Antique Rusty Micrometer - Precise Restoration

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 choose 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.
