Balsa wood is one of the unique materials

For example, it can be used in aircraft and boat industries for its lightweight and soft characteristics. As you may know that, balsa was used as the raw material of the Havilland Mosquito aircraft. It also can be used in boat industry actually, since the end-grain balsa sandwiched between fiberglass layers can provide strength and flexibility while it reduces weight to a minimum. It can be used to make the deck of boat and so forth.
What's more, it is mainly used for model building. It can be the selected material for the modle industry actually. Well, the balsa wood is graded according to how it is cut from log which may affect its properties. As we have introduced above, it can be classified into A, B and C grains. A grain has the best bending properties. And C grain offers stiffness. B is between A and C actually.
Balsa wood is one of the unique materials that is soft, lightweight and has high strength. It can be used to make models like model balsa wood towers for home use actually. There are different kinds of balsa grades actually, and you should choose if in accordance with your specific requirements and your budget ability. Frankly speaking, the balsa wood is very expensive. So, when choosing it, you are advised to be carefully.
In order to make your balsa wood tower, you may need some things like balsa wood sheet, pen, grid paper, ruler, marker, utility knife and wood glue. You should ensure that there is no any gap at joints sicne the gaps between pieces of wood will turn into weaknesses. And cleaner cuts and gluing can make a better hold actually. A few attempts will be required before your tower is perfect actually.
First of all, you should draw your expected balsa wood tower using the grid paper to give you a scale. You should design the exterior structure firstly. Start with the base of your structure, and make it wider to keep the center of gravity low. You should keep some reference photos or design pictures at hand if you are making a model of an existing tower. You should give the front, side and three-quarters-rotation view to the design you like actually.
Second, you should figure out how the forces will push or pull on the tower by using the diagram. You should try your best to imagine how it will stress the various parts of the tower actually.
