Fancy building harmonic mounts, Josh?

This dude has just done it. $700 USD in materials. Mind blown.

Well, not Harmonic drive mounts, Adam, but I will be building direct drive mounts after I've done one for myself


After a few prototypes, I've got a Working variable backspace adapter that Peter Ward was asking for.
The time is well over due to send it to him so he can test it out.


Cheers, Josh.

very cool, Josh.
Are those three grub screws the parts that drive the extension? Just thinking about any introduction of tilt if you had to do each one individually and you got one slightly wrong.

[Joshua Bunn (Joshua)]

Thanks Adam.
No, those screws are what limits it's travel, and stops rotation of the left and right hand threads with respect to each other. The 3 screws were Stefan's idea, I came up with the split outer ring design for the extension and locking, once at the required length.

Really like the idea of the Harmonic Mount suggested earlier, there's a challenge Josh
