Sorry for the delay. Phone issues persist. Logged in earlier to see if my settings were off. Whatever the cause, now I’m not getting emails from the forum
Wow, 3 rpms! Awesome! How much weight are you using???
Number ratios look correct. Not 100% sure as it’s so easy to reverse the ratio by putting the driven gear first instead of the driver gear - speed vs. torque - depends on your perspective, I guess, but I trust you are correct.
I am curious how many actual gears this setup takes. For example, are your minute / hour hands running off the same 36-tooth gear powering the second hand, or are you using multiple drive trains? Does this added gearing increase the necessary torque and thus slow the rate of your escapement?
Maybe you could post a photo of the gearing (an incomplete build is fine) taken from the side?
If interested, my build #2 is actually quite easy to divide, so I can post images of just the second/minute/hour hand gearing. Likewise, when I separate it, the gearing of the escapement remains intact. (BTW: My escapement rotates at 12 rpms, 5 clicks per roatation.)
Let me know if I should bother with photos before disassembling, else I’ll probably just start over when I start build #3…
Also, not sure if you’very tried a worm gear, yet, but my minute hand is, as stated in an earlier post, running off a 60-tooth powered by a worm gear. 60:1 ratio with only two gears
Finally, I might be out of touch this week, but keep posting; I can’t be the only one reading these - LOL!
