These prints were not made to correspond to my organized Plans A, B, & C so they are kind of a mish-mash. Pick and choose as you see fit.

Please check dimensions for us. Check fits and tolernances too if you know what you are doing in this area. Report errors and clarifications needed.

Thank you very much for the drawings.

I see one problem: The dimension given on the square end shaft is 8.633±0.013. The problem I see is the hypotenuse of this square, as toleranced, will be between 12.191mm and 12.227mm. The smallest dimension for the hypotenuse, 12.191mm is equivalent to 0.480" and is larger than the ID of the bearing (0.472") on the 56mm Banebots transmission.
