Hay all I am trying to build a Kiln (Heat treat oven) for my knife making so that I can temper my blades but I am no electrician and I need help figuring out how much resistance I need in the coil that will be heating the oven I'm wondering if I need to run 2 separate coils connected together in the back of the oven or if just one stretched out would be the right way to go I made the oven long so I could do small swords if I knew what resistance I needed it would help me a tun I'm going to be running it on 220v the oven inner chamber dimensions are 31,1/2 inches deep 8,1/2 inches wide and 6,1/2 inches tall the coil slot is 11 feet long the inner diameter of the coil I made is 9.5mm I wrapped the wire around a 3/8in metal rod and the kanthal wire is
- 16 AWG, Average wire diameter: 0.0508 in. (1.29032 mm), 0.324 Ohms/ft at 68°F
- ALLOY: Kanthal A-1 (22% Cr, 5.8% Al, Fe balance). Rated for temperatures up to 1400°C (2550°F).
