Re: [TCML] Inductor Construction
Dave -
Tyler is not trying to create a parallel multifilar winding, he is just
trying to quickly and easily connect all the physically-parallel conductors
in the cable into electrically series-connected conductors. Since all the
conductors "start" at one end of the cable, and all "end" at the opposite
end of the cable, I don't see how one can "easily" connect the end of W1 to
the start of W2.
A sketch showing exactly how you could the connect the end of W1 to the
beginning of W2, etc without completely disassembling the cable into
individual conductor segments might help me to visualize your concept.

Tyler,
What you are proposing is to create a multifilar winding. Bifilar
windings (two wires in parallel) are relatively common. I've seen magnet
wire offered with 4 conductors bonded together. No reason you couldn't do
6.
If you arbitrarily number your wires 1 through 6, just apply power to the
start of winding 1 (W1), connect the end of W1 to the start of W2, the end
of W2 to the start of W3, and so on. Power comes out of the end of W6.
Only downside is if there is a thick insulation jacket around the overall
cable. It will take up space and trap heat. Also, generally, jacketed
cables are more expensive per net foot of conductor than a single
conductor. Still, if you can get the stuff cheaper than a roll of 8 Ga
THHN at Home Depot, go for it!

I apologize for my rustiness with classical physics, but here's the
problem:
I'm building an inductive ballast for a pole pig; the plan is for 200-300
turns of 8 gauge around a PVC pipe, with some welding rods taped together
into a long bar sliding in and out of the PVC form.
My question arises because I found a supplier of some cable that has 6
strands of 8 gauge insulated copper wire inside. Would I be able to
somehow splice the input to connect to all 6, then use say 50' of the
cable to get 300 turns effective?
Is this feasible or not?
Thanks,
Tyler
