Making outline

Manually machine selected ferrous stock into matched annular split cavity halves with guides, physical closure stops, vents/parting relief and accessible ejection edge, finish contact surfaces and compare independent geometry with separate uncured trial charge
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.
