Did some work on the wall prototype today. I completed the wooden parts of the sill plate. The hempcrete will go on top of this. The work went pretty well. I first made a jig to help figure out the curves.
Then using the jig, and a 12" by 26" piece of hardboard representing a straight wall segment, I layed out a wall section with three posts on a piece of 3/4" plywood. Made a few mistakes but nothing major; the usual sort of thing when building a prototype. Tomorrow I'll add the truncated posts and the sill insulation, then build the form for the hempcrete, which will include a window opening. It's fun to be building at full scale, even it's only a prototype.
