I'm considering building my own b/c axis. The Doughty drive is great, but I'd like to be able to use a larger motor. New harmonic drives are well over $1k each so I'm stuck at looking at ebay. I stumbled on this set. Would some one help me figure out if this would work? I figure the center piece goes into the piece on the right. Where does the piece on the left go into? How would I go about attaching a stepper motor to something like this?
Thanks in advance.
Jim.
