In Electric Clocks
Hi Steve, Work has let off a bit and over the weekend I managed to get the pendulum electric clock dialled in. I actually used all of the techniques for minimising friction that you mention for the pendulum wall clocks and hence my amplitude is rather large and I had to have a few goes at tweaking the length and position of the static and active paws. I am now pretty sure that I do not get any "2 second" pushes which would make the clock run fast. I will be checking this over the next few days. It actually looks really great. However, with the pendulum bob all the way at the bottom I am seeing the clock running about 1 to 2 minutes fast for every hour. Assuming that I do not get any 2 second pushes I'm really not sure how to slow it down because the period of the pendulum is governed by the length of the pendulum and I cannot take the bob any further down. Any ideas?? Krys S

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.
