Making my DIY heat treat kiln I started this build back in summer 2016 by buying all the necessary parts for the kiln: Close to finish Bill of materials: Heating element (wire coil, 80cm long, 5mm thick, rated 3.500W) PID Controller: Rex C100 + 1.250C K-type thermocouple Solid State Relay (SSR, 25Amp) Aluminum heat sink for SSR Old PC fan and box 1.200C for the top, bottom and the door of the kiln, theese bricks will not touch the heating element 1.500C for the walls, theese will incorporate the heating wire Some angle iron (40x40x2mm) Door hinges Basic layout of DIY heat treat kiln Basic layout I started assembling the core of the kiln.
