Go to Post If we can transform our culture to the point where girls swoon over guys as they pull their dremel off their belt and carve some speed holes in a smooth fluid motion, I think FIRST is half way to its goal. When we get the guys to swoon over the girls for their hot moves on the 5-axis, we have won. - EricVanWyk [more]

Re: Where to get lightweight flexible coupling?

Not sure where you can still get them, but it looks like you need the C100 hub style. We used the Nitrile (Buna-N?) spyders in the past since they are the softest and offer the most misalignment error.

You would need to make a sleeve to make the bore smaller as Andy has described in the past. Simply broach a hex in the coupling and make a corresponding insert out of aluminum or steel with the 1/2" keyed bore you require.
