Hand Making a Verge Watch Hairspring Pt.1

I do these videos for free, un-monetised. YouTube now put ads on any video to give themselves revenue, whether the content creator wants it or not. We don’t get anything. Sorry for the interruption. I make a wooden jig and use it to reduce a piece of music wire to match the dimensions of a hairspring from a late 1700’s Verge Pocket Watch. I used the finest music wire (sometimes known as Piano wire) made by K&S Metals. I buy it from model aeroplane stores and it is quite cheap. A link to Richard Watkins PDF books
