No luck finding a local kiln so I have decided to build a dehumidifier kiln that will reside in my basement shop. In essence, it will be a 2x2x8 box of 1/2 inch osb board with a fan on one end and the dehumidifier on the other. Question about heat source: will a small ceramic heater be sufficient? I also will get a thermostat device to control the temperature. What temp should I shoot for during initial drying (want to kill any remaining critters). I want to avoid checking and will seal the ends.

As always, your good counsel is appreciated!

This might help...

Interesting points on "casehardening" if the kiln is run for too long of
a straight stretch. That topic is also covered here, with diagrams:
