I would guess that 90%+ of FRC teams could find a machine shop willing to do so in less than an hour of calling up shops. Just for reference, when we do this it takes no more than maybe 5-8 minutes to face a shaft to length, and turn both ends down to fit into a bearing. So you're talking about maybe an hour tops to do all of the shafts in your drivetrain. I really don't think you'd have a difficult time finding a shop to do an hour of work for you (especially since it's all manual and involves virtually zero setup time).

Unless you want the bearings in the middle of the shaft.
