gonna by some wire for TC

[greenbrucelee]

Seriously, why use a profile for Ni200 on a NiFe30 wire when there's a .csv profile for it. NiFe30 is 492 TCR & Ni200 is 600 so quite a difference if you use the wrong TCR or .csv.

I didn't know what tcr was

TCR is a line between 2 data points. usually lowest & highest test temp. Some come preloaded but you can alter them to make them more accurate than stock or on some mods it's input into M1, M2 etc.
TFR is more accurate as it uses multiple data points between lowest & highest temp & creates a curved line. These are used in DNA .csv profiles.

i know what it is I just didn't know what the figures were

does the resistance get higher of lower if the coils are spaced? from what you said earlier I would need about 14/15 wraps to do dual coil at 0.3

what if I did 26 gauge?

No difference to resistance spaced or touching. Just eliminates hotspots.
22awg is not what I would use for TC, especially dual coil. Lot of metal to heat up & could throw TC/resistance all over the place. Single coil 7 wraps may work, but at least you've got Replay/power mode to fall back on. I used to use 28awg for dual builds but no consistency made me ditch it for NiFe30.

if I've done steam engine right I'd need about 6 wraps at 28 awg ss316L to get a coil to be 0.321

Sounds right for dual coil. I used 7/8 wraps from memory & when it worked was great

Seems like a silly question but when I get the spool I take it I just snip of a section of it to put on the jig do I?
