Someone got in touch regarding a family heirloom clock that wasn’t running. The Bentima clock itself was in good overall condition and considering its age, had been in the same family for a couple of generations or so. The owner really missed the clock ticking and chimes on the hour.
Access to the clock’s mechanism is pretty straightforward on this type of clock as there’s a simple wooden door on the back with a catch. Opening up that door reveals a weighted pendulum with escapement above. It was clear that someone, at some point, had replaced the pendulum spring and that all that was probably required was a minor adjustment to make the ‘tick match the tock’, or in other words, get the clock back ‘in beat’…tick-tock-tick-tock-tick-tock… evenly spread.
On this mechanism, all that was needed was a level surface and a small flat-bladed screwdriver to slightly move the pendulum pivot point. Once running, a small adjustment to slow-down the running was needed (time was too fast), but this was easily adjusted using the knurled screw on the pendulum. I recommended that if a flat level surface at home couldn’t be found, 1 penny pieces could be used under the clock’s feet to restore balance. A nice little repair.
Cost of a clock like this: Check eBay. Cost of repair; my time.
