Would anybody know if there is some kind of coating or paint, that I
could coat cooper wire with, to make some kind of homemade enameled
wire.

Thanks

Pure cooper wire is so hard to find, I don't even know why you would
consider such a dastardly act.

There's stuff called "Q dope" sold for this purpose. It's just a
variant on
clear nail polish. Modern coatings on mass-produced magnet
wire are superior to anything you can get at home. The 'Beldsol'
variant allows solder-through, which I find convenient.

When true varnish was used on copper wire, it was backed up with
a wrap of cotton (because the varnish developed cracks and wasn't
reliable).

No, it isn't "sold for that purpose". Q-dope is for high voltage
NODES. That would be the exposed connections between two endpoints on a
conductor in an HV circuit. It is made for sealing those exposed nodes.
NOT for "enameling an entire wire".
It's just a

GE had a paint, called Glyptal, that they used on electric motor, I
wonder if that would be any good.

I'm not sure if I'm going to try making my own enameled wire, but if
somebody had done it in an easy and effective way, I might be tempted.
The ideas I had so far are not "easy and effective".

Thanks

Short quantities of high temp enameled mag wire are available. Then
all you have to insulate with glypt or q-dope are the nodes which should
already be on your list of things to do. GC Electronics has the red HV
"q-dope" or whatever their brand is. Several hundred volts per mil
breakdown strength on that one.

Since I'm making strips of .060" thick and .500" wide and since it
doesn't wind too well, I think that I am going to do like Tim Williams
did and wrap a winding of maybe 10 turns one on top of the other with
insulation in between and put 3 winding side by side and connect them
in series.
It's probably the most efficient way to use the space that I have
around the core anyway.

Thanks everyone

When I made mine, I think I made 8 double edge coil sets.
Each started with the middle of a ribbon section diagonal
across the bottom of the slot in a wooden form wide enough
for two coils, side by side. I wound the two ends of the
ribbon into one of the coils, with the ends at the outside.
Then I removed the wooden form and tied the coils, wrapped
them with mylar tape and epoxied them into a solid unit. I
stacked 4 of these on one of the E stacks, with thin spacers
between, to allow for some cooling air to get to the bottom,
and epoxied the coils onto place. I trimmed the coil ends
so that each overlapped the end of its neighbor, and lap
soldered then in series. This way, I could connect the
coils on one E stack either in series or in parallel with
the coils on the other E stack.

If this doesn't make sense and you want to understand this
example, let me know, and I will take the camera out to the
shop and photograph the ugly monster. It has never been
prettied up, with one half just sitting on the other, with a
thin slab of plywood or something between the halves. But I
have been welding with it, off and on, for about 20 years.
It works very well, with my buzz box and a rectifier, giving
a very quiet arc with almost no splatter. With some rods
the flux forms a smooth scab that curls up and falls off
when the weld cools (wish I could remember what kind of rods
those were), leaving a nice clean bead. That never happens
with AC feed.

My huge inductor...
Seriously, I think I get a general idea. A picture would be nice
though, I always like to see how people put things together. I often
get idea from other people's idea.

Since photos are not allowed in this group, and you have
also been discussing this construction in Yahoo groups,
Electronics 101, I'll get a photo posted there is a few
days. I'll let you know when it is available.

Good, I can't wait to look at your contraption.

Thanks

Wrapping in polyester film, or polyester adhesive tape allows winding
flexibility of flat conductors, if sharp edges are not present. With
adhesive tape, placing a layer on one side only can be sufficient.

What is polyester tape used for? Is it specifically made to wrap wire?
Is it readily available?
