I had wondered and pondered the same thing, and in the process of
designing my system have made it so that the flat primary can be
flipped. After reading the posts in regards to this matter, I guess I
devoted too much effort on this account. Actually, (unless dyslexia is
setting in on my mental image), flipping a flat primary will reverse the
winding direction, however, the direction of a tubular secondary winding
will remain the same...
Hence I designed a "flippable" primary. But if it makes no difference,
guess I can secure it in place!
