Should the 3 weights in a grandfather clock fall evenly over their 8 days? If they do not, how do I regulate an equal fall for these weights in this customer's clock? The clock owner is very insistent on this. There was no identifier on the movement showing the clock's brand. The mainspring arbors have stops on them and they're set accurately. The movement has been completely overhauled and, apart from this issue of uneven weight falling, the repaired clock is perfect.
