Barrel bushing

Recommended Posts

I have a nice little carriage clock in for service, very good shape, except for over 0.30mm sideshake of the barrel arbor in the barrel. Thought I would show how I bush these; it seems they often get overlooked or just skipped as they are a little more fussy than just bushing a plate. I measure everything up, then remove the boss in the barrel, and make a bushing that fits from the inside and is stepped, replacing the boss. This way it's captive, and doesn't require a big interference fit to get seated and stay. I turn up the bushing with a boring tool in the lathe, doing the outside as well (running in reverse of course), then do the barrel opening with the same tool. It's a pretty quick process once you have the moves down!

Looks great! I don't have nice bezel chuck like that and have to use a WW faceplate and some precarious clamp positioning. Much slower to set up, but it works :)

How did I miss this? I always let the bush protrude by a tiny amount on the face side, then clean off, that way by the time you have finished cleaning up and polishing the barrel you wouldn’t see the bush. Nevertheless a good tidy job. We all have our own ways of working.

    • Not exclusively, no, but this was one of their major production sites until 1993. If the watch says Great Britain, or made in Scotland or Made in the UK, or UK Time Corporation, then it was made by UK Time Corporation (a division of US Time Corporation, the parent company of Timex) who set up in Dundee in the late 1950s, and also produced other items (the Sinclair ZX and Spectrum computers for example) at their Dundee site. During this time period, Timex also produced or used dials, mechanisms and so forth, made in France, Germany, England and even occasionally Switzerland. The majority of Timex watches for the European market were made in Dundee, but not all. https://en.wikipedia.org/wiki/Timex_Group https://en.wikipedia.org/wiki/Timex_strike Nowadays, like most volume producers, they manufacture mainly in the far east/China.
    • I figured it out. The point is to unscrew the crown and keep it in 0 position when pushing on the farthest/southern spot on the lever from the stem (close to the letter "p" in "push". Notice that the image above is when crown in position 2. 
    • Chemical recation between markers and dial? Is it a plated dial? Send an email to Zenith and tell them that you are a long term customer but are dissapointed; can you help? etc.
    • The other calendar. A Raketa, technically I'm younger whilst wearing this A tricky one to take a pic of as the dial is quite reflective.
    • the tools used to push the plugs In/out of cylinders.
