Thanks for posting my link DK
Since then I've slightly modified my thinking about this and would add that now I only recommend getting anything heavy shipped using a custom crate, forklifted and shipped via freight, truck etc ..... The packing showcase at that link would truthfully not protect 100% against a really long fall such as from 6 feet up. This is more for bracing and protecting the item from stuff falling onto it and placing that on a pallet. There really needs to be more "GIVE" in the packing, for shipping it via the typical way where a lot of conveyor belts and throwing and falling goes on. The item, in this case the heavy recorder, when dropped in its box, cannot just hit a brick wall. The packaging needs to give way and sag for a while before stopping the item in its tracks. That way it'll absorb the shock, the packing that is. If a recorder is packed in styrofoam only then not a lot of GIVE happens. Enough to minimize damage but still not good enough. The packaging example, even less would be fine, is for shipping on a pallet and / or crate and not really via the standard route.
