I'm in the process of trying to design a spinning weapon for a 3lb bot. Assuming that the bot will have a top speed of about 5-6 mph and a weapon speed of about 10,000 rpm, how much "bite" should I be shooting for in a single-tooth design? I have come up with an easy to machine design where the tooth is about 0.25" longer than counterweight end of the weapon, but I need to figure out if that is enough or if I should adjust the design for more bite.
