In mounting a pyrometer, the vent holes in the back cover can be used to pass the thermocouples
through to the back firebrick and into the oven chamber. Mount the pyrometer on top the oven, and a
silicone controlled power rectifier of the proper wattage can be used with this oven. By controlling the
input of current, you can achieve an infinite range of heat adjustment over the range of the 1000-watt
model.
Leftover firebrick pieces can be cut into slices 2 inch thick and used to set your tools on.
