It's speed is variable but strings are wound at it's highest speed unless for special situations. Making a large wrap string takes maybe 8 seconds for a smallish scale and making a string for the top of the scale can take 20 to 30 seconds. I never timed them. The tail is make first then the swages are made. The tension of the string on the lathe is a debatable factor, variable from individual to individual according to their "thinking". The wrap is held in such a way that the copper goes on tight around the core and the coils are up against each other (they will spread apart when under full tension) so the copper will "crush" a bit, become oval in cross section). String whip is a factor and occurs at the antinodes of the string. This whipping action can cause the wrap to have differing diameters along the length of the string, from an inexperienced maker. > string to "lag" which would be a kind of twisting? No. Even hardened copper has very little spring to it, it is too malleable for that. No iron may well be a different story, I have no experience with iron windings. Speaking of "experience". I tried to make a couple of strings. I have one on my shop wall to remind myself that I just cannot do everything. I can do a few things but string making is not one of them. It is a skill that few can really, really master. Most lathes go in one direction. String makers hold the wire and the lathe turns in the direction so they can see the way the wrap leads onto the core. To see it from underneath would be difficult. :) There are tests. Before removing the string from the lathe you pluck it and listen to it. An experienced winder will know what to listen for, brightness, harmonic structure and extraneous noises. Ari Isaac listens to every string he makes, I have never seen Mapes winders listen. If Ari does not like the sound of the string he unwinds the copper and winds it again. (Yes Ric, the lathe _does_ go backwards.) Does that mean Ari makes perfect strings? No, but he is getting closer and closer and he is getting consistent results. Craftsmanship and caring helps a lot. Ok, ok, I'm crawling back into my cage. :) Have a great weekend all. Newton
