Where can I buy some small wire ( about # 28 to 30 ) that has the enamel
type of insulation that can be soldered and the heat will melt the
insulation ? There was some on ebay I bought that did not seem to work.
After checking it out, it seems that it needs to be heated to almost 400
deg C and when I tried that, it did not do all that well.

Before I dive into the magnet wire selection swamp, have you
considered using a chemical stripper or abrasive stripper?

For chemical stripper, I use common furniture stripper (methylene
chloride).
Dip, wait about 15 seconds, wipe clean, dip in flux, and tin in a
small solder pot:

I don't have one of those. I use a stainless tubing endcap attached
to a big soldering iron with a hose clamp. Ugly, but effective. I
haven't measured the temp, but I'm sure it's less than 400C. Oh, they
make a commercial version of my kludge:

The down side of chemical stripping is that it's slow, but if you have
a bunch of wires to strip, you can just clump them together and dip
them in stripper simultaneously.

Drain cleaner allegedly works:

but looks dangerous.

For abrasive magnet wire stripping, there are machines and tools
available.

The problem is that #28 or #30 might be too thin to do with some of
the tools. Try it with some sandpaper. If that works, you have a
chance. If you want to get fancy, grind a slot lengthwise down a pair
of tweezers or pliers that fits the wire diameter. Dump the wire end
in some abrasive powder, clamp, and pull. You will probably need to
do it a few times. I do this when I don't want to play with the
chemicals. Tin when done.

Ok, on to the vendors:

gotta run...




If OP is willing to have a solder pot running he can crank that up
to 400 and just dip the ends of the wires in the pot. That would
tin the ends and make them ready for soldering to the board.
