Someone here might know where to get the thin heater wire (insulated

Locally, try "smoke shops" People into e-cirgaretts use this wire. It
comes in different gauges. Amazon sells the same wire for the same use
It seems that Kanthal A series (FeCrAl) forms an aluminum oxide skin
which is an electrical insulator.

From the size and number of turns, 30 on the bi-metal arm @ .125" wide
= 7.5", and measuring a 0.004" diameter or 38 gauge and 53 Ohms per
foot, I get 33 Ohms which matches what I measured while troubleshooting
the instruments early on. This should do it:
