If you happen to have one of those laser type thermometers, could you measure the surface temp of the collar, and the surface temp of the side of the chest freezer? If not, can you feel a temperature difference on the wood versus the side of the chest freezer?
I suspect it isn't a big issue since I haven't seen any discussion on it in the past. I haven't built the collar yet, so I want to do a little homework first.
