The yellow, non-stretchy, thin stuff is polyester (Mylar is a brand name - of 3M - I think) - look for the yellow roll on the page. These prices are a little cheaper than standard pricing.
5. Woven fiberglass sleeving
Skycraft Parts & Surplus (See #6 for contact information.)
6. Secondary winding
a. 16ga solid copper, silver coated wire. Somewhere around 90' or so. 131 turns seems to fit well. A bit more turns if no longitudinals are wound underneath.

b. Home Depot for some 0.080" weedwacker line. This was cut into 133 little pieces 1.5" long each.
c. Vitamin C powder bottle
7. Secondary Winding Tool
I had to make up a small spool that could pass through the toroid hole. This was made from a 3 1/2" long piece of 1" electrical PVC tubing solvent welded to a couple of 2 3/4" diameter discs. These were cut from 1/4" PVC sheet. I turned these on the lathe so they would fit over the ends of the tubing.
8. Primaries (3 or 6. Recommend 6 primary windings)
20ga solid copper, silver coated wire
Same source as #6 above
Hex Controller

Excelent -- a private space :)
I have a core now but am about to run out of time untill September. I will be availble on-line but because of business travel I wont be able to experiment.
I do hope to get a few hours this weekend to do some basic experiments on longitudinal wave transmission -- I have a stack of long solenoid coils (for various tesla coils) laying around that I want to do some tests with. As it's a capacitivley coupled advanced wave we want I have some ideas I want to test for more efficent drives... I'l post some photos whatever happens.
cheers
Mark.
