Hand Making a Verge Watch Hairspring Pt. 1

I do these videos for free, unmonetised. YouTube now put ads on any video to give themselves revenue, whether the content creator wants it or not. We dont 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 1700s 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
