no previous part Part 1 of Bowl Drying Cabinet series Part 2: uh oh... »

I got this basic concept from another website, 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.

That’s an interesting idea. I just found Cindy’s PDF on her’s listed on Google and got to use Firefox 19’s new built in PDF viewer for the first time (no need for Acrobat Reader anymore!)—CD's Low-Tech Drying Kiln. She used a old refrigerator for her’s. I would imagine performance would vary considerably depending upon the room temperature and humidity.

Have your say...
