Thanks for replying Tim. I use a 10:1 winder as well. A Geauga. For me, I feel I have always wound too fast so I'm trying to quantify my winding and get control of the process.
 
My thoughts along the lines of a CNC winder are more in the rubber testing and data gathering arena. Although I wonder if some of the variance we see or think we see in rubber comes from us and our winding. I do Quality Assurance for a living and a good deal of what I do involves Statistical Process Control and the elimination of causes of variation so that definitely is enfluencing my thinking here. There is a strong tendancy in my work to remove or positively control operator inputs as much as possible because they are inherently inconsistent.
 
I've heard of some folks using a metronome to wind with...

Hi Bill - I don't know if this is what you  mean... but I've always used a 10:1 winder. So I've got used to a certain personal tempo/cadence of winding...   faster at the beginning and slowing as I get nervous about the breaking strain  :-)  but also the straight line tension vs what the  torquemeter says. I think anything that puts some numbers against what your 'instinct' is telling you can help clarify that. It's an interesting way to think about it, though there's so much variance in rubber across batches, temperatures I don't know how you'd program a machine to think it through...
cheers
