I got this basic concept from another website, www.cindydrozda.com. So basically I took some leftover pieces of wire closet shelving, made a standing shelf, then took some scrap plywood and wrapped it, bought 4×8 sheet of insulating foam and lined the inside. then bought a $15 single pole baseboard heater thermostat and wired it to a ceramic attic light fixture I had. put a 100 watt bulb in it and closed it up. drilled air holes at top and bottom to allow airflow. it works like a convection food dehydrator. supposedly it cuts drying time for green blanks down to 1/3 of normal time. If it doesn’t work, I can always use it as a warming cabinet for my glues and finishes!
02/27/13 UPDATE: After watching this cabinet for 2 days, i realized the 100 watt bulb wasn’t doing the trick. the light was never going off, just on constantly. temp in the box was barely hitting 68. so, I bought a 125 watt heat lamp from big blue and tried again. the temp is considerably higher, running about 75 now, which is about where i want it. In order to facilitate more air movement, I am mounting two scrap 5” PC cooling fans wired to a wall wart. one for intake, one for exhaust. hopefully the additional air movement will provide me with the desired results. Pics to be posted after everything is mounted.
