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.
In this, the conclusion of the Hairspring series, I demonstrate how to use the curling tweezers I made in "Makin' a Tool. Episode 1" ,( https://www.youtube.com/watch?v=0h--nJZPVD4) , and then how to finish truing the hairspring, ready for use.
