I am considering trying my hand at making a coil. At this time, all I have handy is CAT 5 cable. Has anyone attempted using CAT5 cable for coil wire (with the insulation left on)? Has that worked?
and estimated, can someone give me a clue as to how much wire a 7" D roughly say, 100 turns, would take?
I'm just considering using it, would it work ?
How much wire length would I expect to use in different sizes of coils, 7", 4", 10", 12". i'm not asking perfection, just a calculated guess as to what to expect.


Thanks

Cat5 cable is four twisted pairs of wire shielded with aluminum foil. Depending on how many wires you need for your coil, you might be better off with insulated speaker or microphone wire with 2 insulated pairs in a braided shield. Sometimes, cheaper is not better even if it happens to be free. You absolutely need the best wire to connect the coil to the machine. Don't skimp. Get the braided shielded wire.

The length should be 1.25 times the maximum you expect it to be. Wrap the extra wire around the shaft so you can extend or retract it as needed.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

If you are still looking for wire for winding some coils I may be able to help.  I have several rolls in a variety of sizes of very good quality magnet wire.  I also have some experience winding coils.  I'm in CA. but I would be happy to ship to you. I am new to this site and have not yet done any hunting.  I do have an old Compass CM-1 that I am in the process of restoring. (still need a few more posts to dl info.) Send message if interested.
thanks. lylej

Hello Mdiede57 . For VLF search coils do not use CAT5 the insulation will cause you problems so use only enameled copper wire tightly wound . You can use the wires inside the jacket of CAT5 for experimenting on PI search coils , but always do this on a metal detector circuit you know is working perfect . I never use phone wire for any search coils  , but not a bad idea if you have lots of time to experiment . Let us know your results .
Regards..........Eugene
