Really.  There's a lot to learn there for me.

Jim,

I use the sliding compound, which was originally formulated for cabinet drawers.  It has the consistency (as I read in one review) of snot, or if you want to keep things more polite, of warm butter.  I've used it on a couple of cams and found that it disappears into the wood as far as looks but keeps the lubricating qualities.  Not cheap, but good.

An Interesting Korean automata video

 

Good evening...
I ran across this video a couple of days ago.  Before posting this link I've watched it several more times to ensure that I continued to see the value of posting the link.
To me, more than anything else, I am enjoying and appreciating all of the different methods that he uses to create movement.  These pieces are not painted and the videography is very good...so it's easy to see what is going on.  The spoken language is Korean...most of us won't be able to understand the spoken words...but there is still a lot of value.

Thanks Gus, the drawing was worth a thousand words. :)

Hi Mike,

Attached a couple of drawings, one showing an alternative to using gears to rotate, and another way of constructing a follower linked to a cam.

Hi Mario...
Well that is certainly a bit of useful advice.  I've never heard of Slipit.  Looked it up just now and can see that I should have some.  What is your preferred product.  The woodworkers sliding compound looks interesting.
Thanks for the tip.

Glad you like it Jim!

Gus,

The cams worked smoother without the bottom portion attached, as they would occasionally bind. Once removed I found no reason to keep them. (good eye. :) )

It will be driven by a hand crank.

The bevel gears seemed to produce the desired effect, what other type of mechanism could be utilized here? (I'm always interested in learning different ways to do something.)

The gears are from Cranky Crab, but I will be able to cut something similar when my CNC is back online. I enjoy using mixed media, but have more experience in wood working.

Hi Mike,

Very festive scene, just right for this time of the year ! Nice work, and colours. Some observations;
The shot of the cams shows a captive cam arrangement, with a follower top and bottom. These are different in the final photo, were they not successful ? If not, what was the problem with it ?
Will it be driven by a motor ?
The cam arrangement could be simpler by doing the follower as the "capturing" device, so that a single cam per figure is needed. (That is, if you seek simplicity )
Were you particularly wanting to use bevel gears to drive the trees ? 
Are the gears printed, as are the reindeers and sleigh, and do you intend to do as much as possible with future projects using this technology ?

No doubt you are busy with the festivities planning etc, but looking forward to seeing everything move.

Regards,
Gus

Hi Mike...
Thanks for sharing these images.  This automata looks great...very festive.  
Lots of things going on.  I like the little snowmen on their surfboards...I like the candy cane  spinner that is near the crank handle...I like the entire top section.  Your drive section is very neat and tidy and functional (of course). You've done yourself proud  I look forward to seeing your video.
Good job.

I made quite a bit of progress over the last two days.

Front view of the entire automata. Santa and the reindeer move in a wave motion, the trees in the back ground spin in opposite directions and the snowmen below move up and down as well. The bottom of the enclosure isn't attached yet.


Here is a closer look at the mechanics.
 

 View of the mechanics from the back. The smaller gears will be used to drive a music box assembly, which is not in place yet.




Here is the side with the crank, which will be dressed up a bit more.

I still plan on adding a backdrop, but it's about complete. Once everything is in place I'll create a short video.

Comments and suggestions always welcome!

I've won't the gears to run smoothly without lubrication, but use bee's wax wood conditioner or wood butter (Which can also be used on wooden bowls and spoons).

I have ordered several different types of gears from Cranky Crab, made of different materials and have liked them all. If I had to pick one wood species it would be Walnut, simply because I like the way it looks.

Cranky Lubrication

 

Hi all...
A question for those of you using Cranky Crab wood gears.  What are you using to lubricate?
And a side thought...what wood species do you prefer?
Thanks

I use this software to customize gears and then print them out.  He supports spur, beveled, helix and herringbone teeth - very extensive. There is an English version available as well.

Re: What's On My Bench - The head of Medusa

I use an ESP32 microprocessor with the Arduino software development environment. There are libraries available for stepper motors, servos and addressable LEDs. The ESP32 connects to my WIFI so I can update code without having to have a USB cable to my project. I'm thinking of hanging my mechanism on the wall since it operates autonomously and because only the front is interesting. It incorporates a small PIR detector so it only operates when there is someone in the room.

I print using standard PLA plastic. I've tried a wood impregnated version but felt that it was too brittle. I typically airbrush over white PLA rather than owning an extensive collection of different filament colors. I recently tried a granite-colored version that I'm pleased with.

I bought some gears from Cranky Crab for my latest project and was really impressed by the quality.  Nice people to deal with, too.

Interesting, Mike.  I would not have thought to ask for custom.  You've shed some new light.  Thanks
