 Thanks Jim, when making open springs like valve springs I cut a coarse thread on the form to use as a guide when winding, spinning the form in the lathe. I tried freehand but the results showed in the spring, the guide gives uniform spacing. The lateral cuts would make it difficult to hold together and turn in the lathe.
