Zybach: a mechanical clock

Zybach is a simple weight driven wooden gear clock. Its circular forms are reminiscent of crop circles, giving the clock its name. It’s named after Frank Zybach, inventor of the center pivot irrigation system, which revolutionized farming in the mid 1900s.

This is a piece that took far longer than expected to complete. I expected that after building more complicated mechanisms like those in my Colibri sculpture, designing components for a clock like Zybach would be quick and easy. I was wrong! Although a majority of the design was trouble-free to create, I went though three completely unique iterations of escapement design before I finally had something that worked well. Creating Zybach turned out to be a humbling experience for me. It reminded me that things are not always as simple as they may appear to be. Even a seemingly simple mechanism can take a surprising amount of effort to get right.

That said, Zybach is finished, fully functional, and if you would like to build one yourself, you can purchase the woodworking plans at my website: www.derekhugger.com

And last but not least, here’s a video of Zybach running: https://youtu.be/QJ_tt9Cdxh4

I love your work but as much as I wanted to buy the plans for Colibri, was totally intimidated by it. I’m thinking Zybach may be a good place for me to start with to work up my courage for your beautiful hummingbird project! Thanks for sharing Derek!
Somehow the name seems so appropriate! I know you named it after Mr. Zybach but it reminded me of xylotomy (which is pronounced with the same “zy” sound), which is defined as:

The microscopic structure of the wood of a plant or group of plants.
The preparation and microscopic study of sections of wood.

Xylo- (Greek) being a preface for wood. I designed a wooden kit-car body some 40 years ago which I called the Xylot. Brings back some great memories…

Derek…I’ve never seen anything like this before in my life. I just viewed the videos of every project on your website and I was completely blown away, especially after watching Colibri. It was humbling.

Nice work . . . Did you include an adjustment to the escapement rocker arm to tune the pallets on the escape wheel?

As an engineer, I love works of art like this and I would love to have the time to build some things like this clock. You did a beautiful job on this project.

Absolutely amazing clock! I definitely couldn’t have one in my house, because I’d just watch it all day, and not get anything done!

Beautiful, amazing! I have made one of your clocks, it was a delight to work with and sculptural conversation piece on the wall.
