How to Draw a Gear in Turbocad Deluxe

For you that have TurboCad Pro/Plat drawing a gear to specs is as easy as using the gear contour Tool, but if your limited to the deluxe version then that tool is not available. Altho it takes a little time, the outcome is pretty good compared to pro/plat gear tool results. Hope this helpful. Enjoy

FCB is 1/20 of the base circle radius (base circle radius*1/number of teeth)
ACB is 360 degrees / NCB
NCB is number of times that FCB can be divided into CB
CB is circumference of the base circle
Here is the reference I used; http://www.cartertools.com/involute.html
Hoped this helped.

August 2014, with time on my hands, and having bumped into a post by Murray (I seem to recall) that used the term "involute gear", I went on a Google search to find out what that meant.

I happened into the same "cartertools..." website that Ed just linked.

I enjoyed creating a gear using the instructions in that article (I like following instructions... making repairs, a recipe, or building stuff from instruction).
Below is from August 2014, via TurboCAD 19-Deluxe.  It would have been simple enough to make it 3D.

Thanks, Ed.

Those who have 2016 Pro can use the Curve From Law tool to draw a true involute rather quickly.
