38DD Mother of a Fermentation Chiller
After building a Son of a Fermentation Chiller and using it for a while.
I found the following problems:
· It would only hold one carboy
· The analog thermostat sucked
· It is a PIA to deal with the ice in deep narrow ice chambers
So I redesigned the controller first to use a digital remote sensing thermostat for under $25.
Then I redesigned the Son of a Fermentation Chiller to hold two 7½ gallon carboys
and two ½ gallon growlers for my blow off tubes.
removed and the top and front removed.
A good grade of carpenters wood glue
works better than Liquid Nails. I used Elmers
Stainable Wood Glue Interior/Exterior Use. It does take
a little while to dry so you have to tape the parts together
so they don’t move while the glue dries. The base is in 2 pieces and is edge glued to form one.
One brewer who built the 38DD
had better luck using a different glue. “Hey- thanks for the writeup on the
build. Very cool. One thing though- I think you should recommend a
different adhesive than the wood glue. For this type of foam, PL300
Foamboard adhesive works best. It comes in a caulk tube and is way better
than the wood glue. I started out using wood glue, and then ended up
pulling the foam apart and removing all of the semi-tacky glue. It was a
mess. But worth it. The PL300 is nice and tacky right away, so it
holds the pieces together well. Just a suggestion, but I think it would
be a good idea to change that small part of your instructions.
Thanks again for the build directions and calculators!”

I would think just about any fan would do.
I thought was slick. The lid acts as a
drip tray for the condensation.
Pictures from other Brewers who have built the 38DD
by Micah Stark. Looks like a fine piece
of furniture. Well done Micah!
For them that wanna know how Micah
did the Starkbier sign he made the template
in photoshop, printed it out in full scale at
kinkos and cut it out with his scroll saw.
Kevin Burns. It features a
slightly differen wood cover
arrangement. This is proof
that the plans are just a guide.
