I was in the process of replacing some broken trunions on two lantern pinions in my very old Jungmans bracket clock and thought I had better check the condition of the mainspring. I am glad that I did because the arbor hook had been warn (or broken) away so that only a tiny pimple of metal was left holding the spring in place. Anyway, after finding your excellent video I decided to have a go at repairing it myself and I am pleased to say it all worked a treat. Many thanks for a really useful video..
Mainspring-driven clocks often have mainsprings in barrels. The outer end of the mainspring catches on a hook inside the barrel and the inner coil of the mainspring catches on a hook on the winding arbor. If one or the other of this hooks becomes damaged, the clock can't be wound because the mainspring won't catch. The ClockClass DVD discusses the repair of both of these hooks.

I'm pleased to hear you found the video useful!
The best one idea👏👏👏👏
عمل رائع جدا..شكرا..
I use a large headed nail.
You did not create a hook with the head of the screw. It must be filed towards the screw shaft to properly catch the Main Spring.
Gostei muito, só que tem um problema não entendo o que está falando . Só brasileiro

it is much more productive to use a screw with a hat under 45 degrees
