That's awesome! Thanks so much for making those measurements!
That'll really help with my planning.

Using a FET would be pretty cool!
I set up my cutdown for the current measurement. I used my DMM on
the 20 A scale. When I made the connection, the DMM spiked around
5 A. After a several seconds, it settled in around 4.25 A.
The cutdown power supply for the nichrome is three Energizer
Ultimate Lithium AA batteries. The energized length of nichrome
is about 3/4 inch. I used 26 AWG nichrome 80.
