Did you look at the link?
It's not bare per say. It has a rectangular end but I haven't seen how to interface with that. Just machine a small pocket on a coupler with the same width as the end of the shaft? Use set screws on the opposing faces?
What kind of shaft end is this called?
Is there a manufacturer of couplers for that style or is it something I need to have machined?
I've been looking for days with no luck.
