- Pendulum weight - NAWCC Forums
The weight of the pendulum is not a factor in the equation The formula also assumes a free swinging pendulum with a frictionless suspension and no air resistance Also, the length is not the overall physical length of the pendulum but the distance from where the pendulum is 'hinged' to the center of mass The mass is concentrated in the
- Adjusting the length of the pendulum - NAWCC Forums
I've taken an Edisonian approach to finding the right length of a pendulum in order to make a mechanical clock a good timekeeper I suppose I could take an ab initio approach and count pinion leaves and wheel teeth to obtain the proper length, but that would probably still require me to adjust the position of the pendulum bob Frankly I don't
- Problems with pendulum suspension and rotation - NAWCC Forums
This Clock has nothing to do with Asia, it is a Regulator completely made in Portugal in the 50s-60s In Portugal there was a tradition of watchmaking that began in the 19th century with pendulum and tower clocks
- Pendulum fails to keep swinging - NAWCC Forums

- Pendulum stops after 10-15 minutes - NAWCC Forums
Ok, we have finally reached the point of this post The clock’s pendulum stops after about 10-20 minutes I have read up a bit on this I have listened to the tick tock and it sounds even to me - like a metronome However, the pendulum does swing in a diagonal back to front motion rather than just side to side
- Compensated pendulums - NAWCC Forums
On a "simple pendulum" setup this would cause the pendulum's period of swing to lengthen (slow down) Mercury compensating pendulums contain one or more glass or metal flasks partially-filled with mercury as counterweight When the mercury expands, it moves up inside the flask(s), counteracting the lengthening of the iron pendulum rod
- Seth Thomas Grandfather Clock Pendulum Suspension
I have a ST grandmother clock that needs a pendulum suspension The original part was missing when I bought the clock that also had a broken suspension spring The distance from the suspension spring and the top of the inside of the case is ~7" Timesavers sells a universal pendulum leader that is 7 1 8" long
