A woman was given a new Howard Miller grandfather clock for her retirement. Some years later the lyre pendulum was coming apart. It issue was that the rating nut was the wrong size and was bigger than the threads. So, someone put tissue as a filler to hold it on - and not sure when this happened. I tried a sample of rating nuts to get the right size, but no luck. The diameter of the thread rod is .125 inches. I tried a 6-32 nut and it is close, but only goes on a few turns and no more. M2.5 and M3 were too small. What else could I try? What would be my options and my best option? 1. Find a new pendulum ($100 more or less). 2. Find a nut at the hardware store that is correct size and place it below the original rating nut. 3. Find the correct size rating nut (looked at the suppliers, but didn't see any good possibilities). 4. Purchase a new center rod with rating nut already attached (I did find one of these with correct length ($12) at one supplier).
