If it wasn't clear, I'm also a fan of the Greyhills.
We've had great success mounting the 63r directly into the hex shaft.

We drill a .25 hole in our shaft with the lathe, then using a bit of hot glue push the encoder into the hole. Zip tie the wires to something rigid nearby and you're in business. The only thing to be wary of is ensuring that your tail stock and chuck head are aligned correctly, if they aren't the encoder will wobble quite a bit when the shaft is spinning.
