We're looking for a supplier of Lovejoy-style jaw couplings like those 45 used last season to switch out its gearboxes between The Mighty Auk and the ball drive robot. Lightweight and small are the most important criteria, of course.
Can anyone recommend a supplier for these couplings? I've already checked through both MSC and McMaster-Carr and, while they have some available, they seem a bit too heavy-duty for my needs.
The link that was provided last season to the MSC catalog page from which 45's couplings were purchased doesn't seem to point to the same place anymore.
Thanks
