Making outline

Cold shape and hand scrape shaft/support interfaces, fit plain bearings and mechanically retained wheel flanges, then verify independent rotation 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.
