Can we consider our white glue + alcohol waterproof coating an effective choice to protect our alternative models? To what limit can this protective coating protect our models from the moisture, even if they are made from paper, cardboard and white glue? Trying to answer such a question, I rune a water resistance test with a little boat made from cardboard, paper and white glue. This little ship could live for a time period of 25 hours sailing on pure water. The boat carried some weight and don't wrecked. Since the boat was propositally made with several...

We may in general be worried about our own health security, but many times we don't know at all what are the accident risks around us, nor witch security measures will really protect us from hazardows situations. Moreover, some commonly used materials will effectivelly compromise our health in a long term manner, in a way we will not perceive until the damage is irreversible... What are these risks all about? How can we avoid them, and how to proceed in emmergency situations? This technical paper aims to partially answer these questions by providing the...

When you start the construction of a new model, probably you will not consider the future necessity of repairs and/or restoring it from time. Consider such a possibility, specially when you project your model's structure or choose the materials to employ in its construction, may be useful to avoid future problems. That paper tries to discuss some material and structure choice possibilities, as son as some difficulties and problems you can find when using some conventional techniques...

To cut and carve discs, cones and cylinders of massive materials, we need to use the correct techniques and tools, whem we try to achieve the best possible results in our modeling work. The default tool for this work is the mechanical lathe that is a stable and secure platform if correctly used. This tool can help you with several modeling tasks, but it’s very expensive! This paper discus some alternative ways to get the advantages of the mechanical lathe, without the need to buy one. There are several tools we can improvise to achieve this objective. Each of these alternative tools …
