STL197: Clean Miters That Are Actually Strong

Question 1:  From Elijah: I’m planning on building a floating media cabinet out of 5/4 cherry. The basic idea of the cabinet is an open box that looks like you can look through to the wall. However, it will actually have a false back made of 1/4” MDF painted the same color as the wall to hide all of the wires. For this project I like the clean look of miter joints, but I am worried that it will not be strong enough. The cabinet will be about 48 inches wide, 10 inches tall, and 14 inches deep. Do I need to reinforce the miters somehow or will glueing in the false back strengthening it sufficiently?

What is the best way to go about this? I am assuming some core 4-square stock is the starting point. These are going to be Krenov-type legs, so thinly laminating finished leg seems out of the question.   Segment: All-Time Favorite Tool  Mike: Holdfast Get a grip on your work Ben: CNC used as a pin router The Pin Router Anissa: Her marking gauges Shopmade Cutting Gauge Tool Test: Marking Gauges   Question 3: From Dave: What machinery can be bought vintage and what should be bought new(er_)? It seems as though this kind of discussion is all but exhausted when it comes to hand tools but I don't hear as much about the bigger purchases in the shop. For instance, not much has changed for drill presses, so an old and stout model seems like a chance to save some money. Meanwhile, it's clear that table saws have improved dramatically with regards to safety and dust collection, so if a SawStop is attainable, I should budget accordingly. But what are your thoughts about bandsaws, jointers, planers, lathes, and the like? Are some types of shop equipment less vulnerable to the risks of buying used?

I mitered the edges so the only visible end gain is at the top. I’m looking for painting suggestions. Some videos say to use Zinsser BIN, and others say to just use regular drywall type primer, then lightly sand before applying primary color. Do you have any suggestions that would steer me in the proper direction?
