1640 has access to 2 drill presses, 2 vertical band saws and a horizontal, a miter saw, a lathe, and MIG welder. We also have a sponsor who can do off-site milling. We've never created our own mecanum wheels, though we investigate it occasionally. If I'm still supposed to answer #3, seems to me it's (robustly) securing the rollers in the correct orientation.
