you misunderstand.

The Lovejoy is three pieces. One has a 1/2" bore, the other a 5/8" (or whatever sizes you need). the center piece is a spider. they mate, all centered nicely. Look up a google image for Lovejoy coupling to understand it better.

Thanks guys.. I think I've got myself setup.. we'll see. Bought a motor.. already have the MM-3.. and just called Grainger.

I didn't realize the parts each came separately.. Each coupling is a separate number as is the spider. Three different parts to make the whole...

Yippy.

Remember long explanations with lots of pictures and small words and multiple web examples are always best

No, I understand how the couplers work, the issue is with Jammin's choice of language....what he MEANT was you can get couplings with different bore diameters, but the same OD. What he SAID was you can mate a 1/2" shaft (from a motor or mill) to a 5/8 (coupling)

Perhaps he could edit to clarify

I ended up with the one Brew n Que recommended. Looks like it will be the most reasonable choice I could find.. When it arrives, I'll just have to build a mount for it.
