I had built an incubator out of an old Pepsi cooler initially ( works great ) but I wanted something a little more user friendly, especially at candling time. I had trouble reaching back in between the trays to get hold of the eggs in order to candle them and the last thing I wanted was to ever drop one. I also noticed the more turners and eggs I added the more the air flow was blocked. I had pondered adding another fan in the bottom but that still wasn't going to ease my candling dilemma. I have two side by side turners now rather than stacking the trays with very easy access to them from above. I will install a 225 watt incukit that I'll be taking out of my old incubator. It's not the cheapest build but as this will be in the home I wanted something that was also pleasing to look at. The heater and fan will be mounted center if the middle facer this will blow heated air in all directions down and drawn back up to the center in a continuous cycle. I plan on using very thick plexi for the doors the 225 watt incukit should have no trouble controlling temp. I will be using Deans connectors on the turner wires and cutting the large plugs off this will allow me to simply unplug them to clean things out as needed. I will also be building a separate hatcher in order to do some staggered hatching and keep things rolling. I will post more pics of my progress as things come together. Hope this helps The original Pepsi Bator The cardboard mock-up Sides front and back pocket holes drilled ready for screws and glue Finally coming together Face frame glued and screwed Ready for some stain and sealer These are the small deans plugs I'll use on the turners i'll post more pics as I get closer to being finished. CAUTION always use the male connector on the turners and the female on the power source.
