Slightly more dimensions here: http://www.harmonicdrive.net/products/rotary-actuators/hollow-shaft-actuators/fha-c Bores are slightly larger than size-code. The larger sizes might make it easier to mount a D1 spindle nose, but the problem that 6 into 8 doesn't go remains. FHA17 has 6 holes, but is probably too small. -- 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
