Making outline
- Melt: Melt a controlled batch of refined copper. Check: Usable melt without unwanted inclusions.
- Cast stock: Cast a sound bar or billet in a suitable mould. Check: No serious porosity or cracking.
- Work to rod: Forge or roll into rod; soften as needed between reductions. Check: Straight, consistent feedstock for drawing.
- Inspect & clean: Remove surface scale and reject defective stock. Check: Stock passes subsequent trial drawing.
What remains unresolved
- Casting shape is easier than controlling purity and internal defects.
- Exact grades, quantities, operating parameters, tolerances and complete making dependencies are not finalized.
