The inside got painted and the outside was stained and finished. This is after the first pass with a satin finish.
The "skeleton" is 2x4's and then skinned in oak plywood. It's overbuilt to the point where you could probably sit a small car on top of it but I'd prefer it to be too strong. I use oak wood veneer tape to hide ugly plywood edges. It stains just like wood and easy to use.
This cabinet is heavy. A quick, cheap, homemade furniture dolly helps move it around.
I made a jig to drill evenly spaced holes so that shelves are adjustable in height.
When I get my light bulbs in, I'll get some pictures of the construction on the hood. There are a few things I'd do differently.
