I spent several hours trying to draw a set of gear profiles in Corel DRAW X3 to be imported into LazyCAM to create a tool path for cutting the gears out on my router table. After many frustrating failures (lines were not connected close enough for LazyCAM to interpret as single entities), I started searching the web for a solution. I found the following web page:
http://woodgears.ca/gear_cutting/template.html
And after trying it out, immediately ordered a copy of the software. You can actually print out the gears directly from the web page, but the purchased version will output as DXF, or PLT files which are flawless where LazyCAM is concerned. I have already cut 4 gears out of wood, and mounted them with the teeth tips contacting the pits and the spin freely.
Just thought that other users of Mach3 would find this as useful as I have.....

Hey Mike,
For $23 bucks its worth it rather than drawing the gears if you do it enough. Some programs also include it in their software, i think BobCAd has it. Any way, good for you and glad it worked.
Thanks for the post,
