    Making spade drills

    Are you talking about carbide twist drills?
  2. It seems I have been defeated so many times already that I don't even care anymore - Spent 5 hours making a new component, only to ruin it on the last operation? Just start over. The second time you can do it in 4 or 3 hours anyway. - Bent hairspring by catching it on center wheel again? Learn to be more careful and spend 2 hours spring-tweaking under the microscope. Even more fun if it's a ladies watch. - Some part pings into oblivion? Scout for new one on ebay. I actually force myself to purchase a new (old) part as a form of self-punishment, even if the watch is not worth the expense (unless extreme, hehe). One part of learning watchmaking is to stay calm in the face of soul-crushing defeat. A few days ago I assembled and cased an ETA 2824 in a miserable front-remove case. The watch ran great on the timing machine without the automatic module installed. I installed the module, closed the back and wore it for testing -- and it stopped after just a few minutes. I haven't quite figured out what's wrong, but if the ratchet driver wheel of the automatic module exerts pressure on the ratchet wheel, the wheel train loses power somewhere. Most likely there's something wrong with the barrel, or the intermediate wheel. So, start from scratch! Cheers! Rob
  3. Yep, this is what ended up working Super annoying case design.
  4. The movement can't be installed from the back because the dial is too big. So the movement has to be installed from the front, then the glass fitted. Then the stem is installed and the back is closed. I took some more piccies: 1) Original crystal that is only held (lightly) by the dial itself. Totally incorrect.. 2) Without crystal. Bezel fitting is normal V-shape that should take a normal slanted bezel. 3) New bezel lying loosely on top of watch 4) Back of watch
  5. Sure! OK. I tried searching for permutations of "[cheap] glass assortment", but haven't seen anything so far. Cheers! Rob
  6. I have a generic ETA 2824 watch that came with a completely incorrect and ill-fitting acrylic crystal. It's a rather annoying case design that removes the movement via the front, so a crystal lift is required. The back also needs to be opened, to release the stem. I ordered a new Sternkreuz HW high-dome crystal from Cousins, thinking that I could use my lift to insert it, but the dome shape is too slanted, and the lift won't grab it. My lifter is a old-school version of the modern Indian/Chinese ones (as pictured below) -- probably older than I am. Does anyone know what kind of crystal model I need to order for use with a lift? Question 2: Has anyone tried the cheaper high-dome crystals Cousins offers? They are called "DPA watch crystals". I normally install Sternkreuz N-series low-dome crystals.

    Oil cups

    Interesting.. I wonder if I should try to get a few single cups instead. For rarer oils (like braking grease), it doesn't matter if it's in a 3-cup hard plastic oil pot. Old oil cups are not that easy to find though. For funsies, I had a look at Cousins. Single cup, glass wells, Bergeon is 14.50. That adds up quickly. Single cup, plastic, A*F: 23.50. Wow.. Perhaps I should just stick with 1.50 single cup Indian ones, and teach myself to stop stabbing chips off the cup wall

    Oil cups

    Well, that didn't work out.. I received a set from China, and it turns out the cups are made of plastic -- some sort of nylon (see picture). That's even worse than the hard plastic ones I'm using at the moment. The seller clearly stated that they are agate cups and apologized for the incorrect description (probably just copied from another seller anyway). Working out a resolution now, sigh. At least he's responsive. So now I'm very hesitant to buy another set from ebay, since I don't want to run into this issue with another seller as well.

    feintaster tool .

    I'd probably replace the whole base plate.. My feintaster looks the same, but with blue velour. I always had mixed feelings about the stuff, since it's a dirt trap, and I'm not sure if it's that great at trapping dropped parts (which I assume is it's main purpose). I wonder what would work better as a replacement.. Leather, like you suggest? Some sort of silicone sheet? Chamois? Anything that stops the part from bouncing.

    Interesting tip

    Ah, I remember reading that somewhere as well. Great to dab away the excess whale oil! Terrible idea in the modern age where a pack of rodico costs just a few bucks and lasts for ages..

    ETA 2824-2 Stem Question

    Lol! I remember replacing one of these some time ago with a square one that I had to file down in the lathe. I thought some gorilla had twisted it, and remember being puzzled that no teeth in the setting path were destroyed. Good thing this is one of my own watches! I still have the old stem, so it goes back on the todo list I'd never heard of a helical stem until you mentioned it! What could be the purpose of it? Perhaps to increase pressure on the setting wheel, when setting the hand? Doesn't seem worth the more difficult production process. I'm assuming the sliding pinion is also helical? (Sorry, kinda off-topic)

    Oil cups

    Great, time to get a set Cousins is much more expensive at 35 UKP, plus shipping vs 28 USD including shipping on ebay. The proper bergeon one is 90 UKP, which is not even as much as I expected. The full metal one is 260 quid though, lol

    Oil cups

    Currently, I'm using the hard-plastic type of oil cup that has three reservoirs with one lid. Works fine, but is prone to scoring a bit if you stab them with an oiler. Last month I did exams at the BHI, and they had very nice Bergeon metal agate-cup oilers with individual lids. On ebay I found a Chinese version that seems OK -- but has anyone here used a set of these? (This link is link is just one of many sellers with the same product, as usual) https://www.ebay.com/itm/Black-New-Oil-Cup-Stand-with-4-Agate-Containers-For-Watchmaker-Watch-Repair-Tool/292568705943 Cheers!

  14. I did D16 (automatic service) and D18 (watch theory II). Both went pretty OK
  15. I bought the what looks to be the same "Bergeon" set from a watch fair in Holland. The seller had even put a nice yellow Bergeon label on the box. It was a good deal and it works great, but it isn't a proper Bergeon. I don't particularly care, but I was kinda miffed that I fell for the scam. As others said, this only winds in one direction. Another problem with it is that the arbor sizes are rather large. I was trying to wind in a 2824 mainspring yesterday, and the winder arbor size was twice the diameter of the barrel arbor (and would completely stretch it). I wonder if a proper Bergeon set uses much thinner arbors. Sometimes I fall back on my trusty old winder, which has the benefit that it's much easier to make new arbors for. The hook on my new arbors allows winding in both directions. I've also drilled out the hook in existing winder arbors in the same set in order to replace them with a bidirectional variant. One of the arbors I made before was perfect for winding the 2824 spring. I've added some pictures of the old set and new arbors below. Cheers! Rob
