Working on a Kienzle Westminster clock and thought one issue was a broken mainspring but found this. Has anyone come across one of these arbours and how do they work.

Sorted sorry no picture of the pin but when I tapped the arbour to remove the lid of the barrel a tinny pin dislodged which I have found on my worktop. It sits here. With a google search it is suggested that this design was to allow removal of the barrel without splitting the plate. This Kienze movement is very unusual  it has two clicks for one on the mainsprings. See pic.

Hi  I have had something similar where the arbour slips out and the barrel is removed without disturbing the plates but no piece of spring.  The second click appears to have no spring to engage it is that correct or has it been removed.

I worked on a similar Kienzle movement before. In fact, it was my very 1st chime movement. 

The arbor has a locking pin as you have discovered. I found it very convenient as it was easier to remove the barrels.

The chime barrel indeed has 2 clicks. Yours might be missing one of the springs as the one I worked on had two springs. Perhaps it's because the chime mainspring is so strong that they felt it needed a failsafe.

Yes the picture was taken after I had removed one of the springs. I just could not release the power and lift both clicks at the same time. I presume the arbour can be tapped out while the barrel is still in the clock, if so this one was very tight indeed.

The retaining pin that I remember didn't look anything like yours. It was a round polished steel pin. So the arbor could be pulled out quite easily after removing the ratchet wheel.

This clock was worked on by the customers farther who tried to not get it running but failed. So it’s just a sentimental clock repair that he wants to see running. But all sorts of scratches, brushed screws and other damage and of cause copious amounts of WD 40 around the movement. So a big challenge but I promised I,ll give it my best attention. 
PS another challenge I have raging tooth ache at present so difficult  to concentrate. 😡

Haha. I could help you with your toothache but I'm on the other side of the Earth.

Call your dentist for an emergency appointment. In the meantime ....

If it is a gum problem, rinse with warm saline 3 to 4 times a day.

If it is a nerve problem, take a mouthful of cold water and hold it for as long as possible.

If it's really bad, take an OTC painkiller as directed.

Thanks I have an appointment this afternoon. I have been rubbing in a sensodyne toothpaste onto the tooth which has eased it a great deal.

This is a system that is used so you knock the arbor out so to release the barrel complete without taking the movement to pieces. Just don't lose that pin. A double click is a safety thing in case one breaks.

Thanks. I have now cleaned springs etc and now clean the winding part of the arbour now  pulls out without too much effort. As you say the pin is small. Its another part of the none ending horological learning curve.

      By tonydagee · Posted

      Hello all, just disassembling to service, but I can’t figure out the working of the calendar work…it’s not operational the jumper and spring are ok, but the operation of the driving wheel has me at a loss. I can’t see a cam to drive anything. Is something damaged or missing? Help please!

      Unusual Seiko dial damage

      Believe the relume (not a fan) was done a long time after the damage.

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
