Recovery Rate of Wire Without A Scale

Thank you for this post Bejak. I can't help but think, however, that your calculations would only work if the density of the insulation is the same as the density of the copper wire. Density being: The mass per unit volume of a substance under specified conditions. As in the case of the Christmas lights, in a comparison using an actual scale to measure pre-stripped vs. stripped Christmas light wire wouldn't you end up with closer to an 16-18% recovery rate and not the 30-35% you indicate via your metrics? Thanks again for opening this discussion.

I did actually weigh some examples Christmas wire and strip it. Wanted to verify some results using the strip & weigh vs. what I have shown. The Christmas wire I did strip was around the 30% area. I do agree though that density plays a huge factor in recovery rate and weighing is the most accurate option. Just wanted to toss another concept out there that would get reasonably close for those that may not have a scale.
