Antique Clocks/Antique schoolhouse clock losing time


Than you for taking my question.  My antique regulator schoolhouse clock progressively over days. It has lost 6-7 minutes per day.  At the end of the pendulum there jus a small circular washer like thing that will turn. Is this where I adjust the time to make it  faster or slower. Thanh you for your help.

Yes, turning the nut clockwise will generally raise the pendulum which speeds the clock up. Counter clockwise will slow it down. When turning it counter clockwise be certain the pendulum bob actually lowers as sometime friction will read downward movement.

I can not think of any questions I cannot answer in regard to repairing antique clocks or radios. However, I am sure there are a few I have not heard and may not be able to answer. If I cannot, I will say so. I have been repairing them since I was a young child.


My experience includes repairing CooKoo clocks, Westminsters, BimBam, almost all antique clocks. I do a bit of repair on battery clocks where the value is sufficient to warrant working on them. I also repair antique (tube type) radios - all makes.
