I’m making this a blog reply because I want to include a picture. As you can see, the back wall is quite large and will be cut from 1/8″ MDF.See the hinge? I bought 2 that I ordered from Vertex Hinges. It’s made of brass, and I believe it is 4″ long. I could mount it to the inside of the interior wall. It would be sturdy and I think it’s feasible as long as I can mount it securely. It might take some beefing up with strips of wood to give me a base to work from.
I like your idea of magnets, too. I’m torn – but I would need more like industrial magnets or strip magnets to handle the weight of the MDF, I suppose. It would certainly work on smaller, lightweight panels and be easier than hinges.
This will take some mulling over and experimenting. Guess my first step would be to cut the thing out and go from there. I’ll keep you updated. Thanks, Sherrill!
