Supermax 1338 crossfeed acme?

Is it a left hand tap? for a crossfeed screw, it needs to be left hand.

The crossfeed screw is left hand and you want a left hand nut correct

As said above it's more than likely 5/8 left hand. Acme stepped taps are expensive.
you could buy some 5/8 LH acme rod and make your own tap. I did this while making a new nut for my lathe. I had a piece of acme rod.
