The smallest off-the-shelf taperlock is the 1008 size, and that size will fit your 7/8" shaft (and they are very cheap) https://www.bearingboys.co.uk/1008-Taper-Bushes/100878-Taper-Bush-Dunlop-2214-p The minimum hub diameter for 1008 is 63mm, however, and you are 10mm smaller than that. Also, machining for a taperlock is a bit of a game, and you need Whitworth taps (1/4W for 1008 size) which you probably don't have, More expensive, but much easier to prepare the pulley for, would be a Trantorque: http://www.fennerdrives.com/trantorque/_/Trantorque-OE-7/8/ That needs a 1 3/8" plain bore in the pulley. -- 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
