Making outline

Assemble manually ram-fed heated slit extrusion head, mechanically driven aligned cooling/draw rolls and stretching/take-up stages; compare actual film feed/thermal/tension/thickness using separate commissioning material.
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.
