Do what that chap Edward's link seems to have done, use an ER11 extension spindle as your basis: http://cgi.ebay.com/ER11-8MM-STRAIGHT-SHANK-CHUCK-CNC-MILLING-LATHE-D66-/150573752140 or 16mm dia, but needing a snap-ring groove or something http://cgi.ebay.com/New-C16-Er11-150L-Milling-Straight-Shank-Holder-US-/110452460881 ER11 goes up to 17/64". Then use the water pipe as you originally intended, with some $5 angular contact bearings to suit. (8mm and 20mm are easy, 16mm would need sleeving up or machining down, as there are no 16mm ID angular contact or taper-roller bearings. My hobbing axis uses the same idea, but with an ER32 holder and taper roller bearings. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
