John,
We appear to be takling about apples and oranges. The size of a single
strand, and the finished size of the whole stranded wire containing the 36
strands.
If a single strand of the wire measures .001 inches, that is 0.0010 inches,
or 1.0 mil exactly, then that changes everything. That single strand is 50
gauge (50 AWG) according to the tables.
My original guess of 44 or 46 gauge (44 AWG or 46 AWG) was for each
individual strand, and was based on your original statement of a single
strand being 1.5 mil, or 0.0015 inches. That is why I suggested that you
carefuly measure it again.
I still don't see how you were comming up with gauges like 30 1/2, 31, or 32
for a single strand. Is it possible that you trying to state that the whole
stranded wire (with all 36 strands) was approximately that size?
JaMi
