32 Ga Kanthal

  • Nichrome sez - 165 w from 8.5 feet.
  • Nichrome rho - 100 - 150 x 10-8
  • kANTHAL - 13.1 oHM/FT - [1]
  • Nichrome 60 - 10.55 ohm/ft - [2]
  • Power = IV = I2R = V2/R
  • Try 8' of Kanthal, should get about 120W at 120V. V=IR - I=~1A. Works. 8 feet used, wrapped around 2' of inner sleeve, used fence wire + wrap. 140 weight carbon fiber blanket for insulating base. Top is much hotter than base.

31 Ga Nichrome

  • Use 9' to get 1000F at 120C for 180W
