### clockit: Free 3D Clock Designer

Posted: Fri Jun 05, 2015 7:21 pm
Catched by forum user clockit's clock virus in his very interesting thread ( http://www.shapeoko.com/forum/viewtopic.php?f=30&t=6186 )
I have started a new program. I hope this is a little bit helpful for designing wooden clocks.
Construct the placement of all your wheels and pinions and save it to an SVG file for further use with Inkscape.

See the second version which now provides also 3D-view.

Have fun with clockit

GrblGru you are the man! Can't wait to test drive this app, thx! I guess I'm going to have to figure out that whole module thing, I've based my calculations of of diameteral pitch... Maybe you'll be building yourself a clock sometime soon... if you need anything, just let me know and thx again!

Module and diametral pitch are like liters per 100 km and miles per gallon -- different units, and one is the reciprocal of the other. Or, closer to home, like metric thread pitch (this many millimeters per thread -- larger number is coarser) and imperial thread pitch (this many threads per inch -- larger number is finer). The diametral pitch is the number of teeth per inch of gear diameter. The module is millimeters of gear diameter per tooth. Same thing, only expressed differently.

cvoinescu, I agree with you. To make it easier I have added a new input 'p = Diametral Pitch'. If you enter p the program will calculate the module.
In the {Menu - Extras - Settings} you find the control 'Metric' to choose metric [mm] or imperal units [in].

New version V1.2 is available: https://goo.gl/RgVtWn

the way that you explain it, it's makes so much sense and seems pretty straight forward to calculate. Thanks for the explanation, I'm on a bit of an island here, I don't personally know a single person locally that build/cut gears let alone clocks. I never really had a need before to use module, when I was drawing them by hand my method worked.

But thanks again for the help!

GrblGru, again, a huge thanks goes out to you as well for adding the pitch for me. I posted my process for cutting gears in the other thread and when you read this you will see just how many steps that you are going to save me! I wish you lived close, I'd give you a clock, lol... I'm going to go down load it now and play with it, thx again!

GrblGru, love the app, works great! I really appreciate that you accomodated me with the imperial measurements, thanks! I ran a bunch of profiles through it and the numbers that it generated were spot on, looked great, and was fun to do, so handy! I did encounter one issue, when the program open the file in Inkscape the wheels were a third of the size that they were supposed to be, I don't know if it's something with my Inkscape setting or what... but I was able to scale them and they seem fine...

Hi all,

I've finished a new clockit version v1.3. (available at https://goo.gl/RgVtWn)

What's new ?

- Fixed the size problem from the SVG-Export
- Showing the arbor, also in the SVG-file
- DXF- Export

By the way. It is now possible to load SVG-files with the new Estlcam Version 7.623.
So, you can load the clockit output direct into Estlcam.

Have fun with clockit

Thanks for this program and the update on EstlCAM. I've been sitting on the fence about that package and will now pull the trigger.

GrblGru, you are the man! Love the new program! You're making my life too easy, lol... thanks so much, I really appreciate it! If there is every anything I can do for you just holler my friend!

PS: I've been using Estlcam since day 1, I love it... thx for the taking that into consideration!

clockit, it's YOUR knowledge. I'm only the programmer, who like to learn a little bit from you.
But ... if I had one free wish. It would be great if you can tell me how to design the escapement.
Especially the shape of the escape-wheel-'teeth' is interesting. Same with the anchor. How do you design it by hand ? Is there some mathematics available ?
