Rhodes Piano Mortise Sizing Cauls (Key Bushing Plugs)
prusaprinters
<p>I designed these Cauls in Fusion 360 when restoring my Rhodes MK1 Piano earlier this year.</p><p>I took inspiration from <a href="https://www.nolapiano.com/blog/tag/Key+Bushings">here</a> and several other forums & YT-Videos.<br>See the plugs in action on Youtube <a href="https://youtube.com/playlist?list=PLd0gfBIwizcNuarFYkLRpGKBe-NVYeg3D">in this playlist,</a> where i collected some clips from my restoration.</p><p><br>You can customize all relevant parameters in Fusion 360 as a parameter (see screenshot).</p><p>By that you can use this one file to create plugs<br>… for keeping the holes in shape after removing the felt with steam<br>… for installing the felt on the 1st side<br>… for installing the felt on the 2nd side.</p><p> </p><p>Update:<br>I added single shouldered and double shouldered plugs with various widths ranging from 3.00mm to 4.20mm, so you don't need to use Fusion 360.</p><p><br>Ideally, you print 20 or more of the same kind, so that you can work in batches.<br>I had to play around with the dimensions until i found the right thickness for my felt.<br>The restoration worked perfect for me, my keys have now little to no play while still being easy to press.</p><p>Print settings:<br>Any hard filament such as PLA or ABS.</p><p> </p>
