Default best way of coating bare wire with enamel?

Any hints, tips, or tricks to applying enamel to very long thin
wires?
Everything I imagine ends up looking too "Rube Goldberg, like" to be practical.


This is continued from my bifilar winding thread.
Thanks

Put a pulley in a bucket. Pull wire through bucket w/enamel in it.

I need to do a couple of hundred feet at a time so drying methods would be very helpful aslo.
Thanks

Hair dryer blowing into a t-shaped tube with the wire passing through it?

I|I
I|I_
I| _ <- hair dryer here
I|I

Don't know how effective that'd be, but that's how I'd start.

Some of the commercial equipment I've seen draws the wire through felt pads that are saturated with the enamel. As for drying, I dunno. A few hair dryers?

Is this some special wire that you can't otherwise get with an enamel coating?

Enamel has to be baked with a specific temperature and time profile. Otherwise, you may have problems with adhesion and hardness. And given the material hazards, I'd think twice about this.

The enamel is UV cured on most modern 'magnet wire'. Don't try to do it yourself as it will lead to a fire or at least a short in the windings which can alter your voltage drastically. Contact someplace like Apex in San Fernando CA for really cheap prices on any gauge you could possibly want.
