  1. In case anyone is having trouble curing their UV cure products, check the UV curing light. Most nail curing lights are using UVA leds with a wavelength of 365 to 405nm. These tend to have a low output and some manufacturers apply higher currents than recommended to increase output. This unfortunately will shorten the lifespan of the LED. The bad news is it will still lights up but the useful UVA part of the spectrum is gone. Hence your varnish or glue won't cure properly. Another problem is using a dental curing light for curing UV gels. Our dental curing lights are actually using blue light with a wavelength of 450nm. There is absolutely no no UVA. It is designed to be safer for eyes. Hope this info helps.
  2. If your dentist uses this.... You better check his credentials.
  3. That's the old way. I advise everyone to try the UV nail varnish method. I got a bottle of luminous nail varnish from AliX. Each time I just take half a drop, put it in a mixing well and add Bergeon lume powder to get a brighter glow. No need to add thinner, rush to apply it before it dries out, then wait half a day for it to dry. With the UV method, you can take all the time you need, then cure it for 2 minutes in a UV nail dryer, clean up with alcohol and install the hands back on the watch. The only thing I miss is the smell of the thinner.
  4. One trick I learnt is to use balsa wood. Get a block of balsa and press the hand into the end grain of the wood until it is practically inlaid into the wood. I usually polish the hands by hand with Autosol using a piece of pegwood for rubbing. Knowing what the material the hands are made of is really important. Brass is very soft. Using too much pressure will bend it. Steels are brittle and can break, especially those hollowed ones for holding luminous paint. When using rotary tools to polish, use very low speeds and light pressure. I don't like dremel tools. I prefer to use a dental lab micromotor which has better torque, speed control and less vibration. Don't use tools that can catch the edge of the hands, like a cotton mop or felt. Use silicone polishers. I just can't work with conventional lume paste. The solvents evaporate so quickly that it's hard to get a smooth layer. I prefer using a UV cured paste. I use UV nail varnish and add lume powder to a consistency I like. Use a large oiler to spread the paste in 1 smooth stroke, using very light pressure almost not touching the hand with the oiler. Excess paste can be removed with the oiler. Then cure it in a UV nail dryer for 2 minutes.
  5. Welcome to the forum. I have 2 Bulova Accutrons. 1 working fine and the other a parts donor. After reading the service manual and watching a few YouTube videos on Accutrons, I don't think I have the guts to disassemble one. There is supposed to be an index wheel in there with teeth so fine and delicate that if the second hand is not fitted spot on without any rotational movement, the teeth could get damaged. There aren't many watchmakers out there who can service an Accutron. If you search the web, there is only a handful. Good luck in your seach.
  6. I couldn't sleep thinking about this watch. So I got up at 1 am to fix it. I agree with everything you said. There are days when it would take me almost an hour to get the gear train in. But tonight, everything went smoothly. It's ticking again. Let's see if it'll behave now.
  7. Had to take my Q Quartz apart to check. It stopped on my wrist 3 times today. Found quite a few magnetic particles stuck to various parts inside the movement. Being a quartz watch, I thought I've seen the last of my good friend - the contact spring. But lo and behold.... it's still here! Battling several technical problems at home and at work this week. It'll be some time before I can get down to putting it back together.
  8. It would probably be impossible to learn everything from this forum. There are many good watchmaking books available from Amazon and Ebay. Do get some of them to build up a sound foundation first. Jumping headlong into everything is not the best way of doing things. First learn the science behind metal working and machining. Learn the reasons why things are done the way they are. When you understand the science, then you can start to appreciate the intricacies of horology. Then you can start bending the rules and coming up with your own techniques of doing things. When you do get a lathe, don't go and try cutting a balance staff as your 1st project. Start with simpler things. Start with softer materials like brass and soft steel, then work your way up to blued steels and stainless steels. Be prepared to throw away many failures. Or keep them in a showcase to see how far you have come along in your journey.
  9. Yes. This is the video that prompted me to look into getting an automatic oiler again. Several years ago I asked my mentor about automatic oilers. His opinion was that it was an unnecessary luxury. He tends to be old school and even makes his own precision oilers from sewing needles. But recently I've been restoring pre 60's watches and they don't have shock springs. It's a real pain to lubricate such jewels. I don't know if any of you have this problem with steel oilers, but here in Singapore, it's so humid that if I leave my oilers uncapped on my bench for a couple of days, it'll start rusting. I might get one of these Chinese oilers as with the discounts and coupons, it comes to 1/3 the price of a Bergeon.
  10. The movement spacer has the number M64 on it. But from Dr Ranfft's website, it looks more like a M63. Anyway, the movement is running fine, accurate to about 3 seconds a day. So I decided to leave it alone. I only cleaned up the dial, relumed the hands and polished the case.
  11. Looks like it's time for you to get a jewel hole gauge, a watchmaker's lathe, cutters, files, burnishers and start polishing down your pivots.
  12. When I broke my 1st hairspring while trying to lever the collet off, my mentor said; "Good. Remember what you did wrong and don't do it again. Now move on."
  13. Has anyone tried out the automatic oilers from Alix? Are they useable? SG$ 51.72 35%OFF | Automatic Watch Lubricant Oiler Oil Pin Pen Precision Oiler Pen Pin Watch Clock Sewing Repair Tool Kit for Watchmakerhttps://a.aliexpress.com/_d8AIMfg
  14. I just watched this. What a cool paint pen. Where can I get one?
