Special Shopsmith Hack, Watch Tinkering Bench

#273194 by nuhobby » Thu Aug 13, 2020 8:30 am

I have been amateur-tinkering with wristwatches for about a year now. There is a lot to learn, particularly in the mechanical realm. It's just a hobby and I'm not certified or trained. It can be very fun, as well as most frustrating at times!

One aspect of the work has greatly improved this week. I got my work surface elevated close to chest / neck height, provided I use my work-seat. This is a specially designed fixture that sits nicely on my 510-worktable, and can be removed easily. The work posture and work ergonomics are much better than I've had before:

Also, as a reminder of some of my earlier posts... The PowerPro 250 RPM setting opens up a number of opportunities for watch-bezel finishing, even watch-bezel painting as I did last Christmas :)

Using Shopsmith for Turning Acetal (Delrin)

#275081 by nuhobby » Tue Sep 29, 2020 1:23 pm

Further into the watch-tinkering stuff....

I had got a mish-mash of Asian-sourced watch components and a movement which I wanted to build into something working. However in my case, the subject watch-case was designed for a thicker movement than the one I wanted to use.

Reading up a bit, I'd seen the use of Acetal (Delrin) spacers from watchmakers with Taig lathes and the like. But elsewhere I saw that some wood-lathe folks had turned acetal successfully for their pens and small projects.

Challenge accepted, and first proof of concept!

Here is some 1.5" acetal chucked into my 4-jaw:

Here is the rough outcome, which was not bad; I did keep it, and I hand filed it a bit more after this:

Here's the watch-in-progress, where the stem finally inserts correctly, now that the movement is spaced 'down' a tad relative to the crystal:

Have a great week!

Next up, the acid test!
The real movement arrived and was fitted with new hands. Once everything seemed to run well, I went ahead and mounted it up in the case. I'll do more run-in testing and adjusting, then it should be worthy to seal up for use!

P.S. I also need to trim the length of the winding stem, still.

I don't know much about watches but I do like the tinkering bench idea. I think I will add one of those to my shop, not for working with watches but for other things that I do play with. Well I did find a watch that I could try and take apart just to see what makes it tick, but, well it doesn't tick and doubt it ever will.

It does say water resistant but this one must have had some shock as the little hands are loose inside....... and it is very weathered. Well it would be a nice first project for a tinker bench.

What is the green material? I have a left over sheet of self stick felt that is just sitting around so I was thinking that might be an option but then what you are using interests me....

Ha Ha! We work with what we must!

Yeah, that green mat is a specialized non-skid work mat from Bergeon. I maybe could have improvised with something else, but that seemed to be "the bee's knees" among watch experts. No complaints, and it's replaceable.

Keep tinkering!
