  • Better Packaging for Transporting Submarines.

    After my fiasco with UPS and my X Craft, I've come to the conclusion that many of us, (myself included) pay little enough attention to packaging our models to move them around.

    My main concern is the movement of the model within the box, and especially the tail end, which, as we all know, is the delicate part.

    I thought about cutting foam to fit around the bow and stern, but is all seemed a PAI, and then I came up with this idea. I always prefer molding something, rather than machining etc. It seems to be so much easier.

    I took a plastic shoping bag and filled it with Great Stuff Foam. I simply squirted it into the bag and filled the bag with enough foam to fill the end of my box. Then I pushed bags into each end of the box, and pressed the model down into the foam, making sure the ends of the bag were folded over so no foam could get on the model.

    Once it's set up, pull the model out, take the plastic bag off, and then trim up the foam. You could do a second bag on the top of the model to completely encapsulate the ends. I made a saddle out of pink foam, just to prevent me pressing down the model too far.

    Alternatively, you could use Alumilite two part foam, which will set up within an hour. We carry this product in stock.

    I'm going to do all my models like this. Anyone else game?

    Isn't there a commercial packaging material like this available out on the market today? I was watching an episode on modern packaging on Modern Marvels on the History Channel. They showed a bag that contained expanding foam and an activating solution contained in a small inner bag. You squeeze the inner bag to pop the activator and shake the bag to mix the 2 together. You then place the item you're shipping inside a box and surround them with several activated bags which conform to the shape of the item ( and inside of the box) protecting it.

        Mike,
        I think you are having foam flashbacks from when I sent you the Darnell. That is how I packed it - using the expanding foam and shopping bags. I may have gone a bit crazy, but it did make it there in one piece.
        Peace,
        Tom
        If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

          1. At least $5 for each bag.
          2. Minimum size 8"x8"x8" and you can't split the pack.
          3. Minimum order case lot of 26 = $154

          Pondering the concept a little more, I think I can develop a process here to reduce the amount of expensive resin.

          Cut a base block from any foam that fits the bottom of the box and place it inside the plastic bag. Either mix up the Araldite foam and pour it on top of the block, or squirt Great Stuff foam on top of the block.
          Immediately place the bag and center the block into the bottom of the box. Set the model into the foam, making sure you don't get any foam on it. It might be wise to wrap the boat in Gladwrap to ensure it is kept safe.


          I'll give this a shot tomorrow.

ID:	66709The foam is a good idea but i would still use 3/4" plywood for the box.
                because of this^ and it is typical.

                  I'm using triple board cardboard. When it's finished, I soak the entire box in thinned epoxy. It becomes extremely strong, but I'm not suggesting shipping that alone via UPS. You need another box around this.

                  The major advantage of these cardboard boxes is that they are very light, and my foam idea is simply to stop them slopping around when taking the boat to the pond.

                      Lacquer thinner - not acetone.

                      Do it 50/50%

                        Why not make the transport box out of Coroplast. No need to waterproof it with epoxy.

                        Aren't you due for an election soon. Bet you could get some coroplast political signs for free then.

                          But how to glue the sheets together, that is the problem?

                            How about Sikaflex or equivalent mastic based glue?

                              Interlocking tabs, pop rivets, small nuts and bolts, zip ties, take your pick.
