Just an update. 

I used a diamond disk to free the washers from the mainspring arbor and replaced the worn off paper washer.


I had some paper washers on hand but the centre hole was of the wrong diameter. I spent about an hour reaming the hole to the correct diameter and sanding it down to a thickness of 0.6mm.

I then reassembled the stack of washers and spot welded it with my micro tig welder. 


Reassembling all the wheels, levers and springs and screwing down the plates was a nightmare. The springs were bulging out and pushing against everything. 


But finally everything is back together and working properly.
