Good Kilns has applied it's kiln manufacturing skills to produce a new and affordable way for the knife maker to heat-treat and temper almost any knife blades. Chamber dimensions are 10-3/4" (D) x 8-3/4" (W) x 4-1/2" (H). The kiln operates with an infinite switch and a digital readout pyrometer. Maximum temperature is 2000° F. Electrical requirements: 120V 13 Amp 1560 Watts. This easy to use oven, end opens for easy loading and unloading. Kiln comes with stand and two extra firebrick, ready to slot, one--one for the heat treating process, and one for cooling the blade after it is removed from the oven. Truck shipped.
