Westminster chime and pendulum - NAWCC Forums As you can see in the picture, the pendulum is right in the middle of the hammers The pendulum measures 86 cm and has a 14 cm stem on the movement The chime is 57 cm long It will be set 8cm higher The end of the chime rods will therefore be 86+14+8-57=51cm above the lower end of the
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
Adjusting this Escape Wheel and Pallet | NAWCC Forums The crutch imparts energy of the palette to the pendulum This can be through a frictional connection (like yours) that has grip slide and can be adjusted Others use a wire that is bent to adjust The crutch doesn't really connect to pendulum The crutch loop pushes the suspension that holds the bob and pendulum rod
Beat Setting 101 - NAWCC Forums Scottie has pointed out that a regular pendulum clock is in beat when overswing is equal in both directions The same is true for torsion clocks A 400-day torsion clock is in beat when its pendulum has equal overswing in both directions Overswing is the amount of pendulum rotation AFTER a tick or a tock

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
Which way to bend the pendulum rod - NAWCC Forums The bent rod changes the location of the crutch with respect to the bottom of the pendulum's arc But I don't think it changes the relationship between the crutch and the verge, because, dammit, vertical is still constant Bent rod, schment rod, the pendulum still completes half its swing at exactly the same point it did with a straight rod
Verge adjustment question - NAWCC Forums But the "suspension point" of the pendulum being aligned with the verge pivot holds only for knife-edge or Cuckoo suspensions For more conventional pendulum suspensions, the "center of flexiture" of the suspension spring should be in line with the verge pivot so that the pendulum and crutch move in the same arc
