i'll post pictures tomorrow. the z is adjusted by means of a 1" bolt and two nuts, above and below the housing. The table is pretty much stuck, this machine has sat for some time. i bought it dirt cheap as a possible project. the motor on the bottom is nearly the size of a 5 gallon bucket, i suspect its 3 phase, but there are no markings so i am not 100% sure how to tell. it looks like it has 4 wires going into it...
