Trust me, I've built a few things that sounded good, worked in theory, and actually worked great in practice. For a while. Fortunately those instances have been rare. Sort of. Last one was a lumber cart. Looked great though
I forgot about the multiplying forces! My dad had convinced me that the screws would hold, but I don't think he did the math I'm going to have to talk to him about it again... I have a couple of ideas for strengthening it, so I guess stay tuned!
