At Cambria Tech Ltd., our day-to-day work usually centres around helping organisations refine their business processes and navigate technology deployments. But every so often, a request comes along that sits outside our usual remit—yet sparks our curiosity enough that we simply can’t resist taking a closer look. We love a good challenge, especially when it lets us put our engineering instincts to work in unexpected ways.
That’s exactly what happened when we were introduced to a local group of volunteers responsible for a turret clock in a church tower. Their Victorian clock had begun running fast, and although it was under contract with a respected specialist firm, the volunteers weren’t in a position to cover the call-out costs for what might have been a straightforward fix. They asked if we could at least take a look.
We were very open from the start: we’re not clockmakers. But a piece of Victorian engineering paired with a modern control system? That was enough to pique our interest.
After climbing the tower and examining the setup, we carried out our own research into turret clocks—an unexpectedly fascinating rabbit hole—alongside studying manuals for the modern device installed in the clock chamber. This device uses a movable electromagnet to momentarily pause the pendulum and correct the clock’s timing each hour. A beautifully clever solution for older clocks.
It didn’t take long for the picture to come together. The clock itself was running exactly as it should—but it had been intentionally set a little fast so that the control system could make its hourly correction. Unfortunately, the small plastic plate on the pendulum (the piece the magnet attaches to) had broken. Without it, the mechanism had nudged the pendulum slightly out of alignment, causing the problem the volunteers had spotted.
When we began investigating replacement parts, we made an amusing discovery: the piece wasn’t some obscure, specialised component. It was identical to a widely available automatic fire-door retainer costing about £7.
So we sourced several replacements, returned to the site, fitted a new plate, and left spare parts—and even a small toolkit—inside the clock chamber so the volunteers wouldn’t be caught out again between maintenance visits. After realigning the pendulum and checking the magnet’s operation, the clock settled back into proper timekeeping, and it’s been running happily ever since.
For the volunteers, the solution cost significantly less than a standard call-out. For us, it was a rewarding opportunity to apply engineering thinking from one field to a completely different one.
This little adventure up a church tower is a great reminder of what we value at Cambria Tech: adaptability, curiosity, and a willingness to use our broad technical experience wherever it can make a difference—even in the most unexpected places.
