well, i tried polishing the shaft, but end up ruining it when i got impatient. i redesigned the shaft with tolerances more on the minus side, and i told the machinist i will pass the optima mid top gear and the B4 slipper plates to him to do a matching test before giving the parts to me. hopefully by tommorow morning i can pass all these parts to the machinist to start work, and in another 2 weeks get my working prototype. the good news is the length i designed was almost spot on, so i shortened the shaft a bit by 0.5mm. i tried putting the gear cover on, and definitely a hole must be made on the side and a extension cap made to accomodate the new longer shaft end.
