Surface flatness verification kit
Reversal-capable straightedge, contact indicator/feeler and supported datum comparison for bench surfaces; discovery hypothesis, capability and compatibility unreviewed.
Discovered · unresearchedClosure: OpenInventory incomplete
Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.
Parts and Tools needed
No researched inventory yet. This is an unexpanded frontier; an empty list does not mean the item can be obtained directly from nature.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
