I've dabbled in woodworking for more than 40 years. I've made many, many things that turned out really nice in my opinion, and even some others.
That said, I probably have a little better idea than your "average Joe" of the degree of difficulty involved in such a project. These technical challenges are GREATLY exaggerated if you don't have the proper tools.
There is a LOT of time, sweat, and sheer craftsmanship that goes into such a piece of art.
I'd love to own something similar, but unless I hit the lottery, I can't justify that kind of outlay for what I consider a luxury item. It is NOT a safe.
