I inherited an old grandfather clock from my grandparents, and I've been trying to get it to work properly for about a week now. I can get it ticking, and the hands move, and the chime works and everything, but I keep noticing that the time keeps falling behind, no matter how much I adjust the pendulum. When I rotate the minute hand around the clock to set the time, there are "weak spots" where it can't really hold itself up. It sometimes falls forward about 10 minutes, or backwards about 10 minutes depending on which side of the clock that the hand is on. The hour hand and minute hand are snug on the spindles (minute hand has a square hole, and it fits snuggly onto the square spindle) but it just seems like the minute hand is getting "floppy" in a 10-15 minute zone that moves around the clock. When that zone happens to be around the 3 or 9 area, the minute hand sometimes falls downward. I'm new to clocks, and don't know much about this clock at all. I just know it's old and it belonged to my grandmother's family. Pictures are attached. Please let me know what to look for or what I could try to fix the issue before calling in a professional. I was able to remove the top cabinet and clock face, but I don't know where to go from here. But I do know that the hand is not loose on the spindle. The whole minute spindle gets loose/weak in spots. The hour spindle isnt having the same issue. Thanks for your help and patience!
