RE: [TCML] Inductor Construction
Hi Tyler,
Do a search on floral accessories or florist supply. Here's my first hit,
these are #16awg 18" long x 12 per pack. I have seen these some more wires
per pack. This would make a pretty cool core if you use say 3" PVC or
whatever is suitable to your needs. Grease the inside of the tube, stuff it
with coated wire, and pour in marine epoxy (Ace Hardware). Presto, sliding,
insulated mild steel core.

Thanks guys for all the info!
Two quick follow-up questions:
Is the volt/turn ratio something to follow strictly? Would it be better to
under or overshoot the ratio if I had to? Just curious where it comes from.
And I can't seem to find the flower tie wire you speak of, Jim. Do you have
a link? I'll try to think of some ways to insulate welding rods in the mean
time.

Hi Tyler,
I don't quite understand your wire question. If you are asking if can you
splice the segments together - sure - just open the cable and remove the #8
segments, solder, and heat shrink the connections.
I remember a suggestion that you may want to consider: Not insulating the
rods creates eddie currents and subsequent losses and heat. Now you may be
able to pour some vanish in the tube (coat the inside of the tube with
grease or something to keep the varnish from sticking). I think a better
idea suggested was to use flower tie wires which is painted green and comes
in precut lengths! Mild steel is good.
Do a search on flower tie wire and you should get lots of hits.

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
