Req'd items: ice chest, plastic hardware cloth, 20oz water bottles, flexwatt, thermostat, silicone caulk, duct tape.
1. Line the bottom of the cooler with flexwatt, and drill a hole for the power cord and thermostat probe to pass thru, seal opening with silicone caulk.
2. Cut the plastic hardware cloth to size, and cover the entire bottom to protect the heat tape.
3. Line the hardware cloth with filled water bottles (stored heat energy) laid on their side. Tape the thermostat probe securely to a bottle near the center of the cooler.
4. Place another layer of hardware cloth on top of the bottles. This surface is the new floor of the incubator. Now you can put your eggs in rubbermaids and place them here.
Hope that helps.
