One of the most challenging aspects of homebrewing is temperature control. There are many DIY ways to control fermentation temperature, but using a chest freezer with a temperature control themostat is really the best. Once this system is running, space becomes the limiting factor. I’ve had this chest freezer for over a year, but finally expanded it to hold 6 kegs. I really can’t wait to start my lager brew days! A billion thanks to my retired father for assembling such an awesome expansion of the freezer. Here is what he did, in his own words.

Once the wood is thoroughly dried, assemble the frame and be sure it fits properly on the freezer.
To attach the spacer to the freezer, buy a roll of industrial grade velcro. The freezer door must be disconnected by this time. This material is also extremely sticky. This material is attached to the freezer side as well as to the bottom of the spacer. Again, I advise doing a dry run with the velcro before final assembly. Place the velcro on the freezer first, and then after it is placed on the bottom of the spacer, carefully drop in place a press down for a few seconds. That’s it. The spacer is firmly attached. Place the freezer door on top of the spacer and be sure it is alined. Make sure the hinge is flush to the wood, pre-drill the holes and attach with 1″ #8 pan head screws, or larger or smaller if necessary. Drill any holes for the tubing to be used from the outside toward the inside. Use a thin paint brush to coat the inside of the hole just drilled with spar varnish. The spacer is now complete and ready for use.
