On the grounds that there is no such thing as a stupid question, just one I don't know the answer to, but someone on this forum will.......
I have a small larder in the corner of the garage that is fine for deer from November to March.
I also have an old small chest freezer due to get scrapped (lid doesn't seal any more). So...can I use the unit from the freezer in the larder (adding insulation) to make a chiller? I guess what I'm really asking (as I can just try and see) is there any safety aspect in doing this?
