With the schematic of a final design in hand, this week we finally headed into the shop to start building. We kicked things off Monday with a shop tour and student demonstrations of cutting, grinding and welding metal. Wednesday and Friday we were aided by some rare Seattle Sunshine as we began to assemble our first two greenhouse boxes. Teams of students rotated into different positions to give people the chance to learn new skills.
We started by working out our system of assembling the sides of our frame. Several steps have to be completed to create one side frame: rough-cutting the parts, then cutting them to a final exact size and angle, doing a test fit, beveling edges in preparation for welding, welding, then grinding welds. We established a “master set” of parts to which we can compare pieces as we cut them. One team worked on putting together a jig which will allow us to build each side frame to the same specifications. By the end of the week, we had nearly completed two side frames to make one box, and had a good head start on the pieces for the next box.
Meanwhile, we continue to work out details of our design as we build, such as the final configuration of boxes on the building, box roof details, shelving details, polycarbonate attachment details, and box-to-building attachment details.
