Possibly, its less the reduction, more the "stroke" of the vibration (ie how far the tuning fork moves backwards and forwards.) I think for a large tuning fork

I think for a large tuning fork, you _could_ use normal watch gears. However I don't have the skill to try that, yet.
- aidenn0 3y agoThat makes sense; the backlash needs to be much less than the tuning fork travel, right?
- KaiserPro 3y agoBacklash isn't probably that much of a problem, the orignal movement has a locking "pall" that stops backlash: https://youtu.be/CPS7aNCAwAA?t=161 https://youtu.be/CPS7aNCAwAA?t=161 scaling it up you'd get something like this: https://www.youtube.com/watch?v=u48n-jvo5N0 https://www.youtube.com/watch?v=u48n-jvo5N0 to make it practical on a tuning fork, that movement of the forks would need to correspond to the tooth size of the wheel. For a large tuning fork, its probably in the order of mm, so not beyond home shop manufacture
- aidenn0 3y agoA ratchet and pawl limits the backlash to the distance between the teeth on the ratchet gear; think of it this way; if it were to turn less than the radial distance between the teeth on the ratchet gear, backlash could still happen; similarly in regular operation, it turns the ratchet gear slightly more than that distance, and there is backlash until the pawl engages.
