1) Use 1/4 turn sections of the copper tubing and link each 1/4 turn
section together with massive copper blocks, 5 x 5 inches square x 6
inches long. Butt the primary 1/4 turn sections together and use a
lot of brass setscrews to firmly capture the 1/4 turn sections in
the brass blocks. I'm worried the resistance might become an issue
with nearly 12 "copper connectors" joining the pieces together. I
would like to use he large 4 inch copper tubing but it seems joining
them together might be a problem, and trying to haul it assembled
just will not work as the height would be too much for interstate
bridges and city streets with cross-wires, etc.
2) It's not possible to use 2-3 inch dia. copper cable as the weight
would be too high for assembly handling.
3) Perhaps use 1 inch dia copper cable and then wind 4 of these 1
inch dia. lengths in parallel to form the 3.5 turn
primary. Handling 1 inch dia. copper cable should not be too much
of a problem for a crew working with a small crane (which we will
have onsite to erect the sec coil and attach the large toroids).
With this idea, I probably would join the 4 cables together every
1/4 turn with some solid machined copper clamps to insure even
current distribution in the primary.
I know there are some great thinkers on this list and a few good
machinists, so ideas please!! We are open to consider every idea
and try to adopt the one we think will work best.
