Hi Steve.
Have now printed all of the parts for the new Pendulum clock.
I really like how you designed the way the small gear 2 fits onto the main ratchet. Very neat. I also like the way that you have made the option of using screws rather than a press/tight fit. I always found the tight fit to be tricky to get correct.
I have installed the electronics and have successfully had the pendulum swinging for the last 48 hour. The amplitude is quite large and will certainly look great. I have now started to try and put the thing together.
I have a few questions as I am having problems with measurements and getting the basics of the clock together.
Tonight, I wanted to get the centre gear cluster and the pendulum together to see how the thing fits, however, I am having some problems.
My first questions refers to your drawings and 75mm arbours. I have cut all of the arbours and I was under the impression that the 4 x 75mm long arbours/rods are for connecting the front legs to the main front dial. In your drawings you mention 75mm arbours but never mention the 95mm arbours which I have cut three of???
The 95mm main 3mm arbour seems to be too long?? Before shortening it, I thought that I would ask your opinion. If I use the 95mm arbour with the bearings, I cannot bring the front of the clock together square with the bottom frame. Even if I just place the 95mm arbour without the bearings it still seems too long.
I hope that my above comments are understandable and make sense. If not I can send some photos.
Many thanks in advance Steve and hope that these questions do not take too much of your time.
Awesome.
I am not sure yet how the clock runs as the batteries age. My clock has been running for around two months so far. The amplitude is still quite large, but the intended application is to swing a pendulum without any worry about amplitude.
This clock seems to need a bit more tinkering than the stepper motor desk clock. You may need to give a set of pawls to each recipient with a few instructions on setting them.
