I bought a 12" x 6" x .5" piece of aluminum from mcmasters since aluminum is cheaper than steel in that size from them. Anyway, it shows up today and I have it sitting on the kitchen counter where I opened the shipping box.
A bit later I reach into the fridge to get the pork loin I pulled from the freezer earlier. It was a bit late in the day so it was still frozen.
Thinking about how good a thermal conductor aluminum is, I laid the loin on the chunk of aluminum. Darn, that works pretty good. For a second check, I got a fully frozen loin and put it on the plate. Thawed about 1/4" in less than a hour.
The aluminum will not be staying in the kitchen since it is destined to be a mounting plate for my Lee Loadmaster so I can mount it to my Bridgeport table and use that for a bench. The machine room is the only part of my garage that is heated. I'll also drill and tap bolt patterns for my Lyman Turret and Lyman LubeSizer.
