It will save you a lot of time and playing about. No you are not a cowboy. You are learning and we all had to start somewhere. When I started I'd never seen the workings of a clock or watch.

My boots are ostrich, my hat is not a Stetson but it is ornamented with a Buffalo Nickel hat band, and when I want accuracy, I carry my vintage Winchester Model 94 30-30!

Back to clocks...the modifications to the suspension spring worked. It is now running slow with the pendulum fully extended. I will set it at mid position and test today

Well, right now I dont have the next size down, and I am a cowboy!

 

Oh Roy surely you're not wearing spurs in the house, it ruins the carpet. How's Trigger lol.

Even cowboys 🤠 can repair LWS. 👍

A short update: I have been able to test the extremes of the pendulum and proven that I can make it too fast or too slow, so I will be able to regulate it.

Are talking about cattle or the other species that is impossible to understand?

Correct but it has a particular cultural reference...having not grown up in USA or watched US TV, it would be tough to get this one.  Hint: Clint Eastwood.

It dawned on me this morning that I can speed up my calibration by figuring out how many periods of the pendulum cause one full rotation of the minute hand!  This was a blinding glimpse of the obvious for me, old hat for you old hands at this.

Escape wheel has 20 teeth.  The pinion on the escape wheel has 8 teeth and the minute wheel has 96 teeth, so it takes 12 rotations of the escape wheel in one hour.  The pendulum must oscillate 10 cycles for one rotation of the escape wheel thus 120 periods of the pendulum to turn the minute hand one hour.  So that means that in one minute the pendulum rotates two full periods.

I just count the periods while timing with a stop watch...that will get me close!

Clock is running great!  Got the 10th edition of the T book and have done some comparisons.  I believe my clock is plate 1574A.  It appears identical to 1579 except for the suspension spring size and length.

I remember donkeys years one I was working on the s/p according to the book was wrong I made a note of it in the book. It is more then likely the same thing has happened to you. Nice to know you have sorted it and the clock is working well.

Donkeys years ago not heard that phrase for a long time 😂

Well done LWS  persistence pays off, The books are not always right due to typo's etc but I still maintain the 10th Ed is a must for these clocks,  but as you have found out not perfect.  again well done.

    • Welcome to the forum, enjoy. 
    • Yes, the specific old tools do exist, but may be having one is not needed as they are not cheap, and also You will be able to do without it well enough. My advice will be to use regular depthing tool and adjust it for the exact distance between pallet fork and escape wheel bearings from the watch. Then remove the shellac from the pallet that now doesn't pass the ew teeth and move this pallet in. Then put the pallet fork and ew on the depthing tool and check how they lock. They should not lock when the pallet is in, but You will little by little move the pallet out and locking will appear. Then move just an idea out for reliable work and apply shellac, then check if things are still the same. You have to observe where the teeth fall on the pallets - it must be just a little below the edge between impulse and rest planes. Then You must check how everything behaves in the movement This Potence tool is so ingenious, but actually, the traditional way to do the things is much more simple. Arrange the parts not on the pillar plate, but on the cover plate. Only the central wheel will remain on the pillar plate, secured by the cannon pinion.
    • There is a tool that was made for setting up and adjusting escapements of full plate watches.  There were two styles, the picture below shows both of them.  The lower tool held a movement plate and the vertical pointed rods were adjusted to hold the unsupported pivots of the lever and escape wheel.  There was also a version of this tool that had 3 adjustable safety centres so that the balance pivot could be supported by the tool :  The other version I’m aware of is the Boynton’s Escapement Matching and Examining Tool came as a set of two or three clamps that gripped the watch plate and held the safety centres for the pivots : These do turn up on eBay from time to time.  For some escapement work, you can set up the parts in a regular depthing tool, with the centres set according to the distance between the corresponding pivot holes on the movement.  I hope this helps, Mark
    • Once you are aware of the problem, you can adjust as necessary. I have a couple of the Omega 10xx, and they are not my favourites. They seem a bit flimsy and not as solid as previous generation Omega. But I think that's true of a lot of movements from the 70-80s. For me, the 50-60s is the peak in watch movements, where the design criteria was quality, not saving the last penny.
