Hi Art,
Here's my go at a ticker.  I've used the dimensions of Scimitar with respect to the gears and the ratchet mechanism.
I don't use bearings just steel on wood and I usually use 1/8" shafts.
All the parts are cut from 1/4" baltic birch and the visual part is just a simple interference pattern from 10" toothless wheels.  It works great on the test bench.

I had to clean (snow blow) about 1 Km of road to get to my CNC which is at the summer cottage where my CNC lives but it was worth the effort.

The Ticker is certainly not finished as the back is just solid wood and that will change in the future but my time has run out.

When finished it will be a shelf unit - no wall space left.

John

Nicely cut. I see some awfully small spokes in there somewhere. :)

Hi,
Yes there are some very small spokes in there I reduced the minimum size on pinion in GT that would still produce spokes (down to 1" if I remember correctly).  Its the same spoke pattern as on the drive wheel - just smaller.  Since my spindle is very small and driven by an RC motor I can't handle anything bigger than 1/8" cutter.  These components were all cut with a 1/16 router bit at 60 imp. 

I've had to leave the "bush" so it will be some time before I can go and play again but I will post when It gets done.  Ultimately it will be spring driven and I have no idea how long it will run. We'll see.

Almost complete

I had a little time last night and was able to get the vanes installed.
The vanes were styled after one Mr. Roy's pieces.
I think I will call this machine Sunset.

Excellent job Randy. I like it.
Let us know how your family and friends react. I'm
curious about that. Yours looks as good as mine, and
Ive had great reaction, everyone seems to like it and get
mystified by it. On the other hand Ive heard
some say that their wives wouldn't allow it in the house.
  (My wife is pretty picky about decorating, but loves the ticker
and my first wooden clock. )

  I say hang it with pride, Ill bet you get hints about making one for others... :)

My wife vetoed the idea of putting it in the house.  She hates the click! 
I may just build one and put it on the bedroom wall  ;)

Hello,

I made a 3D model to understand how it all goes together. I hope this helps clear up things a bit. I did make PDF?s but there are a few minor modifications as you can see in the video.

Also: Thanks to Ed R. for the help.

  Most excellent. Man, that was a lot of work, kudo's.. It probably clears up tons of questions
people might have. Thanks for the work, I do appreciate it.

That will save others a lot of thinking and guessing also a super nice job on both the modeling and the ticker.

Thanks, I had an issue understanding some of it and Edward Ricci took the time to explain. Masterbrew offered to help as well. Masterbrew just completed his vanes and has a new video.

I appreciate the plans Art and I hope you do more along with the others here. It takes as long to do a 3D Cad model like this as it would to actually build it. Ha! If I don?t do a cad project every once in a while I start to get rusty plus I always enjoy it.

Best Regards,
BillJ

Hey Bob,

Ha! - Yeah my help told me that until you have the parts in your hand it is hard to understand. That was a nice thing to tell me anyway.  :)

Here?s a couple of neat wood working videos that some of you might enjoy. They both use hand tool construction which is off topic but one is an artistic clock escapement.

Hi Bill;

I understand what your saying, often by seeing you can quickly relate to what's going on, that is the part I like most about your video, well done.... I also love the rocking chair build, however I'd be a bit concerned with the wood working mojo between an axe and I and to anyone around me.. lol


Thanks for sharing..

Cheers
Bob
