This ones heading to China....
I tapped the loose headset parts together then tapped it directly to the top tube. There's open air in that area of the box so its no big deal for it to be out in the open like that.
The fork legs are on each side of the seattube. I used an old axle and quick release in the rear dropouts. The seatpost is taped to the seat stays.
At the end of the box by the dropouts I inserted a bunch of cardboard. There's something like 6 layers at that end!!! The headtube actually rests on the bottom of the box. I have it wrapped in 2 layers of pipe insulation with 2 layers of cardborad tucked in front of and underneath it. Adding in the box thats 4 layers of cardboard.
Before anyone asks its a 1986 Schwinn Peloton built with Colombus SL/P tubing. Shipping was $95 plus $10 for my time and materials.
