However there are also many unusual problems which cannot be found in any textbook and require a special degree of detective work to fix.<\/p>\n\n\n\n<p>A client in 2024 contacted me because several keys in the top octave were staying depressed. When I arrive and inspected the piano I could see the problem which he described, but determining the cause was another matter. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/1-keys-dipping.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"612\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/1-keys-dipping-1024x612.png\" alt=\"\" class=\"wp-image-380\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/1-keys-dipping-1024x612.png 1024w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/1-keys-dipping-300x179.png 300w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/1-keys-dipping-768x459.png 768w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/1-keys-dipping-1536x918.png 1536w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/1-keys-dipping.png 2038w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p>When I looked inside I could see that the hammers were elevated as well.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Hammers-Raised.png\"><img loading=\"lazy\" decoding=\"async\" width=\"783\" height=\"1024\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Hammers-Raised-783x1024.png\" alt=\"\" class=\"wp-image-387\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Hammers-Raised-783x1024.png 783w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Hammers-Raised-229x300.png 229w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Hammers-Raised-768x1005.png 768w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Hammers-Raised.png 1142w\" sizes=\"auto, (max-width: 783px) 100vw, 783px\" \/><\/a><\/figure>\n\n\n\n<p>I checked all the usual issues such as a foreign object, regulation settings, friction, etc. I checked if perhaps the player piano mechanism was the cause by resetting it. I took the whole piano apart and could find nothing out of the ordinary. At these times I often remind myself &#8220;Pianos must obey the laws of Newtonian physics.&#8221; meaning that even when it seems like there is a ghost in the machine everything must have a logical explanation. A key is a simple lever and if it is depressed something must be applying force to it.<\/p>\n\n\n\n<p>I contacted several other technicians including the manufacturer to get their thoughts. Everyone was stumped. Finally one of my trusted colleagues Nick Morris who specializes in player pianos mentioned a situation he experienced years before in which movers had screwed the leg bolts in too far and they interfered with the keys. I recalled the client had moved the piano recently. I called the client and asked him if there was any problem with the leg bolts. He said the movers had lost the bolts and it took them a long time to find replacements. This sounded like a strong theory. <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Underside-2.png\"><img loading=\"lazy\" decoding=\"async\" width=\"822\" height=\"1024\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Underside-2-822x1024.png\" alt=\"\" class=\"wp-image-395\" style=\"width:487px;height:auto\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Underside-2-822x1024.png 822w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Underside-2-241x300.png 241w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Underside-2-768x956.png 768w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Underside-2.png 1150w\" sizes=\"auto, (max-width: 822px) 100vw, 822px\" \/><\/a><\/figure><\/div>\n\n\n<p>I inspected the interior of the piano again and saw that the leg bolts were indeed protruding inside the piano. Now I had a smoking gun.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/2-Bolts-Protruding-Cropped.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1020\" height=\"897\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/2-Bolts-Protruding-Cropped.png\" alt=\"\" class=\"wp-image-383\" style=\"width:489px;height:auto\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/2-Bolts-Protruding-Cropped.png 1020w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/2-Bolts-Protruding-Cropped-300x264.png 300w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/2-Bolts-Protruding-Cropped-768x675.png 768w\" sizes=\"auto, (max-width: 1020px) 100vw, 1020px\" \/><\/a><\/figure><\/div>\n\n\n<p>What had happened in this case is that the movers lost the bolts, ordered the wrong bolts, then used high powered tools to force them which stripped the threads. Never hire regular movers to move your piano. Here you can see a comparison of the correct bolt which is the shorter one vs. the incorrect bolt which is the longer one. Notice the movers added five washers to try to make the longer bolt work.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Comparison.png\"><img loading=\"lazy\" decoding=\"async\" width=\"836\" height=\"1024\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Comparison-836x1024.png\" alt=\"\" class=\"wp-image-394\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Comparison-836x1024.png 836w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Comparison-245x300.png 245w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Comparison-768x940.png 768w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Bolt-Comparison.png 1142w\" sizes=\"auto, (max-width: 836px) 100vw, 836px\" \/><\/a><\/figure>\n\n\n\n<p>Now the hard part began &#8211; removing the bolts. Normally removing leg bolts is easy and can be accomplished with modest tools. I tried with my normal wrench and found that the bolts would not budge. Therefore I aquired a &#8220;cheater bar&#8221; which was nothing more than a 36&#8243; metal pipe. This tripled my leverage.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Cheater-Bar-In-Action.png\"><img loading=\"lazy\" decoding=\"async\" width=\"820\" height=\"1024\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Cheater-Bar-In-Action-820x1024.png\" alt=\"\" class=\"wp-image-389\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Cheater-Bar-In-Action-820x1024.png 820w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Cheater-Bar-In-Action-240x300.png 240w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Cheater-Bar-In-Action-768x959.png 768w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Cheater-Bar-In-Action.png 1142w\" sizes=\"auto, (max-width: 820px) 100vw, 820px\" \/><\/a><\/figure>\n\n\n\n<p>Even with this added leverage the work was grueling. Every turn took all of my strength. What should have taken minutes took hours. When I got to the last bolt, which was the most difficult of all, the bolt was so resistant to turn that it tore the screws out of the plate. <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-14-at-2.51.50\u202fPM.png\"><img loading=\"lazy\" decoding=\"async\" width=\"825\" height=\"1024\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-14-at-2.51.50\u202fPM-825x1024.png\" alt=\"\" class=\"wp-image-386\" style=\"width:526px;height:auto\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-14-at-2.51.50\u202fPM-825x1024.png 825w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-14-at-2.51.50\u202fPM-242x300.png 242w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-14-at-2.51.50\u202fPM-768x953.png 768w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-14-at-2.51.50\u202fPM.png 1130w\" sizes=\"auto, (max-width: 825px) 100vw, 825px\" \/><\/a><\/figure><\/div>\n\n\n<p>The threaded female metal plate that the bolt was supposed to screw into was totally detached. Now I had a much more serious problem. In the video below you can see that the bolt and the plate are married together but totally detached from the wood inside the piano.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Piano Leg Bolt Plate Stripped\" width=\"557\" height=\"990\" src=\"https:\/\/www.youtube.com\/embed\/-HW9lgZ3ENw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>The only way to remove the leg bolt from the female plate would be to secure the plate somehow so that it would not turn. However you can imagine that with 36&#8243; of leverage the amount of torque being applied was substantial so stabilizing it would be next to impossible. I tried many strategies including vice grips, clamps, even fashioning custom tools in my shop. All of them failed. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/All-Tools.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"714\" src=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/All-Tools-1024x714.png\" alt=\"\" class=\"wp-image-393\" srcset=\"https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/All-Tools-1024x714.png 1024w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/All-Tools-300x209.png 300w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/All-Tools-768x535.png 768w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/All-Tools-1536x1070.png 1536w, https:\/\/www.lapianotuning.com\/wordpress\/wp-content\/uploads\/2025\/04\/All-Tools.png 2032w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p>Now it was time to go to the last resort which was cutting through the steel bolt and replacing the bolt and the plate entirely. I acquired a tool known as an &#8220;angle grinder&#8221; which is capable of cutting even the hardest steel.

First, never use regular movers to move your piano. I wish I could say this story was unique but I get calls like this all the time from customers who&#8217;s pianos were damaged by movers.
