Just out of interest I thought i would try a ball race in the drive weight pulley because it is the most heavily loaded bearing is the clock. i found a 625zz in the odd bearing box, and made a new pulley to fit, the result was the clock gained 3/4 of an hour a day !! I have regulated the clock and will make a new drawing for the constructors when i am satisfied all is OK .
