Thanks Pete.
I guess its mainly the ability to be able to dial in an already round part that I'm after, so even though I was thinking small 4-jaw a 3-jaw would work - dialing it in using the outer 4-jaw as required.
I've already got a few ER32 collets for the mill and was planning to work out some form of collet chuck to mount on the backplate or or in the internal spindle taper, but I guess a collet block that I could chuck in the 4-jaw would be handy. Would cover that small size range up to 20mm.
Would still need something to handle between 20mm and ~30mm though...
Good thought about attaching some jaws with a smaller face - I'll think more along those lines too. If I could make some up that located over the main jaws well enough that they weren't a PITA to use it could work well. Even if it only handled that missing size range between ER32 collets and the main jaws.
