Hi folks. Long time no post. Having a baby means there is less time for watches :(

Does anyone know the lift angle for the Bulova 10A series of watches from the 1920s. I'm trying to get an accurate reading on a movement I'm repairing. In particular I have a 10AI. I couldn't find the lift angle anywhere so I tried to calculate it using this method. The result was 59 degrees. But that seems quite unusual...

Should think you will be fine with using 52 degree . I have never seen a movement that has 59 degree lift angle . If you look at the other Bulovas they are around the same . 50 -53 . There would not be much different if you set it to 50 or 52 degree .

Thank, yes I spotted those on the lists. There seem to be a set of 10s that are very different. All from them 60s. Mine is from the 20s. It's similar to this:

Thanks for your advice. I think I'll just leave the machine on the default 52 and see how I go :)

      Epilame / Fixodrop

      I kind of think the same, the surface under the oil is the same as the surface around the oil. Can epilame both repel and attract , that doesn't quite make sense in simple terms, but is it more complicated than that.

      I agree with @JohnR725. Oil on an epilamed surface is essentially the same as water on a waxed surface. The same physical properties are at work (surface tension vs. adhesion).

      Without Our Forum

      By Waggy · Posted

      I think we all get a lot out of this group, and it has been pivotal in my development by the sharing of knowledge, experience and learning from more seasoned experts such as @JohnR725 and others (you know who you are!) as well as fellow novices. I think that having a backup communication plan in reserve so that if there is a future problem just makes good sense. I don't think anyone is trying to undermine the forum, but if something unthinkable happens, like the Ranfft website for example, then it would be good if those who are willing can still keep in contact. Speaking personally, and I know I risk a charge of heresy, it would be good if Mark could be a little more visible in this forum, and maybe give any insight from time to time on the future/progress of forum and instructional videos etc. even if its just to confirm the status quo. I appreciate he is a busy man with a full time job, but so are most of the rest of us and to post a few lines every now and then shouldn't be too much to ask to reassure the restless villagers. Best outcome for me would be a message saying something along the lines of: "Hi guys, all good, no planned changes... enjoy the forum, will message again next month!" Just my two cents.

      A nice looking watch !! Did you try 9010, instead of the 9415, on the pallet jewels / escape wheel? And if you did, did you notice a difference?

      Knocked out another 404 last night...when you are in the zone! This watch was a non-runner which I picked up as part of a lot of 8 watches, so works out to be $3.12 per watch. Before:   And the finished watch, new crown and stem and the crystal was cracked so was replaced. I also replaced the mainspring as the original was the old steel type spiral and very 'set' - all else is original: The Movement was a AS 1686, but in reading around a little the ACCRO watch company were sued for their use of the five point crown on their Jacques Pere range as it resembled Rolex, see below: ACCRO then reverted to just ACCRO on their watches - I have done some sniffing around the internet and haven't seen another example of ACCRO and the crown together on a dial so maybe I have something unusual, or maybe I was looking in the wrong places 🙂.
