Here i want show how correctly need to do assembly a sections.
Here you can see plywood on which we will be all to do, this plywood will be like a level, where must be all sections, first we must mark dimensions where will be our sections, for exemple our sections will be after every 10cm.
Now we must install all our sections, center of shape, must be at center our mark, at center line.
But before this, you must take best variant for you.
Here you can see, I installed all sections wrong. Here I installed our sections before line. This is not deadly, but with this is more work, to fix this, need cut or whittle down angle of plywood.
Here we can see better variant where i install sections after line.
Here we need only cut a styrofoam on shape, and nothing not will interfere with to us.
