Oleg's Magical Mystery Box

Remember the Mystery Box Mechanical Gizmo?  If not, link here:  https://www.youtube.com/watch?v=lxyQ3PFbK9Y

Our wonderful builder friend Oleg in Russia built it and filmed his adorable daughter's reaction to it!


She was not impressed, but isn't she adorable??  Thanks, Oleg, for giving us a chuckle.  What a cutie.


Weird Gears and Zinnia Kinetic Sculptures

Brad Petrovic's Zinnia Kinetic Sculpture

Two original interpretations of my kinetic sculpture plans:  First, Brad Petrovic's beautiful Zinnia sculpture--below, you can see it in action in a YouTube video.

The next is an interpretation of my Weird Gears plans:

I'm always surprised and delighted by creative uses for my plans!  Thanks for sending these in.


Ken Duffy's Magical Collection of Ticking and Movement

Toucan, Harmonic Oscillator, Flying Pendulum by Ken Duffy
Talented woodworker Ken Duffy sent us these wonderful pictures of his home filled with Clayton Boyer clock and kinetic sculpture designs built by Ken.

Balance, Zinnia, Bird of Paradise, and Simplicity by Ken Duffy
All the ticking and motion must be wonderful!
Another Simplicity, and another shot of Balance.
I am also happy to report that Ken is currently working on yet another Boyer design, the Deco Clock.  Thanks for being such a great customer, Ken, and thank you so much for sharing your pictures.  We can't wait to see your Deco when it's completed.


"Ghost of Time," An Acrylic Simplicity by John Owles

Ghost of Time by John Owles, a Simplicity Variant

Acrylic looks amazing when used in these kinetic sculptures, however I usually warn against using acrylic for the wheels and pinions of these wonderful mechanisms because acrylic-on-acrylic contact has very high internal friction - an increased friction that is much higher than wood-on-wood.

Ghost of Time by John Owles, a Simplicity Variant

However, despite the issues with acrylic, John is an acrylic sculptor and wanted to create his beautiful Simplicity completely in acrylic, so to avoid the internal friction intrinsic to acrylic contact, we worked together to create a Simplicity design that has no acrylic-on-acrylic contact.  If you are interested in creating in acrylic, contact me before your build and we can work on the design modifications that will allow you to create a beautiful, functional sculpture.

John made a YouTube video of his "Ghost of Time Simplicity," below.

Chuck Cantieny's 1/3 Scale Genesis Clock

Dear Readers, here is a video of an amazing Genesis build that I think will entice your imagination. How small can a clock be before it becomes a watch?  Chuck has pushed that question to the limit. Take a look, and prepare to be amazed.

Hi Dr. Boyer,

I had ordered you plans for the Genesis clock almost a year ago.  I finally got around to building it.  I thought it worked out very well.  I have attached a video that shows the results of the build.  I think it is a "little" different than most of the versions I have seen.  I will also include a couple of higher resolution photos.  I am going to try to post the video to You Tube,  that will be a first for me.

Just so you know - I don't buy a lot plans.  I am a long time cad guy and currently a cad instructor so I create most of my own plans.  I find your designs amazing.  Thank you for sharing with us.



A Great Question About Center Holes

A clock builder asks:  "Should I be worried about this being too far off?  When I sand this wheel on a mandrel some of the printed lines for the teeth will fully disappear while others will be just showing.  Thanks."
Center Wheel Hole Off--Problem?

Clayton answers:  Euuuuuuw!  I really hate seeing that.  Did someone just kick me in the stomach?

These mechanisms are extremely forgiving of front to back wobble, as in the ply being warped.  As shown in the picture below, as long as the wheel can stay on the pinion the mechanism can be made to work.

But these mechanisms are extremely UNforgiving of up and down wobble, as in having the center hole for the arbor off center.  Those PD lines really must align perfectly all the way around the wheel.  As much as that hole is off from center one way, it is off double that amount on the other side.

The center hole is probably THE most important hole in the entire clockmaking project.  If, for example, a frame hole is off a bit, the PD's are still aligned perfectly all around.  The teeth are simply just a bit further apart ~  But if the center hole of the wheel is off, you've created a cam.  On the down side the cam will have too much clearance, and on the up side the cam will jam.

Now, that being said, yes, you can, with a lot of work, probably save that wheel.  You'll need to depth it, and in the process, you'll need to deepen the dedendums of both the wheel and pinion, and the addendums will already have been shortened by the process of spinning the wheel and sanding it perfectly round at the sander.  You may also need to remove some of the BACK side of each tooth in the area of the out of center hole of the wheel has caused the PD's cross each other.  That is because the tooth gets wider at its bottom.  The back side of the tooth is the non-contact side.  You'll need to look at your mechanism and see which way the wheel is traveling and determine which side is the non-contact side, and remove some "meat" from that side.  (as I mention in my book, the back of each tooth can be nearly ANY shape because clock gears only turn in one direction.)  This will, of course, show as asymmetry in the overall wheel's appearance unless ALL of the backs of the teeth are treated the same way.

The center hole in the picture you sent looks terribly off, but if in reality it is not really off by that much, give the wheel a try, and spend some time practicing your "depthing" technique.  You may even eventually qualify for your honorary Doctor Of Dentistry degree from all the additional tooth work.


Aloha, Clayton
