Even my 10" coil with a jig was hand wound. I used a VS drill only to turn it while coating it and letting it dry.

My first two tesla coils, running of a NST, used handwound secondaries.
The first was on a cardboard mailing tube, the second on a piece of
pipe. winding length on both about 18"-2 feet long, 3-4 inches in diameter.
One coil I built, start to finish, in less than a day, and it had a
handwound secondary.

You just sit there for a couple hours with your spool of wire and your
tube, and a scotch tape dispenser so you can tape the wire down
periodically. It really doesn't take that long to put 800-1000 turns
on the tube. You can easily do 1 turn second (try it), and 1000 seconds
is less than 20 minutes.
In fact, my first attempt to do a machine wound secondary, using a
lathe, was quite the adventure.
If I had to do it today, I'd use the variable speed electric drill
approach, and still do the wire feed by hand.
