Is this a kiln? A dehumidifier? Will this dry rough turned green bowls? Remains to be seen but…
This build is an amalgam of numerous comments, plans, articles, et cetera. Thank you, whoever you are. I read what I could, wherever I came across it and then just plain old went with it. Budget-style.
The cabinet is wood but it’s not my handy work. $15 off of craiglist. Yeah, I know – cut me a break. Mostly, I didn’t want to build a dedicated structure from scratch with very specific holes carved into it and then have this whole “experiment” not work.
The cabinet is 38” tall and 19” wide and mostly solid hardwood. It came from an elementary school. It has a false bottom (I guess you’d call it) which is great as a place to stash the wiring and whatnot without taking away from the useable cabinet space.
Heat rises so I put a 5 or 6” diameter shop light (with a 60 watt bulb) down in the bottom. Surface mounted by using the aforementioned false bottom. I lopped the lamps plug off and wired it through a switch. The other switch controls the fans. These are 12v DC computer fans. I got 5 of them today for a whopping $2. They’re not for intake of exhaust—- just circulation. I jigsawed two 4” holes in the shelf and mounted two fans in opposing airflow directions. I perforated the shelf with a lot of 3/8” holes as well.
I wired my 2 fans to a DC converter that came out of my stash of old electronic junk. It was probably from a phone or a USB hub or something. The fans are 12V and the converter output is 7.5. It was the best I could do and no regrets – the fan speed seems fine. Just a light breeze.
I still need to put a vent up top—- I’ll do it tomorrow. Gotta give the moisture an exit. Also, I plan on keeping an eye out for shelves. I’m thinking old oven racks or something like a metal grill. Figure if I find them I can always trim them to size with my grinder.
Temperature was a steady 78 degrees up top and 80 down next to the bulb. Good air circulation…..
Any initial input or observations? Appreciated.
If anyone’s interested, I’ll give an update on if and how this works.
