Using any main spring winder is a learning curve. After a few more springs you will be a pro. If you get frustrated walk away and take a breather.

Instead of being a pro, I've got a problem.
I've got a spring which I can't wind in the winder because it has become unhooked from the rivet in the barrel. I've got it hooked onto the arbor hook, so the problem has to be the other end of the spring at the barrel rivet - which I can't see of course because the spring is pressed up against the barrel.
I am assuming that the only way to deal with this is to ease the spring out of the barrel by hand. Thought I should check before I go down that potentially explosive route.

Can you try to re attach it, maybe move the loop to the rivet and push it up with a screwdriver.
Other wise yes remove by hand, use a towel in your lap to control spring comes out controlled.

Looking at the Horolovar Guide for something else, I noticed a paragraph on how to solve this problem (P61). As the saying goes, 'If all else fails then read the instructions'. Basically, you turn the spring round in the barrel with a key, and it should hook onto the rivet - and it did. One turn, just as the book says.

Irwin sometimes they will and sometimes not. Maybe you had a lucky day.

I just came across something 'interesting'.
I'm working on this Badische and when I went to deal with the spring I realised that it's configured so that the barrel teeth are against the back plate and not the front plate as in the JUF and GB clocks. The significance is that these barrels cannot be handled in the winder because they are the 'wrong' way round.

The Badische,

The rebuild and this is the backplate,
