Making outline

Blank annular copper gaskets using separately made steel punch/die and manual actuation, machine/deburr selected cut edges, then independently compare sealing geometry
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.
