That would work well, but I doubt that is how the key-operated ones work, like this one http://www.ebay.co.uk/itm/Pratt-Burnerd-8-1-4-setrite-6-jaw-lathe-chuck-/331558619754 > Regarding how the 3 jaw chucks work I know how the _operate_. I don't understand how they _work_ It seems that the clamped-together assembly of scroll, jaws and work ought to be free to rattle around as a unit inside the main body by an amount equal to the running clearance of the scroll in the body. This page actually has a picture of the scroll and jaws clamping without a body: http://www.lathes.co.uk/taylor/page3.html -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
