The MK-VII departs from all previous bracket designs by adopting a full triangulated space frame geometry. Using 1.5" square steel tube throughout, the frame achieves exceptional rigidity without the weight penalty of prior solid-plate designs. Stress testing underway. Early results are promising. The welder is optimistic, which is historically a bad sign.
The garage operates as primary fabrication space, materials storage, and occasional test range. As such, maintaining a workable temperature range is classified as mission-critical. Phase 1 covers smart thermostat integration, automated ventilation sequencing for welding operations, and task lighting on occupancy schedule. Phase 2 will address the fundamental question of whether a garage can ever truly be warm enough in January.
The MK-III jig solves the fundamental problem of every welding project: getting repeatable angles without layout work on every single piece. Fabricated from 1" square stock with a backing plate and adjustable fence, it produces cuts consistently within ±0.4mm. This is, by this lab's standards, extraordinary precision. Documentation of the MK-I and MK-II disasters available on request.
What began as a one-afternoon project exposed significant pre-existing structural anomalies in the primary habitat facility. Studs at non-standard spacing. Sheetrock of inconsistent thickness. A floor that, by all measurable data, is not actually flat. A level that disagreed with itself depending on orientation. The shelf is installed. It is level. The path to levelness required more problem-solving than the MK-V bracket. Lessons are documented.
