I just finished a Wurthner with Plate 1587, which for the last two days has been functioning beautifully, but I have a few questions about some of the tiny parts that confused me. The small parts were;
1. two tension washers were on the center arbor, both football shaped and stuck together - I knew what these were for, but had never seen two before
2. no idea where a small brass bushing with no oil sink came from
Here is the problems I had with the clock on reassembly;
1. screw holding minute wheel did not have a large enough head to keep the hour wheel from sometimes pulling off if removing hour hand
2. gradual binding of the minute wheel within the hour - appeared to be binding on the tension washer point
3. could not get good tension on the minute hand - hand nut would bottom out
This is what I did;
1. used brass bushing which fit on the minute wheel screw to raise minute wheel slightly which did clear the binding
2. used one tension washer on the center arbor, and the other between the hand nut and the minute hand - hand now has proper tension when moving the hand
3. did nothing about the minute wheel screw, since the hour wheel would only sometimes pull off if you were taking off the hour hand. I couldn't add a washer to the screw, because the shoulder length wasn't long enough
Any suggestions about whether I should correct what I did would be appreciated.
