You should assess very carefully all the hazards before you even consider starting. Just some general advice: - Making a structure is relatively easy it just takes some standard good practice and patience. - Think about getting some decent temperature sensing gear for the sake of safety and monitoring your part. - The hardest part - Choosing the heating element: What type of source you use; The cost of the source; Efficiency of source; How the thermostat behaves. AND MOST IMPORTANTLY The Safety of the source. - If a heat lamp isn't used then consider this: Most cheaper heating elements will come with thermostats however getting a constant temperature is very difficult as usually the air will get up to temperature then the thermostat clicks in and the heat levels will drop heavily to maybe 20 or 30% of the temp the thermostat kicked in at and then the timing of element warming up again may be inconsistent causing a quite odd curing pattern that will fluctuate a lot. - Consider the risk of the heating element over heating and any precautions in place (e.g. thermostat) - Think about fire safety. Heat resistant materials. Fire Retardant Materials. The environment your putting oven in. People who could be affected. - If it is placed flat on the floor. The large surface area will cause the floor to suck a lot of heat out of the oven. This wont't happen if it is put on casters or at least some batons.

Programmable electronic control, used 2 x heating elements with fan assist, went up to around 250 c quite easy and had vacuum inside. It even turned the vacuum pump off when the cycle had finished. The control did have a back up system to cut power if the power to the elements became locked on due to a malfunction. The basic structure was a steel box within a box with rockwool insulation and insulated doors, it worked a treat and speeded up production. I think it cost around £800/£1000 to make. Ran off a 3 pin plug and didn't use much electric as the elements were pulsed with power. I sold it to some guys in Leicestershire, I think they were. They made carbon gaming chairs. Any how it turned a 24hr cure into a 1~3 hour cure, well worth it if you need quick turn around. Edited 13 Years Ago by Ragece
