There has been much talk on this topic - mainly suggesting alternatives.
In support, I accidentally found a plastic pipe manufacturer while looking
for 90 degree elbows to join for a toroid former.
Noticed some nice 300 mm (12") PVC pipe ........ thinks, "this would be
better than the 6" secondary I have at present."
Asks the nice man, "how large do you make these?"
NM: "We do PVC up to 300mm. We have HD polyethylene which we use for
larger diameters, up to 1 metre" (thats just over 36" for you guys -
perfect tube, off the shelf, no welding, any length you like)
Now this sort of thing has to be available in good ol' USA. I'm in
Adelaide which is by comparison a large country town ;-)
