To simplify if you don't cut your own pieces, 1/8 square or 3/32 square for the major legs/posts, and 1/16 square or 1/8 x 1/16 for bracing.

I assume you're new to this.
You need to understand, there is no simple answer/no single "best thickness"
If you want to understand why, and what does, or may work, please take the time to read back through at least this year's design discussions - there are lots of different thoughts/combinations/possibilities; specific information from a number of people on what they have successfully used..... Look at the Image Gallery, too- both pictures and discussion/specific information.
Yes, a lot of folk are using 1/8th square, and 1/32nds square wood for the legs. I can tell you that anything over 1/8th is overkill. The real question on legs, is a) bass or balsa, b) what density (at a given size, there is a big variation in strength, depending on density), and c) what intervals you do bracing at (read the discussions this year on how column strength and buckling works). There is some specific information from some on densities used at various sizes
On bracing pieces, there is lots of discussion, lots of variations in approach and sizing- again, read.

That is still freakishly small. How in the world are you going to make your tower stand up under than much weight if the legs are that thin and brittle?
LKN wrote:Nope. Get your bracing, density, and precision right, you got a tower with 3/32 legs holding the 15kg. Read back through the forum this year and last year, you will see that it is very do-able.
TYG wrote:I'm not quite sure if there is a set answer for this either, but would it be better to use a denser but smaller piece of balsa wood for the cross bracing rather than a less dense but bigger? For example, a stick of balsa wood that weighs 1 gram that is 1/16"x1/16" versus a stick that weighs 1 gram that is 1/16"x1/8", both being the same length?
