Hi guys,

Do you know where I can find Spur Type of gears files in different ratios?

Or point to a free software that I can design gears to cut on my laser machine?

Thanks

You could use Google SketchUp with the involute spur gear plug-in, and then export to dxf using the stl/dxf export tool.

If you prefer a standalone program, this might work for you... http://www.forestmoon.com/Software/GearDXF/

Web based option, but only saves in HPGL... http://woodgears.ca/gear_cutting/template.html

Zax.

There is also a Gears option in Inkscape. Only issues I've found is that the gears are scaled bigger than actual gears which may be what you need/want. You can export in several formats including DXF.

Thanks guys, downloading now to see how they work.
