Water Powered Pendulum Clock

My own unique design Pendulum Driven Clock which is driven by the weight of the water landing in the 'cross' tube of the pendulum assembly which is divided by a baffle. As the pendulum swings the water is forced to flow into one side then the other... the resulting movement then powers the clock by means of the escapement (ratchet) wheel.
All white parts are machined from acetal, the gears are hand cut on my band saw and 'broached' where needed with pillar drill (drill press).
All shiny parts are stainless steel, welded with my 'RTECH 200' tig.
The Clock 'ticks' at 46 beats per minute and therefore the escapement wheel has 46 teeth... from there on it is simple to gear the minutes and hours. Apart from the obvious water power (small pond pump in base), the other unique thing is the drive from the escapement (Not a true escapement as it only drives the clock and isn't regulating the drive from the pendulum in any way) to the minute (60 tooth) wheel is by effectively a one tooth gear, having a single peg which only engages once per revolution and does away with one complete 60 to 1 gear train.
Fine adjustment is via a bob weight at the bottom of the pendulum and works opposite to convention, i.e. up is slower and down is faster (due to the amount of time the water has to escape the tube)
This is my first attempt at building a clock and took me 10 days straight!

Wow! I cant believe you made those gears with just a band saw and drill press. Please please please make a video showing how you do it - only then will I believe.

@johnpanter When I have a bit of spare time I will make video...It is not difficult, you just have to have a good eye and not slip!

awesome

amazing work.

Very Very Cool!!!!

A wonderful innovative mechanical work.

astounding! okay, it's probably not the most accurate timepiece (there're bound to be minute variations in the impulse transfer, and the amplitude of the pendulum excedes

isochronal limitation), but i'm sure it holds up well enough.r egardless, the concept is brilliant, and the excecution, nothing short of art. djohnson16mindspring has the right idea: this piece is ideally suited for (but certainy not limited to) an outdoor installation.

bloody hell, that's probably the coolest clock I've ever seen in my entire live

This is fantastic, I love the simplicity beauty of it. And the water drive, I've been wracking my brain for something to do as a "water feature" in my yard, I might just have to steal your pendulum concept. I hope that's OK.

Love the simplicity. The stainless and acetal are an excellent complement to the mechanical design.
