In this video i'm restoring an antique swiss watchmaker micrometer.
I bought this micrometer on eBay for $25. When I was scrolling through the antique section of eBay and first saw this micrometer I wanted to restore it right away. I really like the unique look of those watchmaker micrometers. As a professional CNC-mechanic I'm very familiar with those measurement devices and I'm using them on a daily basis. The measurement range of this micrometer is from 0-25mm and you can measure exactly on 0.005mm. The micrometer was in a very bad condition, it was very rusty and it was kind of stuck. It was once re-painted to yellow, the original colour was black. That's why I decided to paint it black again. In the front of the micrometer there was a plate with the name and the location of the previous owner mounted with two rivets. The plate was in very bad condition and as I'm the new owner of it, I decided to make a new plate with my name and my location. I choosed to create the plate with etching using ferric-chloride. I've never done that before, but the result came out very nice. Unfortunately I wasn't able to remove all the spots from the rust on the two parts with the scale on it, if I would sand it more I would lose the engravings. I'm still very happy how this restoration turned out.
I hope you like my work and the video.
