Hi Terry,
The test rig just has a felt pad friction type of tensioner for the wrap wire - it works but it is crude and only suitable for testing.
I am not yet sure of the benefits but measuring the wrap wire tension as close as possible to the actual wrap seems to be favored so I am currently working on an electronic device which uses a rotating version of the conventional 'dancer' to measure the actual tension in a feed-back loop to a disc brake on the wrap wire spool. This will be fully adjustable, for the different wrap wire diameters, and provide 100% repeatable results - assuming it works.
The full size machine has just gone through it's third rebuild but I think it is going to be a long way off before it will be winding a full set of strings.
