(Macro View) Foil Profiling Machine — Technic Experiments Shaping a profile… mechanically. Seen up close. This LEGO Technic experiment showcases a foil profiling machine, filmed with macro close-ups to reveal how every linkage, pivot, and contact point works together. The mechanism converts rotation into smooth, repeatable curves — no CNC, no software, just precise mechanical guidance. Macro view exposes what’s usually hidden: micro-movements, tolerances, and real contact between parts. Pure mec
