Curves and Beams
The half Satellite Dish has curves on two planes, horizontal and vertical. One of those curves needed to be followed through the upper body, working extremities of the house (the kitchen and loft) to the torso (the covered deck). My nephew, David Petersen is a gifted architect. I must credit David with cool treehouse ideas to replicate the Dish curve by fabricating curved ”glue-lam” beams. I built a large jig. It is a tool for bending and forming the trusses.
I sliced 2x4 boards into thin strips. Then clamped, screwed and glued them into the curved jig. The finished beams will eventually support the curved roof that shelters the deck. Each beam rises two feet from its ends, giving the space volume. Ten feet at the apex from the floor. These beams are like strong ribs housing the lungs of the house. They will offer amazing breathing space in the treetops. Adding a horizontal beam ties the ends together and keeps the truss in tension like a bow. The vertical posts in the center give it additional strength.
