    Whenever I service a watch, I always remove the jewelry from the balance wheel, the roller and hairspring (HS)
    A tricky job at the best of times. Fortunately I’m like an old ad the went like this….,

    Wanted: person with long thin fingers for taking things out of long thin jars 😆
    But if a person has large hands, holding the balance is difficult and removing the HS is even more difficulter 😆

    I’ve tried the few methods available,and there aren’t many, in removing the HS but my preferred method is a tiny 0.35mm screwdriver that I made up especially for that purpose, in fact, that tiny screwdriver is my staple for many different little tasks.
    Yesterday I decided to mess around and make a HS removal tool that I saw on a video a long time ago, which was my reason for using the screwdriver initially..
    It consisted of two small pieces of brass round stock that I fashioned into pry bars.
    This was brought about by a Waltham that had the tightest HS ever, and I struggled with it, almost disastrously, until eventually getting the thing off.

    So I tried my bars on a 16s HS afterwards and VIOLA off the spring came as slick as **** 😆
    It was a good test because it was a smaller HS and it was tight..

    What do you guys use for this fragile job?

    I also made a tool like Bob shows in his video’s. It works pretty well for me. Be interested in seeing your tool.

    All:

    I too made one like Bob’s. But I also made three as described in the Chicago School of Watchmaking. They are made from old mainsprings of various thicknesses and widths. They work pretty well – a drop of oil and a twist and off comes the hairspring. Adjustments are easy too. I’ll admit that they aren’t very attractive. ;)

    Later,
    Tom

    Guys I didn’t forget about this but I’m away until Thursday and the only image I have is a HUGE one on my pod, which needs to be edited down a piece or two 😮

    I’m sorry to admit but I can’t remember the type our Bob shows in the video 😳 I always was a poor student 😆
    Can someone post an image please..

    I don’t have a pic..but I’m spoiled in that I have my Dad’s set of hairspring tools…the kind that came on small clear plexi rods. The removal tool looks a bit like what Tom fashioned.
    I take the balance,.set it into a hole in my bench block that accommodates the roller, and then whilst ( notice that I’m working on my queen’s english ), holding it with my fingers near the rim,..I gently insert the tool and twist / lift until it releases.
    The key here is patience, and I like Tom’s idea of adding a bit of oil…..

    Chris..nice looking levers you’ve crafted ….

    Randy, I did notice your very correct usage of “whilst” and I am impressed :D Have you been slipping over to Van 😆

    Chris:

    That’s a great idea of using brass you won’t scratch anything that way.

    Later Tater,
    Tom

    That’s where I’ve spent the past week visiting the fam, except my queens has degraded into something that sounds like
    EyeYAHH Aw’right 😆 no idea where that came from ;)

    I thought with you being next to Van , or little England as we used to call it, you might have been influenced 😆
    It was always funny to see lines of people going into Vancouver from the US side while we were going to buy cheap products from your side. Communal border hopping 😆
