  1. The first of a few vids planned on the subject.

  2. Thanks RicardoG for your concern but no problems. I mentioned above that I got the plate parallel within half a thou (0.01mm). I kept measuring it every so often for flatness and parallelism of the top and bottom surfaces around the plate. It came out quite good - could not really ask for more. Still I will keep looking for a replacement (or spare).

  3. Hi Garry, I like the look of that, what a pity about the pallet jewel. As a matter of interest, whet did you clean it with?

  5. Good(?) news! There is the question mark because it will show in usage but after 3h 40min of grinding by hand I've arrived at very satisfactory outcome. 1. I used very old, kind of, microscope/eyepiece 30X mag. and LED torch to find the thickness of the micro holes - roughly 1mm - 1.5mm 2. I found diamond knife sharpening block (really cheap in our local Aldi store) with four different grits: 200, 300, 400 and 600. 3. Gradually under running water I honed the plate 0.3mm down. Measured with micrometer every so often it came out flat within 0.01mm. It needed quite a pressure to grind it - hard, hard surface. Initial hardness testing (using sharpened file) indicates that the surface does not scratch at all but it will show in the usage. The other problem is the remaining thickness. One issue is I lost the little dimple that I have no idea what it is for. I think I will try to grind it with finer grit, like 1200. At the moment I am happy with the job - although my elbows need rest :-). The important bit was to keep checking the thickness around the plate. The power of several minds! Thank you all. :-)

  6. Micky. If the hand is loose then I mount it in a pin vice and tighten it little by little until the job is done. I have a very high success rate this way. Sent from my iPhone using Tapatalk

  8. Welcome - but you do realise, don't you, that all new members have to contribute a watch to a Senior Member on joining the Forum? In this case, I'm in sore need of a Jaeger-LeCoultre... :D

  9. Here is a video I really enjoyed recently. I am so tempted to get one of those winders even though I rarely work on clocks these days.
