Making outline

Assemble separate ferrous lever and plain pivot in reaction yoke with calibrated hanging working masses and guided thrust shoe; compare arm geometry and mass-to-force response independently
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Manufacture, quantities, suitability and complete inventory remain unreviewed.
Current memory-first method needs source and compatibility review.
