    J 325 6000rpm spindle

    I have a J 325 with a 3500rpm spindle and I'm wanting to upgrade it to the 6000rpm setup but the pullies are no longer available! So does anyone know what the outside diameters of the pullies are for the 6000rpm setup? I have a cnc lath so it shouldn't be a problem making a set or two. Thanks

    Bob at ZPS told me that there is a jumper wire that would have to be changed. I don't know for sure.

    Well I looked and I have a 1500/8000rpm motor and a 2.800'' drive sheave and a 6.400'' driven sheave so if my math is right I need a 4.800'' drive sheave and that should get me to 6000rpm!!
