Really big clock

[kockie-nl]

In a month we have a musical “Ciske de Rat” and the director wants a really big… clock, so I went ino Fusion and designed a clock that resembles the clock of Amsterdam Central station.

The outside diameter is 3.15 meter, my calculator tells me thats 10ft 4 Inches in ancient units, so a one part clock is not possible.

So i made cut the circle in 8 to make parts, 13 out of a sheet of MDF, i need 16 to make a double ring

Not my own workplace BTW, but from the musical association I’m one of the set builders.

Remnants of some milling with my lowrider3

some Roman numerals

The electronics on a breadboard (wonder if it ever comes of the breadboard…)

I made the program with help from chatgpt, it still cost me a couple of long evenings…. I wanted to be able to use NTP, manual time, Streaming acn and DMX, but for now ditched the latter two.

Here the clock mechanics, printing just now:

Two nema17 steppers with wormgear and gear

Still work in progress, hopefully ready at the beginning of next month

Second picture is a clock ring. Is it going to be a big, black clock?

I have a 1.2 m clock built ~12 yrs ago… before i had a cnc and it has hardware store house numbers and the mechanism was and is still the most difficult thing to keep going.

Yours is a very cool clock. I’m very interested in the mechanism.

In 2018 I also build a 1.2 meter clock. It was hand operated from the back. It was used in “the Christmas Carol. Stil hanging in the decor shed.

The angle between midline of the clock and the letters is intentionally, so i can take the clock apart easilly. Otherwise the letters would cross the seams when taken apart for transportation.
