Getting a stubborn hand to fit correctly on an hour wheel

Approximately two years ago, I stumbled upon a weight-driven banjo clock listed on Facebook Marketplace. Before finalizing the purchase, I engaged in a conversation with the seller, who appeared to have limited knowledge about the clock’s value. The clock was among several items that the seller’s family was parting with, and it was evident that they didn’t have any sentimental attachment to it, despite it being in their possession for several decades.

To my surprise, the clock was remarkably intact, with only minor veneer issues. Apart from routine servicing of the movement, the clock required repairing the small sections of veneer and mounting it securely on the wall.

I only needed to replace one bushing in the movement, and that resolved the only wear issue.

However, the hands of the clock posed some challenges on a couple of occasions. Firstly, the minute hand became loose and wouldn’t advance properly. Upon investigation, I discovered that the hand was not securely attached to the minute wheel. I resolved this by using a slightly larger taper pin to tighten it.

Later on, the hour hand started causing problems as well. It became loose and wouldn’t advance correctly. The minute hand, the hour hand doesn’t have a collar as you would find on a conventional mass-produced American clock and relies on friction to fit onto the top section of the hour pipe. There isn’t much room to work within this area, and it’s either too tight or too loose. Tightening the hour hand requires carefully punching the inside of the hole to make it smaller. Once again, due to the limited space available, this was a challenging task.

The hands stayed in place and now to test the movement for any issues.

Repairing a loose hour hand on a weight-driven banjo

The hour hand is loose on my unmarked circa 1840s banjo clock. It is an unusual problem and I can’t say I have ever come across an issue like this in my years of clock repair. It is supposed to friction fit on the hour pipe but the hand is definitely quite loose.

I have attributed this fine precision-made weight-driven banjo timepiece to John Sawin or one of his apprentices or associates. John Sawin, who apprenticed under Simon Willard, made clocks in the Boston area in the early 1800s and it appears that this clock was made in or around 1840.

It is not the usual ornate clock with reverse-painted tablets, gilt features, and an American eagle finial that one would envision as a classic banjo clock. This mahogany-cased clock is simple with timeless lines.

Back to the hour hand. I posted the issue on an online clock forum site and the consensus seems to be that I must stake the hour hand in several places on the inside so that it would fit tightly on the hour pipe.

The hour hand is on the right

On most American clocks the hour hand has a collet and the hour hand/collect friction fits onto the hour pipe. No so on early banjo clocks.

The staking went well, the hour hand fits snuggly and I am pleased.
