I've read severat threads here about stop works and what they are used for, however I am not able to understand how they are set so that I can wind up a new cable.
Can anyone help?
Thanks so much,
You shouldn't have to adjust it. From the photo it appears to be in the fully up position. Release the click and wind it down to the fully down position. Remove the plastic cable guard and attach the new cable, usually with 3/4 to 1 turn on the drum? Put on the weight and wind er up ... that's it. It's best for the movement to be on a stand but the outer cables can often be replaced with the movement in the case.
Also, it's a good idea to compair the up and down positions of your weight with the new cable with the other weights, just to make sure the up and down positions are about the same.
I feel the best place to set the stops is at the top of the wind and at a point just before the weight has a chance to run into something. Others feel it's more important to ensure the weight can't hit the case bottom and allow the cable to loosen on the drum. Ideally, if the stop is correct for the clock, it'll stop before either extreme is exceeded.
The quickest way is to just install the gears and start winding. Somewhere along the way, it'll stop. Slide the gear off the winding arbor (While preserving its orientation and position) and wind the weight to the point where you want it to be stopped and reinstall the gear. Let it down and see where it stops at the bottom and wind it back up, again. If you see something you don't like, it's usually just a quarter turn adjustment, one way or the other.
