I made a 12.5" secondary wound with #18 wire for approximately 1100 turns (
about 50" worth of windings) It
used a full 9lb. roll to do this. so you can figure about .2 lbs per linear
inch -at- 12.5" diameter ( this
should also give you a bit of an excess buffer for kinks and mistakes....
hope this helps ...
ummm vertical winding ????? sounds like a real challenge ... I prefer
horizontal winding, much easier to
walk to the side than to lift upwards as it goes on.
