here is a gear that is ideal for CNC.
unlike conventional gears it is asymetric

I've just downloaded some of your stuff. I really like the looks of your 2003 clock, with its pendulum surrounding the movement. Reminds me a bit of some of Marc Tovar's work.

A CNC clock is one of the things I want to do with my router...maybe one of these days...

-- Chuck Knight

This looks like some of those mid evil gering sets. hmm
i may have to do some research on this :)
just to kill time. ;)

Gary,
Great website.
I downloaded the acad clock design. I'll probably have questions when I get into making one.
Bill

Gary,
Glad to see you'r posting in CNCZone. I'v enjoyed your website for many months.
Keep up the good work, and making plans available form your site.
Hager

Nice work!

--Alan

I'll have to get cracking on posting up the plans for the gear sets.

Can supply in solidworks format or dxf.

gary

I love your animations in your web site.
They show well what actually happens.

Thanks Gary

Please upload the soliddworks files! that would be great. that thing looks fun to check out. i can trade some SW files for it. ive got lots of fun designs.

Gary, do you sell your clocks? Are they easy to sell?
You have inpired me to make some interesting designs.

On your web site you show how to make the gears by hand, is that how you do them, or are you now a CNCer?

Oh and if you could post your DXF gear set that would be good too. Is the gear set of your high backlash low friction design?

Have you experimented with a motorized version clock? ( Probably a taboo question ? )

You have inpired me to make some interesting designs.
Benny don't you have a router to finish ?:D

There is something about gears that is really cool, if it wern't for the gears clocks would have little appeal except to tell time.

General reply-

No I don't sell clocks and probably wouldn't.

Coupla reasons:

way Too much effort.
I fall in love with my creations and find it hard to part with them.
They'd have to work. Too much tinkering to keepem running. People would ask for their money back when they stopped.

So these babies are strictly for the hobbiest.

About Solidworks et al....The files tend to be huge. Very hard to post up native files. There are ways to compress the files by suppressing features but that would mean giving the files to someone with a lot of experience with the program. If that is you and you have an FTP site I'd be willing to post up a few. I just don't have room on my webserver for this.

For now live with dxf. It's all you need really.

Iam not a CNC user except for generating files for the guys I work for during the day. CNC looks like an interesting hobby but not for me. Drawing the parts in the computer is enough. Still like to get my hands into it. Not looking to mass produce anything just yet.

here is an assortment of gears as dxf.

Nothing special, just works in progress.

Let me know if this is of use to cnc types.

gary

more gears

try these too.

still just a random sampling in need of cleanup.

Sure you guys get the idea though.

gary

Thanks for your hard work Woodman

Have you ever tried MDF for gears?

Joe (fellow Canuck)

Have been getting a lot of questions about using MDF for gear blanks.

This must be a preferred material for you CNC guys.

Nasty for the rest of us.

Nothing like the curl and smell of real wood. But real wood isn't the best choice for gears.

gary

MDF has a lot going for it -- cheap, stable, predictable, easily machined (and yes I said machined as oposed to cut), dense, sufficient for fine details...

It's a great material to work with. Only down side is that in applications involving "sliding friction" it can be iffy.

A question...M. Headrick's modified Graham escapement has been designed to minimize sliding friction...what escapement does your design use? (I admit it, I'm a clock nut!)

-- Chuck Knight

Woodman, when you say they stop working and you couldnt guarantee them, what is it that goes wrong with them? I still wonder about having a cyborg clock with a motor to do the driving and using the wooden gears. Has it been explored b4? The motor could be hidden in a hollow wooden shaft.

Ken Shea, I like fellows like you, you will untimately be responsible for me finishing my router. All I now have to do is fit the servos and gears and it will be up and running. I'm still reading that Mach 2 pdf :)

You are coming along nicely then Benny, that is great.

Got a question on Mach 2 over say TurboCNC?
will post it in the proper forum so this great thread does not get poluted.
Ken

DXF file for Clock 2003 is now available

Great website Gary, I love all of the clock designs
