if you don't mind, how heavy is the weight and also how long is the pendulum? i'm currently trying to make my own.. have the clock done but just need those last bits of info (or i could tinker around with it for a while.. ). On a side note, when first started mine i tried using a differential connected between the crank, weight and gears to make it so when cranking the clock doesnt stop but it ended up being too much stress on the middle 12t gear in the differential.. still want to work on that
update: ive found my clock runs about 4% fast at just under 5 lbs (2200grams), with a pendulum length of 12 15-hole studless beams, each connected to eachother by 2 black friction pegs with a hole in between (for anyone else who would like to know)
Currently about 14 hours. I could stick a longer string and pulley reduction on it if I was ambitious and easily get it over 24 hours, but it would start to become a pain to wind up with such a long string.
Just takes some tinkering, and a lot of playing with gear reductions. (also, some grease helps!)
Right now it has a different weight on it than in the video, which actually has a pulley. The string runs down from it's spool, around the pulley, and back up to the clock. This lets the weight pull out twice as much string, although a heavier weight is required.
At the moment it keeps time to within about a minute every six hours. Adjusting the speed is easy; just adding or taking away small bricks from the end of the pendulum.
There is a special gear that doesn't attach to the axle, but instead has a spline mount on its face. Try going to bricklink (.com) and searching for "16 tooth gear with clutch".
THAT CHIMING SOUND WAS FROM PINK FLOYD!

how did you build this?

@snes64dsi I don't know the best answer... it's just a result of hours upon hours of tinkering with the greatest toy ever made!

very impressis but, It would run longer if you hadn't drank all of the booze from that jug :)

how long does it go before it needs to be rewound

how did you make the pendulum go for 14 hours?

how accurate is the clock?

What trick did you use to get both hands rotating about the same axis?

Did you make the clock from your own plan?

Yeah, it's my own design. I tried some of the others that I saw online, but this one seems more consistent.
