Ok so Iv spent the last two days reading this whole post and now will ask a few questions in hopes that I can finish up my Mini fridge incubator:
1) Using light bulbs scare me after reading the horror stories so Ive taken apart a mini slow cooker. The heating element is a 120V 110W flex tape style element. I want to run this as my heat source as it gets REALLY hot really fast. I have a digital temp gun and I got readings of 220F in a minute. So how to mount this now is the question and is it better to wire this into a dimmer to regulate the heat and maybe try to set it at 99 and use a light bulb to take care of fluctuation or should I run the light bulb as stabilizing heat and run the heat strip at full tilt on a thermostat?
2) I was thinking the area at the bottom of the fridge is too small so I was thinking I would make a cut in the top corner of the shelf and a cut down both sides. Fold the steal flat on the bottom and the back Giving me a full 15". Any one ever tried that? I'm thinking area for thermal mass fans light bulb and thermostat. That would leave me the top portion for three egg turners and a hatchery.
3) I see everyone putting the heat source on the top. One of the genius of the world found out that hot air rises so why would you put the heat source on the top and not the bottom? With a fan drawing air down and a fan blowing across the heat source and the stat in the middle of the heat tape I would think this would be the most efficient.
Ill do a write up and pics when I'm done but if someone can answer these small hick ups Ill e back on my way.
As for an egg turner I'm going with the rotisserie turner. I have four trays I'm building and the eggs will lay on their sides and the eggs will roll front the back five times a day (that's how many settings I have on my timer). I will run the "meat skewer" down the center and use the meat prongs as my turning edge. This will push against the dowels and role them 3" each way for a total of a 6" role. this might not paint the best picture but I will post some pics as I get closer to the finish right now its all just a pile of pieces.
