I was fortunate to be allowed to build one of the models for the Earth Day event taking place in Houston in a couple weeks. I received a box full of books today so I began my build of a 37” tall Saturn 1B. From the pile of paper strips I still have it is going to take less then one book to build this model. Depending on what I use for centering rings I may need a couple extra covers which I have plenty of.
Basically I will be making all the parts seen in the image of the old Estes Saturn 1B layout page out of book. The second image shows the book I am using and a few of the mandrels I will use to wrap the paper around.
The build starts by making a simple jig to cut all of the pages to the same width. They didn’t come out perfect but they were close enough. The first layer of paper was made up of strips of paper taped together. This long strip gets spiral wound around a suitable tube to obtain the correct tube diameter. It is simply taped on each end to hold it in place Since this is a Sport Scale model the tubes may or may not be the exact sizes needed but their close enough. Next comes the 3M spraying of the first layer of strips. The first strip is the hardest since it has glue and the edges need to line up as the spiral layer is made. The rest of the pieces go on easy since they have an edge to follow. I used four layers of paper, each spiral going in opposite directions for the eight tubes used on the first stage. The longer tube seen in the image is around eight or so layers. This longer tube will be the main tube that everything gets connected to and will also serve as the motor mount. The large four inch tube seen is the tube all the fins will connect to. It is cut to the correct length in the image with all the rolled tubes. I found it very frustrating to layer the paper around this large tube; since it was almost impossible to get the spiral seem to line up so I stopped trying. Hopefully tomorrow night I will get the rest of the tubes needed for the build so I can then layout the needed centering rings.
