Would it be possible to use something like this Hardinge Emergency Collet to make your own adapter?

Not a cheap solution but you could grip this straight shank ER40 collet chuck in a 1" 5C collet.

You expect me to read your post and pay attention?

You could always build one Steve...

Ed, The Maritool solution would work were it not for the very small "through hole".
Darren, don't worry, I could never ask a buddy to pay attention when I can't. What were we talking about?

I've decided to abandon the quest for an ER solution in favour of making a different spindle for the end mill grinder and mounting a 3 jaw chuck on it.
I'll 'splain further, with pics, when I get a round toit.
