I would take a completely different approach, I would make a fitting for the lathe spindle that takes R8 tooling. I haven't done this on my lathe, because I use BT30 tooling, but I do have a fixture for that. On my old lathe it was a block that screwed on to the spindle nose, but the Holbrook has a big enough spindle that the adaptor is MT4.5 on the OD to fit the lathe spindle and BT30 on the inside for mill-spindle tooling. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
