Re: pic: Team 948 2-Speed Ball-Shifting Gearbox CAD Drawing

looks great! congrats. I was curious from both you and anyone from 222 that reads this.

1) how do you cut the grooves for the balls? do you just use an end mill or do you get them wire EDMed.

2) What kind of tolerance do you need to hold on the shafts and gear cuts to make the system sloppy (reduced torque transmission)?
