    ETA 2892A2 Amplitude

    Mainspring was only light touch. Thanks for everyone’s help and encouragement; I got the amp up to near on 300 with 0.0 BE and +1 to +6 spd according to my TG. I’m very happy with that so it’s been cased and final test before return to its owner. Sent from my iPhone using Tapatalk

    Pallets re-cleaned and 9415 re-applied. Is this the correct amount? Endstone re-cleaned and 9010 re-applied. No pics of that though. Amp now sitting around 260/265. Getting better. Sent from my iPhone using Tapatalk

    Elma Elite restored

    Another vote for a walkthrough please! Sent from my iPad using Tapatalk
  5. I knew you wouldn’t let me down, haha! And although I *was* joking, yes please to the video. Didn’t know they could be replaced so will be interesting to me at least. Sent from my iPad using Tapatalk
  6. What a fantastic initiative. Good luck to the students and the tutors. Sent from my iPhone using Tapatalk

    Balance took 1m 16s to come to a complete rest. There is a very slight backlash, and I do mean very slight, on the escape. More often than not though it just halts. Can you tell anything about the jewels from the pics above? Do they look about right? Sent from my iPhone using Tapatalk
  8. I feel all your pain, I've had trouble with these and I found out the hard way about checking for the hook on second hand winders. I'm expecting to see a tutorial pop up from @jdrichard on how to knock one together soon (and although I'm joking I wouldn't be too surprised, there doesn't seem to be a lot that man can't manufacture!)

    Can you explain what you mean by excite the balance please? Do you mean to use my blower to get it moving or maybe to turn it manually to a certain degree? Sent from my iPad using Tapatalk

    So here are some photos. It’s amazing how much crap you see at 40+ I used my microscope at 40x and then used my phone to take the pics at between x1 and x8 so there are some close ups. Quality isn’t as good as through my stereo scope of course and forgive the reflection of the ring light. Oh, and I’ve not disassembled to take close ups of the pivots tonight as it’s already after 11pm here and I have to clear all my kit up yet! Oh for a dedicated workspace... Cap jewel hairspring side Cap jewel dial side Pallets, one from each side what is that blob after it’s been run from full wind to nothing? That can’t be good, which means maybe we’ve found something! Some other jewel holes That should be enough to give an idea. I’m totally up for any criticism as I need to know what to do better. I simply must be able to be better at this.

    MS not removed from barrel. Just inspected and a little bit of barrel grease (8201) applied and a couple of small drops of HP1300 placed on top of spring. Sent from my iPhone using Tapatalk

    2892-2 Movement stops completely after hacking

    I’ve just looked at the tech guide (I’m working on one of these myself at the moment so had it to hand - and I’m assuming that a 2892-2 is the same as 2892A2) and I think you are right, looking at the guide I ‘think’ it should be where I have circled in red... I stand to be corrected though. Sent from my iPad using Tapatalk

    Yes, I’m pegging the jewels and cleaning the hole jewels. However, maybe I am not doing it well enough. I’ll up my mag to x40 and try and take and post some pics to see what you guys think. As I think I stated earlier, my suspicion is that what I think I’m getting clean properly, I’m not. I’d like to crack this though as gaining amplitude is something I need to perfect to satisfy my need to become a better watchmaker. Sent from my iPad using Tapatalk

    You are right, I didn’t, so this is what was used: 9010; 1300; 9415; and a dab of 8201 on the barrel floor and cap. All from Moebius and all reasonably new. The parts were US cleaned (small cheap domestic one I have) in small glass jars in a 40/60 mix of lighter fluid and white spirit and then rinsed in IPA before drying. The pallet was cleaned manually with pegwood and Rodico. The balance complete was dipped and very lightly agitated in Perc (perchloroethylene) and suspended and left to air dry. The cap jewels and holders we’re removed and agitated in Perc before further manual cleaning and oiling with 9010 and reinstalling. Sent from my iPad using Tapatalk

    I let the movement run from a full wind straight after reassembly (which was showing at around 240amp and about +1spd) for around 24 hours and measured the following: My thoughts on next steps are: 1. Disassemble and re-clean pivots and holes 2. Give the balance another dip in Perk 3. Do the oiling from scratch 4. Re-clean and reapply 9415 to the pallets Anything I’m missing? Could this be down to the MS which I did nothing with apart from opening the cap and applying a spot of fresh grease to the barrel floor and lid and a drop of oil over the coils. I’m now wondering if that was a poor decision. TIA Pip Sent from my iPhone using Tapatalk
