  1. Does anyone know if the Elgin mainspring 4935 for size 22 aircraft clocks were ever made in alloy? So far I've only come across blue steel ones and I don't know if because alloy ones are just rare and hard to find, or they were never made. This is for an Elgin Pioneer / A11 aircraft clock. The Height is 5.46mm thickness is 0.215mm length 26 1/2 inches, so not a size that Cousins stock. The old Blue steel spring is still ok to reuse but if possible I would rather replace it with an alloy spring.
  2. Nice, I have thought about doing something similar as I have a couple of spare Raspberry Pis with displays and a couple of laser diodes lying around, but on the list of tools I still need to make a hairspring vibrator is pretty far down on the list. For pure tool porn you can't beat the look of the old fashioned hairspring vibrators though.
  3. To me a fake is something not made or authorised by the original maker. There are levels of 'fakes' the Swiss made pocket watches to look like they were made in the USA, but weren't and were much more cheaply made. If sold as a watch made in the USA you could call it a fake. If sold as a Swiss watch in the 'American Style' I wouldn't call that a fake, but it could still trick some buyers into thinking they were getting something the aren't. My post was more about modern fakes. Either something made within the last few years to look like its much older, or a genuine old watch / clock modified to make it look like its more valuable than it is like the post above with an old watch fitted with a new dial to make it look like it was a German military watch. Then you get homage watches that can fall into a grey area.
  4. Watch cleaning solutions

    I use 20% turps and 80% Shellite (Naptha) for my first rinse and %100 Shellite for my final rinse. I use this in jars in a water bath in my US, but I keep a close eye on the water temp. If it gets close to 40C I tip it out and put fresh water in it. I don't like the Shellite (Naptha) getting too hot, and I do this in my workshop, not my house. I stay away from Isopropanol (dentured alcohol) as it can dissolve shelac and its hygroscopic. You should be able to find Oleic acid at a local chemical supplier, but you may want to team up with other people as they probably will only want to sell it in bulk rather than olive oil. As a side note Oleic acid is also used for cleaning clocks with water based solutions.
  5. Watch cleaning solutions

    Well isn't that what cleaning watches is all about, getting rid of unwanted bumps and S**T.
  6. Watch cleaning solutions

    I don't make it so I don't have the exact percentages, but a good starting point is reading the MSDS for your favorite cleaner, they give the chemicals but only approximates of the percentages. Here is a good place to look. http://lrultrasonics.com/msds/index.html
  7. Watch cleaning solutions

    For hobbyists, Shellite (naptha) and pegwood sharpened to a point will do for sure. As you say it all comes down to time and money. If you have a lot of time save money, if you don't spend some money to make some time.
  8. Watch cleaning solutions

    At my watch school we make our own cleaning fluids based on the commercial ones. To be fair Oleic acid is not the same as olive oil, yes olive oil is around %80 oleic acid but calling it olive oil is like calling crude oil petrol. Yes the commercial fluids are way over priced, we make it for around $10 to $12 a litre compared to $30 a litre it sells for in Australia, but finding places that will sell you monoethanolamine and Propoxyethanol isn't easy, we could not find suppliers for both of them in Australia and had to import them.
  9. Just noticed the seller has it as a private listing, so you can't tell if its actually 24 separate bids, or just the seller with 2 fake accounts he has used to bid on his own item to make it look like it is hotly contested so it might trick someone into thinking its worth bidding on as 24 other people already has. If no-one wins he just cancels the sale and hasn't lost anything
  10. Tap and die

    Elgin and Watham made their own thread sizes for their pocket watches so you cant buy new taps and dies to fit their old watches. You need to find an old set off ebay when they turn up that are hotly contested. Guessing the newer wristwatches made by the Swiss branded as Waltham and Elgin used metric threads
  11. I think this Pocket watch falls into the topic above. Printing on the dial looks crude which set off the first alarm bell, but a watch advertised as being made during WWII for the German military with the words in English 'Made in Germany' on it? Come on! https://www.ebay.co.uk/itm/OLD-WW2-Years-GERMAN-Military-POCKET-Watch-Serviced/282823850130?hash=item41d99d7892:g:hz8AAOSwL9paa2pj Yet another case of a cheap old watch been fitted with a new dial trying to be something its not. Anyone got any other obvious bogus watches they want to add to the list?
  12. Yes other than different sized arbors its complete, but if you have access to a small lathe they are easy enough to make. If you have the money consider getting an Ollie Baker style mainspring winder. I have one identical to what is in your picture but have just ordered myself an Ollie Baker style mainspring winder
  13. Anniversary clock suspension

    Just adding my voice that the 400 Day Clock Repair Guide from Holovar is a sound investment and you will struggle fixing 400 day clocks without it.
  14. Elgin Pioneer 8 Day Aircraft Clock

    I've ordered the A11 repair manual and I'm waiting for that to arrive before I do anything else. I also had a win searching the National Archives of Australia and found the title of a document. ' RAAF - Court of Inquiry - Loss of Pioneer Kollsman Clock (3310-2-A-4806) from Wirraway A20-109 at Laverton about 24/10/1940 ' So I now can confirm that these clocks were used in Wirraways which gives a lot of weight to this clock being from the Wirraway A20-343
  15. Elgin Pioneer 8 Day Aircraft Clock

    I've found a few example of Elgin A11 clocks which look almost identical to this clock. I think the A11 was the evolution of this clock and repair manuals are available for them for a few dollars. I may invest in one before proceeding any further, would hate to break something on it. Oldhippy are you saying set the plat up on an open vice and use a stake fine enough to tap out the shaft from the wheel? I've done this before on stuck cannon pinions, but never on something this fine, or valuable.
