the closing of tolerances.

Refinement is the most intellectually demanding phase of the entire process. Here, we move beyond standard measurements into the realm of tactile feel.

Using small, custom-forged steel scrapers, the maker micro-shaves contact points and bearing faces, removing layers measured in microns. This slow scraping ensures that plates slide without play and shafts rotate without runout. Polishing paste is applied to pivots, turning them until they achieve a mirror finish that minimizes wear. It is a slow, quiet craft that cannot be automated, converting raw assembled parts into an instrument of ultimate precision.
