One of the more technically demanding parts of the refurbishment involved rebuilding sections of the machine’s PVC piping infrastructure. The machine had originally been manufactured using imperial measurements, which created a major maintenance problem. Many of the fittings and dimensions are not readily available, making future repairs unreliable and unnecessarily complicated. To solve this, I redesigned the affected sections of the system around metric specifications. This involved carefully measuring and reverse-engineering the original assemblies, redesigning transition points, and fabricating replacement pipework that preserved the machine’s required flow characteristics while allowing the use of standardized metric components going forward.
