DIY wood drying kiln

There’s a weird nook in my basement drywall that I turned into a wood drying kiln. I lined the little box with thermal insulation and hung a 75 watt bulb. The kiln stays roughly 90 degrees. I ordered a little solar fan, so I am hoping it facilitates the drying process. I need to do some tweaking with this — Maybe it’s too hot or a I shouldn’t have scraped off the wax from the bowl blanks but a bunch of the birch blocks cracked badly. That said, it’s working remarkably well otherwise. The Maple started at 35% moisture content and was down to 10% in two weeks.
