David, My brush is flat, sort of chisel edge, 1/2 inch wide. It's the blue-handled tool in the following photos. (You may have to zoom in a bit to see the brush.) https://picasaweb.google.com/lh/photo/BUvNz7DjB4tDrh9-Zs7RtTzOW-y0ertuNSKR2rD1CjY?feat=directlink https://picasaweb.google.com/lh/photo/elCjBSL1HQBnrG7xz7_JRTzOW-y0ertuNSKR2rD1CjY?feat=directlink It came in a package of extremely cheap brushes I bought in a craft store. Nothing fancy. I follow the same method as John, except I find I can do only 5 keys at a time, depending on the humidity. By the time I'm done spreading glue onto the 5th key, the first one is ready to accept the keytop material. The PVC-E goes on white and as it dries, it goes translucent and gets tacky. I put the keytop on when the glue is starting to go translucent and starts to get tacky, but still has some streaks/brushstrokes of white. I also do not clamp. I press the keyfront into my work surface first to make good contact, then I lay the key down on my work surface and massage the keytop into the glue from head to tail. I'm aligning, pressing, and wiping away glue squeezeout all at once. Set the key aside and you'll find the the next key is ready. It goes quite fast and you get a rhythm going. I also look back and check my work to make sure none of the keytops drift. Work time is quite long. If something does drift, you'll find that you can fix it with a really firm shove. Hope I've helped, Chris S. -------------- next part -------------- An HTML attachment was scrubbed... URL: <https://www.moypiano.com/ptg/pianotech.php/attachments/20120719/b6f3812e/attachment.htm>
