Incubator parts

updated 20190801 added a 40mm fan mount

well here is the final parts for the incubator
the light mount , fan mount , thermostat, and also an egg turner/rocker .
The fan gets power all the time to keep the air flow constant it needs to blow a cross the light then to the thermostat this is called a forced air system and a more stable temperature. keeps the temperature +-3 degrees F.
fan is out of a computer and I found one with a speed control and set it to a slower speed

I looked at instructions on line some use the same thermostat it's made for a water heater cost less than $10 and covers the temp of 98-100deg f. with a 35w light bulb
