Hi Brian,

Thanks :-)

Explanation: the movement is ideal ( I think in reality there would be some minor issues) according to my calculations by 1 Degree rotation of a Pinion the Track moves 0.15708 units depending on clock-wise or counter clock-wise rotation of the Pinion.

I hope this explanation helps :)

And thank you again for your explanation on how sin works in nodeeditor it helped me to have it work!
