Things change.
In July I'm bringing home a flathead truck radiator as my checked luggage on United from LAX to Dulles. I'll be in LA for a family trip. I will have to pay a small upcharge based on weight which I calculated at 65 pounds (it fits the size limits) but it's so much less than shipping another way. A trip to a home center to purchase a 4'x8' sheet of insulation foam to cut pieces to protect it and create a solid block, then a heavy layer of cardboard and lots of tape. Couldn't do this with a flathead block, but it's the kind of thing I do to keep the hobby juices flowing.
