That's great advice. The brutality that sometimes occurs in shipping is something to behold.
Proper packing with strict adherence to carrier requirements is absolutely essential if an insurance claim has to be filed.
I bought an MX-5050 8-track a few years ago that was damaged in shipping via Fedex. The machine was packed in a double-wall box protected with styrofoam blocking and paper matting. This box was inside another single-wall outer box with three inches space between them filled with paper matting. When I got it, both boxes had been speared with something (looked like it must have been a 2-inch pipe). The side panel was split, the ventilation plate was buckled, screws were sheared, the brake assembly was bent, etc. All in all around $2300 damage. The Otari tech said he was impressed with the force it took to do this. Fedex eventually paid, but they fought the claim for months. Fortunately the packing met their guidelines.
