I am wondering about using the wires from the focusing/deflection coil windings. They are basically enameled magnet copper wire. The gauge varies depending upon the size of the CRT gun but I think they are usually 26-36g and they have an enamel and a high voltage rating.
I've uncoiled many of these and have made spools of them. I separate each thread (usually 5-6 per coil, all same length). So one winding would make 5-6 spools of about 100ft each.
For a few different applications, having very flexible well insulated wire is very helpful and having as little outer insulation that is thick and fairly inflexible is very helpful. I've tried car audio wire of 4 -0 gauge and the insulation outer wall thickness is more than that of the wire in many cases! This is to protect against abrasion in automobiles.
The plan is to determine the needed length of wire (let's say 10 ft) and then make a bobbin/spool that is maybe 11ft (gives 6" leeway on each side), and then wrap the wire around the bobbin. The number of turns determines the gauge. Once the desired gauge is reached the wire is cut and heat shrink tubing seals the ends to hole them together. Then the wire is pulled through heat shrink tubing (300v rating, some 450v or 600v) and heated to shrink. Now the wire has the enamel insulation (HV rated) as well as the shrink wrap insulation. The ends of the wire are cleaned with a solvent that removes the enamel to allow contact conductivity.
My main question is whether I should remove the enamel from all of the wire or if removing just the ends is sufficient. The ends will be soldered into a solid wire so I don't think there is any issue with lack of contact - but - there will not be contact throughout the inside of the wire which IDK if this matters or not. This is my main question and concern and want to know fi there are any other things which I should take note of.
This wire is going to be used for low voltages from 2-14v AC.
