Nicrome: McMaster parts:
.0359" Diameter
1/8 lb. Spool 8880K75 $8.10
1/4 lb. Spool 8880K16 15.77
1 lb. Spool 8880K46 47.94
We got a pound, it's a whole lot. We've used around 50 feet of the spool we got, and have hardly made a dent in it. I'd suggest gettin' the q.p.
You'll also need some way of connecting this to power. At this point, you'll probably just want to do the easy thing, screw-lock it onto the business ends of some 110, and I don't blame you, but first, coil it. Coiling seriously increases the efficiency of the hotwire by an amazing amount, because the heat bounces around the inside of the coil and also compresses the air in there, giving you more heat for less.
To coil well, get a wood screw or a coarse thread machine screw, and wrap your wire tightly around it, then unscrew the screw out of the middle.
Once you've got a length appropriate for your application (around 9.0-15.0 Ohms for 110v, depending on how serious your effect is), you'll need to place this NEAR the stream of propane. Don't put it right in the middle, or it will get "blown out" by the cold propane, and never achieve autoignition temperatures while mixed with oxygen.
That's our test rig in action, and also why it's called "Juniper". We made NIMBY smell like a gin factory.
