RE: PDT (Pig) failure modes

"We" really want to know what failed and why!! Perhaps it would be eaiser
if I sent you a "saw's-all" :-))) But let's think on ways to find what
went wrong here... If it's just a pile of scrap metal... why not unwind
the %&^!%&^ thing by hand to find the failure.... If "perfect" windings
arced over, "we" be bad ;-)) If a defect became apparent, "they" be
bad.... Considering the rarity and expense of these things failing, it's
not a big deal...
