Another great video Tom, god I wish I'd bid more on that Hardinge.
I get lazy and cut the whole thread with the cross slide. As an excuse I have a scale on the compound, so I keep it dialled in parallel to the bed, then can use it for fine feed on that axis.
Speaking of course, my Summit goes to 1/4 tip, I've never even tried it. Would imagine that would only be cut on multiple start treads. You can unlock the spindle and index the gear train for up to 6 start threads.
