Hello,,
I have a few questions about the Lego Technic Gears.
I have tried to draw them in a 3D-CAD program but I can't get the good tooth-
shape. (I have made a rack, and used this for "cutting" a gear-tooth in 10
steps and then copied in a circular array. The combination rack-gear works
fine, but when I use two gears, the don't fit together)
Is there someone who knows more (or a website) about the Lego Technic gears?
With kind regards,
Eelco Kooiker
