I picked up a cheap fridge for $10 on the weekend, I striped out the fridge gear at the top and left in the twin fans. I'm not much of an electrician so I got a thermostat that the crockpot plugs into.
I have drilled a hole for the thermostat sensor and for the plug on the crock pot, I have not purchased any vents for the top of the fridge and the door seal is leaking quite badly, I put the crock pot on today to try things out and it got to 110 and 66rh - the temp was still slowly increasing and I think if I fix the door seal it should get to 120 and achieve a slightly better rh
I also put in some leaf to check for size and to see how much air movement there was. Note I have removed the leaf for now and shut the kiln down till I can do some more work on it.
I like the idea of filling the water outside of the kiln and siphoning it into the crock pot so I want to include that.
Some quick pics
