For one of his mechanical engineering school projects, [Ben Murton] decided to design and build a clock from scratch — and while it may look like it was laser cut… He cut it out all by hand.
It’s a cross between the mechanical workings of an old Grandfather clock and a Skeleton clock — the goal was to have all movements visible to see how the clock operates. He designed it using Autodesk Inventor, and has provided the files online for anyone to use — He notes it would be especially easy to make if you have a laser cutter or CNC router!
Anyway, the clock is made out of 3mm thick acrylic, 5mm brass shafts, nylon string, some heavy weights (lead), and some nuts and screws. After printing out his CAD templates, [Ben] carefully used a scroll saw to cut out every gear and linkage — We’re impressed.
Perhaps the most impressive part of this is that he opted for a gravity driven clock instead of just throwing a stepper and microcontroller on the back — it’s nice to see purely mechanical projects are still being done!
