I turned an adaptor for the end of the lead screw. Onto that I put the 40T pulley. The motor has a 20T pulley.

Subject: Re: [digitalhobbyist] #MISC Pulleys?
The lead-screw on my lathe is about 20mm diameter and 3mm pitch so very
close to yours.
I run a 3Nm stepper on my system with a 2:1 drive. A 40 tooth HTD pulley
on the screw and a 20 tooth on the motor using a 5mm pitch 15mm wide?
HTD belt.
Belt and pulleys should be easily available from a good stockist, though
in fact I made my 20 tooth pulley.
Do not even consider using round belting to drive a lead-screw if the
ultimate aim is some sort of ELS.

Looking?for pulley and belt suggestions.
I have 3.10Nm stepper with a 8mm shaft.
My leadscrew is 3/4 - 8tpi.
The stepper has been criticised as to small for that leadscrew and
suggestion to use pulleys.
So where do I find a pulley with a 3/4 bore and a matching (smaller)
8mm bore?
Most 3/4 bore pulleys use a 4L V belt.
I wonder if I could use some round urethane belting? A 5-6 mm round
belt might run in a 4L grove.
