Notes:

Fiberglass sleeve used - HTG fiberglass, does not fray like standard high temperature sleeving (1000F) and is rated for . See [1]. Note that the resin can burn out at the 650C (1200F) workign temp. Sleeve has VW-1 flame resistance. Made of fiberglass, it does not burn out, but may fuse and lose fiber structure.
Inner core: 5' long wraparound of 2mm tight braid fiberglass sleeve - 600C - [2]
This is packed into 6' of 6 mm tight braid fiberglass sleeve.

Theoretical idea:

But, ga 18 can't bend easily using a cordless drill.

20 feet of 20 ga wire appears to be most convenient - 1 piece, max at 1200F. Current 500W heater is 1200F max, and works well.

14 feet of 24 ga works perfectly by hand to get a good wrap over 4 feet, and goes fast, about 1 minute pending tieups:

Cut 14' of ga 24 nichrome
Cut 5' of tight 2 mm fiberglass sleeve
start the wrap of nichrome on one end of sleeve
Attach other end of sleeve to a free-spinning rotor
Once enough to go inside a cordless drill chuck - grab the nichrome wrap and turn on the drill in reverse to start wrapping. Tension the sleeve against the rotor
Wrap away! A person should be able to wrap 4 feet long just by holding a corless drill
