It really isn't difficult or expensive=2C Will.I used polystyrene sheets (4
of 4x8') to make the oven against a wall. That takes maybe an hour=2C and
you can re-use the sheets to insulate your house.Put in a fan to circulate
the air=2C a 3kw fan heater=2C and one or two of the cheap 'outdoor' thermo
meters=2C where you drop the probes through one or two holes in the top. Wi
th the oven empty=2Cturn it all on and play with the settings on the heater
until the temperature stabilizes where you want it. Make sure you put some
kind of baffle in front of the heater so there is no hot spot. Beforehand
you also need to modify the heater to bypass the thermal safety cutout.
