Re: Drive-train shaft size

For our arm joints we used shafts that were 1" or more diameter. I can't remember exactly. I know they took a 1/4" key. You can see here Massive torque when you take a van door motor and gear it down another 20:1 We were able to bore it out a bit inside to save some weight.
