Re: Noob question - shaft couplers

Hello,

yes, these are my steppers, nema 34, 600 oz-in and nema 23, 260 oz-in.
They have 1/2 and 1/4 inch shafts and they need to be coupled to a 10
mm threaded shaft and 6 mm plain ( not threaded ) shaft ( which are
the main lead screw of my lathe and my transversal axis screw ).
