw making sure those spacers stay put.. I crank those machine screws pretty tight as they thread into the metal bracket and will not strip out. I chose to leave the small blued wood screws out. This will get you close --THEN adjust capstans as described. Hope this helps, Tom Driscoll Subject: [pianotech] Wurlitzer spinet ugh Hi Everyone, I worked on a Wurlitzer spinet today and had a question about it. It's a serial # 506984. I'm not sure how to adjust the lost motion on it. The keys are not connected to the stickers, but there is this sticker rail wit screws on it that faced me as I sat at the piano. The adjustment for the lost motion is on the keys themselves. So my question is when I head back in six months to tune it, will I need to remove that rail in order to access the capstens? There isn't enough room to get your finger at the end of the key with that sticker rail in the way because the key sort of slopes down.
