Anyone cruising the net of Cozy builder sites can see some great looking epoxy hot boxes. While I don't have extensive wood working skills I decided to build my own box like everyone else.
We went to the local Aircraft Parts Store/Depot/builders supply center to look for wood and parts to build the the epoxy hot box. I don't know if it's because we live in the high mountain desert and we're just far away from where the lumber is produced but OUCH! Figuring out the final bill for the epoxy hot box makes it look like I may need to shave off a chapter from my first parts order. 
We wondered around the store for awhile and then stumbled upon this cabinet for sale for $49.99.
This looked like a viable solution without setting me back a Chapter in my order. Next we went back to the isle that holds all of the foam insulation, some wire, bulb socket; this can work! 
Putting the cabinet together wasn't difficult so I strarted stuffing it with foam. 2 inch foam on the bottom and top. I put 1" foam on the sides. Since I had already mounted the light (not thinking about how far the 2" foam came out form the side wall, I figured 1" foam would be perfect! 
I had to go to a different hardware store to pick up a thermostat that could handle AC. Most thermostats at the local Aircraft Supply store have DC thermostats. Naturally the DC thermostats do everything but fly a plane and are priced accordingly. However you can't wired them directly up to an AC line cord. I picked up this AC thermostat for $15.00. I mounted it on the side wall and wired it in.
Now it was time to install the shelf. With all that foam eveywhere I had to have some way for the heat to circulate in the epoxy cabinet. Time to pull out the drill. Jan drilled the holes in the shelf and this is what it looked like.
The front doors were hollow but it looked like I could slide in some 1" foam. - Yes it works!
Time to start putting it together!
Ok, this cabinet isn't exactly the marvel of modern engineering accuracy! 
The back has gaps in it where the center piece mets up with the back sides.
Here's a close up of the gaps.
Time to RTV all the holes!
Here's the end result. We'll see how well it works through the coming winter!
