Does your parts list actually have the description as mine just shows the parts. Is 1520 the gear that sits in the auto bridge to couple to the barrel. You could try letting the power down and then remove the idler gear between the 2 barrels and see how it winds then. I presume you're doing all this at the moment without the auto bridge in place. -

I love my brass tweezers and use them for 90% of my work. I like that brass is soft and does not scratch parts and it seems to grip parts better than stainless steel. And brass is also non-magnetic, which really helps when working on quartz movements. However, brass is a little too weak for jobs like pulling back yoke springs. So I thought of upgrading to bronze. But I can't seem to find curved bronze tweezers. And Cousins price for a pair of Bergeon straight bronze tweezers is around £45. A couple of months back I had the idea of swapping out the carbon fibre tips of my tweezers and putting in bronze tips. And that is what I did. I got a piece of 2.0mm bronze sheet from AliExpress and cut out 2 curved tips and replaced the carbon fibre tips. I'll probably thin down the tip further gradually to a point where it still has strength to draw back thick yoke springs. -
Ah, well that's a relief, though the parts document does list a 1520 which is a coupling clutch. This threw me for a while (it's a quiet day in the office) until I realised I couldn't see a listing for the reverser wheels. So, we're back to the mainspring should slip in the barrel. It can really only be one of three things (that I'm aware of) mainspring 'coned' and pressing slightly on the lid the kink, close to the end of the spring, which puts a sort of a self lock grip on the spring and may not allow the spring to release enough there to allow slipping quantity of lubrication, either not enough, or too little Two of those require new mainsprings, which aren't readily available, though I may post a query about alternative mainspring sizes. The third, will more grease or less be required? The word breaking in breaking grease suggests more means more breaking? -
The idler gear I'm referring too is the one between the 2 barrel wheels. These movements just rely on the spring slipping to prevent over winding.

Not sure how useful this might be, but a while back I bought some bamboo tweezers (multipack with a ridiculous amount of them in) and have been using them in place of pegwood. Seems to be working just fine
