Recently I posted about the two weight Willmann movement that I bought. I did not come with weights, pulleys, case or pendulum.

I've cleaned it, polished the pivots and bushed most of the time train and some of the strike.

Estimated I might need a 21" pendulum rod (based on my faulty calculation). Added 3 ½# of weights to the time side and gave the 2# bob a nudge. Ran steady, but the second hand (on the escape arbor) was making a rotation about every 45 seconds. Need more pendulum rod! I finally wised up and clipped my beat counter to the unit looking for 3600 BPH. Ended up adding another 10 inches!! From hook to center mass of the bob is 39 ½", to the bottom of the bob is 41 ¼".

Please ignore the blue tape I used to add temporary weights and shaft length.

Thanks everyone!

**Are****they normally this long??**Second hand is sweeping at 00:59:72, which when the new pendulum rod is made with screw regulator on the bottom I think I can get even better.Thanks everyone!
