I wish people shipping heavy items would learn how to do it. You can't just use loose foam, or worse, packing peanuts. Probably the best packaging I've received was a rackmount network switch. They wrapped it in plastic, then surrounded it with what looks like expanding foam. The result was a package that felt like a solid object from the outside and nothing could move. I'm not sure that trick would work with machines/parts though. For that you might be better off bolting it to wood, and building a wood box inside the cardboard box to support and protect it. Or maybe bolted to a pallet, build a box around it, and ship freight. That's what PM did with my lathe, and it came though fine.
