The multipurpose surf shaper stand

Here it comes! This is my very first time I will cut a piece of wood with the intention of using it for something else than poking dead animals or throwing it as far as I can....
I am from France and I was raised with the metric system, here, in USA you have this weird measure: inch, foot, yard, 1/2, 1/8, 1/32!! of inch well it is a nightmare for me! It is not that it is hard to go along with but having to approximate the quantity of wood needed I am always waaaayy off! For example, concerning the balsa, I think I will be able to make a second small surfboard for my 3 years old daughter...
Never mind, it is, I guess, better to have a “little” more than being stop because of supply shortage.
So to start with the stand here is what it should look like:

If I have the time, I will make an Ikea like type of plan of all the constructions.
Above the 2 feet of the stand, I will be able to change from the shaper kind of tip to the glassing kind of type tip. And on the “shaper tip” I should be able to put the rocker table.
Almost all the pieces are cut, I have started the assembly and I will post some pictures of the finishing product. To have the different extension attached on the feet I will use big screws and bolts, this will help me to reduce the cluttering of the patio...
