Earlier, we\u00a0removed the main action rail (hammers and shanks) and the wippens rail. The upstop rail also was\u00a0removed.

A product called <a href=\"http:\/\/amzn.to\/2lK0ZmY\" target=\"_blank\" rel=\"noopener noreferrer\">Flitz Polish<\/a> is recommended, because the pins are nickel-plated brass or steel, and abrasives will remove the plating. Celeste, a piano shop technician and action mentor, provided a shop-made tool made from a block of felt that chucked into a drill, and worked wonderfully. A dab of Flitz on the pin tip, a quick spin with the felt polisher, and a wipe with a soft cloth to finish.<\/p>\n<div id=\"attachment_587\" style=\"width: 160px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2017\/03\/Straightening-the-front-rail-key-pins.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-587\" data-attachment-id=\"587\" data-permalink=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/2017\/03\/05\/weber-piano-project-keyframe-cleanup\/straightening-the-front-rail-key-pins\/\" data-orig-file=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2017\/03\/Straightening-the-front-rail-key-pins.jpg\" data-orig-size=\"1280,959\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;2.2&quot;,&quot;credit&quot;:&quot;Jim Kerkhoff&quot;,&quot;camera&quot;:&quot;iPhone 6&quot;,&quot;caption&quot;:&quot;Straightening the front rail key pins&quot;,&quot;created_timestamp&quot;:&quot;1488194380&quot;,&quot;copyright&quot;:&quot;Jim Kerkhoff \\u00a9 2017 http:\\\/\\\/creativecommons.org\\\/licenses\\\/by-nc-sa\\\/4.0\\\/&quot;,&quot;focal_length&quot;:&quot;4.15&quot;,&quot;iso&quot;:&quot;250&quot;,&quot;shutter_speed&quot;:&quot;0.041666666666667&quot;,&quot;title&quot;:&quot;Straightening the front rail key pins&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"Straightening the front rail key pins\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Straightening the front rail key pins&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2017\/03\/Straightening-the-front-rail-key-pins-300x225.jpg\" data-large-file=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2017\/03\/Straightening-the-front-rail-key-pins-1024x767.jpg\" class=\"size-thumbnail wp-image-587\" src=\"https:\/\/jimkerkhoff.com\/test-roycreekranch\/wp-content\/uploads\/2017\/03\/Straightening-the-front-rail-key-pins-150x150.jpg\" alt=\"photo showing Straightening the front rail key pins\" width=\"150\" height=\"150\" \/><\/a><p id=\"caption-attachment-587\" class=\"wp-caption-text\">Straightening the front rail key pins<\/p><\/div>\n<p>The front rail key pins are oval-shaped in cross-section. By turning them slightly, a small amount of \u00a0side-to-side key play can be taken up as the key bushings wear. Since the keys got new bushings, it is important to center them back up. Celeste got me the clever tool used for this purpose. She also recommended covering the now polished and centered pins with <a href=\"http:\/\/amzn.to\/2m9Sa9f\" target=\"_blank\" rel=\"noopener noreferrer\">ScotchBlue Painter&#8217;s\u00a0Tape<\/a> for protection while sanding the dirt off the keyframe.<\/p>\n<p>Next, it was time to remove the back rail cloth. In this case, there were two layers, as if a second layer had been added later. They both peeled off easily, leaving a residue of red felt and animal glue.\u00a0An application of Windex, followed a few minutes later with a sharp chisel easily removed the residue. One has to be careful though &#8212; you don&#8217;t want to gouge the wood underneath the cloth. Finally, the entire keyframe got a light sanding with 220 grit sandpaper to remove the years of glue, grime and funk.<\/p>\n<div class=\"tiled-gallery type-rectangular tiled-gallery-unresized\" data-original-width=\"1300\" data-carousel-extra='{&quot;blog_id&quot;:1,&quot;permalink&quot;:&quot;https:\\\/\\\/jimkerkhoff.com\\\/test-roycreekranch\\\/2017\\\/03\\\/05\\\/weber-piano-project-keyframe-cleanup\\\/&quot;,&quot;likes_blog_id&quot;:62631746}' itemscope itemtype=\"http:\/\/schema.org\/ImageGallery\" > <div class=\"gallery-row\" style=\"width: 1300px;

This old keyframe has laminated wood instead, and the laminations have small gaps at the top. I&#8217;ll repair\u00a0them with gap-filling cyanoacrylate glue a little later. For now, a coat of shellac will finish the process and <em>voil\u00e0<\/em>, we have a reconditioned keyframe! As a last step, I applied a coat of McLube to the key bushings. This is applied with a pipe cleaner and will reduce the pin friction even further.<\/p>\n<p>Finally, we tested my bushing work on the keyframe. A little disappointing. I had applied bushing material too deeply into the mortises and it was binding. Too much friction. Celeste thought the problem could be remedied by cutting the excess material out with a scalpel, so I guess I will be spending a little more time on the key bushings. After all, it was my first attempt!
