felsa 4007 barrel set up

[gary17]

Hey guys

has anyone done a mainspring change in one of these.  As i say above it is a felsa 4007.

The first 3 pics show the top of the barrel, See the hook in pic 2. That then goes over the piece sticking up in pic 4. But i am finding it virtualy impossible to hand wind the mainspring into the barrel pic 4 the sticky up thing gets in the way. The piece in pics 5 and 6 ( it acts sort of like a arbour) it has no hooks and no use except to center it when it goes into the watch. The arbour does not turn. The part of the barrel with the hook. ( see pic 1,2,3) turns via a wheel attached directly to the  intermediate wheel.

Any way back to my question. Has anyone come across this set up before and if yes howq do i go about getting the spring back into the barrel.

cheers

unhelpful answer it kinda looks like a weird version of a waltham pocketwatch mainspring barrel. Except that barrel does not have the center part that you having a problem with. If you can't hand wind it in then you're going to have to find a mainspring winder.  or a new mainspring and just push it out of the ring.

Wind this mainspring inside a washer of the same or a bit smaller ID than that of the barrel, rinse!  ready to push in as you would new replacements MS's in.

Good luck.
