Hi-hat clutch

<p>I was inspired by a local drummer KJ Sawka [<a href="https://www.youtube.com/watch?v=b98BJ36K1wo">https://www.youtube.com/watch?v=b98BJ36K1wo</a>]<br/> and wanted to mount my 10" splash cymbal above my hi-hat for a more compact kit. Instead of<br/> buying more hardware, I learned CAD and designed this simple clutch in a few hours. This is<br/> the third iteration - the other two broke when wailing on the cymbal. This one is quite strong.</p> <p>Use an M4 nut and bolt to secure the clutch to the hi-hat shaft. If you don't have metric hardware<br/> available, a #6 or #8 machine screw will work too. Hand-tightening the bolt should be sufficient,<br/> but if the cymbal slips down the shaft, you can give the bolt a 1/4 turn with a wrench. My hi-hats<br/> are Gibraltar with a 7mm diameter main-shaft. If your hi-hats have a significantly larger or smaller<br/> shaft, then you may need to augment the design. I parameterized almost everything in the<br/> CAD file.</p> <p>=====<br/> Update, after 6 months the screw part broke. I re-designed it to be a lot stronger and moved the nut/bolt to the bottom.</p> <h3>Print instructions</h3><h3>Category: Music Summary</h3> <p>I was inspired by a local drummer KJ Sawka [<a href="https://www.youtube.com/watch?v=b98BJ36K1wo">https://www.youtube.com/watch?v=b98BJ36K1wo</a>]<br/> and wanted to mount my 10" splash cymbal above my hi-hat for a more compact kit.
