Shipping CRT's
Does anyone out there have any methods for safe CRT shipping? I am thinking using a custom foam padded case may be the safest way to minimize possible damage. Something like the photo below except made for the tube(s)...
![]() The reason I ask is I had a 23ЛК1Б picture tube shipped to me and it was damaged in transit. The CRT was enclosed in a custom built wooden box and it came intact, but a tiny piece of something was loose on the inside and it caused the damage you see to the photo below to the phosphor face. The CRT was boxed face down (at least that's how it was marked) so the piece just sort of rattled around on the face. Maybe that damage was just a fluke, but I think if it was mostly horizontal it might be safer. What do you guys think?

Just a WAG here John, but if the tube had something loose inside of it large enough to cause that kind of damage to the phosphor, I'm guessing that either a) it had issues long before it was shipped, or b) it was knocked around enough in shipping to loosen the culprit up and cause the damage.
I've always just double or triple boxed them in cardboard boxes and held my breath. Packing peanuts and bubble wrap are your friends. There isn't much you can do to minimize shock. I've seen the equipment that most of the major shipping companies and postal services worldwide use; if a box can't survive a 6 to 12 foot drop onto a hard wooden surface, you probably shouldn't be shipping it period. |

I've seen several original CRT boxes where they were face up. I suspect for exactly this reason. They only used some cardboard cross bracing.

Was the loose object inside the CRT? If not there are ways of polishing external blemishes off of glass...
I've never mailed a CRT, but if I did I'd use the same packing method the factory original shipping containers did*. The original method stored it face down on styrofoam corner bracing with cardboard bracing around the neck....I'd add a crap ton of packing peanuts to that, get inch thick Styrofoam sheets to cover the box with, put that box in another that J-U-S-T fits over the styrofoam, then consider triple boxing with peanuts... *Have you seen one, if not I have one and IIRC pictures of it on one of my image hosting accounts. Packing on it's side is just asking for trouble....The neck is the thinnest part of the envelope and putting force on it from the rest of the tube is practically asking for it to snap. Perhaps you should make and test your own box for it, then mail it to the seller with instructions on how to re-pack it with the CRT.

This is just my personal opinion, but I ll take bubble wrap any day over packing peanuts. I find the packing peanuts can shift/settle a bit, but the bubble wrap does not and is more firm.
The bubble wrap in conjunction with pink or white Styrofoam sheets 1 to 2 inches thick from Home depot and double boxed. I have never had one broken. I would only trust the shipping to FedEx or Greyhound where possible. Correction, I did have one broken once coming to me but it was sent by UPS, and nothing would have saved it based on the shape of the box was in when I received it. |

Here's the basic concept that's worked for me 4 times to date, including a 21 rectangular CRT. It's basically the same method that manufactures used, plus some extra padding added around the bulb portion of the tube. You don't necessarily need to use soft foam, but you do want some significant thickness of shock absorbing material surrounding the face and sides of the CRT bulb(the heavy end). The key is to only pack around the bulb portion of the CRT, leaving the neck to float in the free space inside the cardboard gridwork. Ideally you want some compression between the front of the CRT and the rear cardboard grid that cradles the back funnel of the CRT. Absolutely DO NOT substitute foam peanuts for the packing material, as they will shift.

The only one I sold and shipped I put styrofoam on the bottom of box, put 2 plastic bags around the crt, set the crt inside of box, sprayed can spray foam inside up to where the neck started. Let it harden and double box with nothing inside touching the neck. I read how to do this on this site somewhere. Worked good. When they get it they have to break the foam away. This was a smaller crt and it might be hard to do on larger ones.

John,
Follow Kevin Kuehn's recommendations. Basically this is exactly the way the 15GP22 box that you picked up at ETF is constructed. With the exception that I used a tri-wall cardboard with a round hole in it over the funnel to support the egg crate above it. Folsom and I shipped 2 15G's to France via FedEx air and the tubes arrived without any damage. I would also use Grayhound whenever possible. All Greyhound packages are individually handled like the passengers baggage and ride in the luggage compartment under the bus. NIce soft air ride greyhound bus.

Thanks for the thoughts everyone. The box that was constructed for the 23ЛК1Б got it here in one piece, aside from the damage to the phosphor. The loose piece inside the tube is minuscule, I can't believe it caused the damage it did. I'm afraid to use any method of shipping on a replacement that puts the tube face down. This tube isn't tremendously easy to find "around these neck of the woods" so I'd rather not make it "3rd time's a charm" if I can avoid it. I don't know how to shop it face up as the weight distribution would naturally make the box want to go face down. I think if I can get foam molded to the shape of the tube and put two in a box facing opposite directions then the box would naturally sit on its side.

Styrofoam transfers the shock, so is really of little value. Use foam rubber taped around the entire CRT and then box it. This will decelerate any impact gently.

We have shipped dozens of tubes from the museum, without damage to any of them.
I think it is important to provide some sort of protection for the neck that doesn't allow packing material to contact the neck, as Kevin's post shows. Then, double box the tube. |

I'd avoid UPS
just on account of the volume they handle. Have you ever seen the action at one of their shipping centers? They are throwing that stuff on the truck as fast as they can. Nothing gets special treatment. All their loaders are part timers too. And they know there is no future with the company.
I'd go with FedEx, DHL or somebody like that.

Agreed, avoid UPS. I've had over a dozen shipped to me successfully. The one or two that were broken were sent using UPS
Many in original boxes which were just like Kevin shopped. You don't need tons of packing foam or peanuts.

Looking at Johns damaged CRT it appears to have been subjected to extreme vibration, possibly the result of many shaker sorting conveyors. Unfortunately the mass of a heavy plywood container may have contributed to that situation. One can only conclude that the CRT was not adequately shock mounted inside the shipping container. Also, there is no guarantee that a shipping container will stay in any preferred orientation during shipment, regardless of the package's warning labels, but there's a natural tendency for it to remain heavy side down.

Agreed! This is why I need to figure out a method to keep the container on its side. This one was shipped via a direct flight from Moscow to Houston, then trucked to Columbus, and then to Pittsburgh. A replacement can be shipped via more traditional methods (FedEx, etc...) because its dimensions and weight will be far less than the last shipment (which included the entire television).
