Stepper shaft couplings - can you ID these?

[HankMcSpank]

Help, my "can you ID these couplings thread" has morphed into a fledgling technical debate" :-) (there must be something in the air around these parts?!)

Thanks for all the input...I guess the answer is "no, you can't buy 'em"...so when it comes to it, I'll have to get a better one made than the one I made myself......I'll limp on for now as it does work.

Thanks for the offers....I'll take one of you up on it when I get past my "make do" phase (which - using past history as a precedent - this phase will last far longer than it ought to)


Next question....where do you go to get a heap of 1.6mm thick mild steel in small rectangles made? (something like 4mm x 7mm x 1.6mm) ...I've looked in the local rag, but there's no "Small steel rectangle makers" in there!

Or if you were faced with having to make a few hundred....how would you approach it?
