That's a neat little fridge! You could make the door from 2 pieces of clear acrylic with an air gap (double insulated) to help with heat gain through the door. Also, one central hinge may not last too long , 2 smaller hinges or a piece of piano (continous) hinge. Every little bit of insulation helps. Great design & explanation!
A friend bought one of those drill sharpeners (after I told him not to waste his money) and some dead bits around for me to sharpen as he had no clue how to go about it. I could sharpen 10 by eye on my bench grinder in the time it took me to set up and grind / regrind/ regrind 1 on the useless sharpener. This jig you have shown is nifty in the way you can see an off-centre grind.I have used a scribed line at 59 degrees on the work rest of the bench grinder, just fill it with white chalk every now and then.
