Chapter 1: The Head
Overview of the head
The head was the most involved (and probably the most exciting) section of the project. It touched on four crafts: woodworking, lightweight concreting, fiberglassing, and painting.
The head was made up of the following (in the order of making):
● The side-frames, out of 2" (50mm) thick wood.
● The inner support structure.
The inner support structure comprised the
cross-section and diagonal-section pieces
that were used to support the roof until the different applications (hypertufa, slurry) cured or set.
Most of this was then be removed.
The inner support structure from a looking down point of view was sort of like an eight-spoked asterisk ✳ .
● A layer of hypertufa (lightweight concrete) about 1¾" (45mm) thick.
● A thin skim of slurry (a paste-like mixture of cement and water).
● The side-covers, out of 3/16" (4mm) plywood.
● A thin cover (roof only) of fiberglass.
The first thing that I did after looking at a trillion photos, was to play around with design on paper.
I eventually came up with my final working drawings. My plans.
All of the plans can be accessed from the 'Table of Contents' page, but some will also be shown and referred to at appropriate stages throughout the course of these instructions.
