I have a Barnes and Bartholomew wooden works 30 hour clock. Last fall it was repaired by a member of NAWCC that lives near me. It ran well and kept good time. Then it stopped. About a month later I had to move the clock and as it sat on my dining room table it started ticking! I put it back in place and it ran great for about 2 months. Last night I noticed it wasn't running. I know I have not given you much to go on but what could be causing this? Temperature or humidity changes? Anything simple I should try?
