I then started building the ale chamber
I drilled a hole in the bottom of the lager chamber.
I stuck a drier vent in the hole.
Then I stuck an AC fan on the inside to blow cold air out.
I put a drier hose at the top of the ale chamber.
Building the floor to the ale chamber
This was the best way I found to mount the probe for the lager chamber. I drilled a hole in the top of a whitelabs yeast vial, filled it with water and poked the thermistor from the Ranco down through the top.
And again the final chamber. I may add taps to this at some point. The lager chamber is at 35F and the ale at 68. I went back and use 1/8" foam to cover the entire inside and the floor. Turns out wood is a good conductor of heat. I will probably add more insulation come summertime. Right now it turns on for about 10 minutes every 3 hours.
