Plug in the size of your cog and the number of teeth you want, and out it pops. If you've got any suggestions on improving this tool, please let me know via the contact link in the menu.

Cog dimensions
Optional parameters

This is the thickness of the inner circle, it fills in all teeth. Making this equal to the inner circle value gives you a solid cog.

Colour

By mixing Red, Green and Blue you can get any colour you need.

Foreground
background
Spokes

Rather than being only solid or hollow, this adds a variable number of spokes to the cog. Minimum of two.

Note you'll have to generate it first!

Version 1.5

  • JS/ SVG version. A new version that creates a new SVG cog, which is much more scalable.

Version 1.4

  • Application now gives you a link to save your cog in JavaScript mode.
  • Background colour can now be set, transparency is out.

Version 1.3

  • Added spokes, mooring circle and hole, on request.
  • Transparency seems a problem, as the background image is required for alphaing. Pondering giving the ability to choose background colour instead.

Version 1.2

  • Added jQuery so the page will reload the image without reloading the whole site.
  • Now makes an image 4x the required size, then shrinks it by four to perform some image smoothing.

Version 1.1

  • Much better colour picker
