Re: How to build wood tower ?

Besides arches, the triangle is a very strong shape. Once the apexes are pinnned or glued, the wood has to buckle before the shape distorts. Making support beams out of a lot of little wood triangles leads to a very strong shape, i.e., roof trusses, with the load distributed over more material.

The compression strength can be further increased with lamination. This means plywood and maybe I-beams. These will increase compression strength for the same amount of wood. Try to combine plywood, I-beams and triangles.
