Aw come on Andy, it was just a comparison between spending 30 quid and tackling a tricky piece of work. You appeared to be volunteering, i volunteer for stuff all the time it gets me into all kinds of trouble. -

It's not really shown here , but the blade flips over, so it faces the other way. The knob and threaded case holder then pushes the caseback seam into the blade. Once the blade starts to penetrate into it, the lever and blade are lifted , which should hopefully pop the back off. A lot of fashion style cases have very tight seams and need a sharp blade to start separating them. Don't buy the cheaper plastic versions of this tool, the posts with the pins through for blade holder break easily if the apply extra force to blade. -
You will still be looking for a balance complete I’m afraid, this is the balance staff, balance wheel and hairspring in one package. Hairspring and the balance wheel are matched in the factory. Whilst we can change a balance staff the hairspring and balance wheel stay together. Tom -
The hairspring end has come adrift from the small terminal barrel. I have tried to remove the taper pin to relocate it, but the task is beyond my skill set, eyes, hands and being in my 70s, probably beyond my life expectancy. It is not too badly mangled on the end. On the ebay offer, that really is a bit on the rich side. I'll keep looking, maybe a good hairspring will turn up with a shot balance staff. As for time spent on knees. I made up one of these from 3M magnetic tape and a piece of wood. It works well for magnetic parts. Other things I have suffered with. I found lubricants so very expensive that I bought some very small syringes and tiny needles. I just decant a drop into my oiling pots when I start a movement and the remainder keeps really well in the syringes. Finally identifying the correct screw for the part led me to make up the board in the final pic. Thanks for the info. Kind regards Chris -
Yes that's the type @watchweasol is referring too but I don't like them as you don't get any feel to what's happening.
