## Notes

- What a Lee Spring stock catalog covers (its own overview page): compression springs OD 0.025 to 1.937 in, free length 0.025 to 6 in, wire 0.004 to 0.177 in; extension springs OD 0.063 to 2.0 in, free length 0.250 to 10.0 in, wire 0.007 to 0.207 in; torsion springs OD 0.105 to 2.141 in, leg length 0.375 to 4.25 in. Lee states over 25,000 stock designs. Materials: music wire (plated or coated) and passivated 302 / 304 / 316 stainless; heavy-duty compression also in oil-tempered MB wire. The page states no rate range, so none is given.
- The rows below the ranges are individual stock parts read from Lee's product pages (they are samples across the range, not a catalog table): the rate, solid height and coil counts are the page's. Compression rate k = G d^4 / (8 D^3 n) is on the springs page. Extension free length is measured inside the end loops. Torsion torque is the maximum at the stated deflection; the page for LTML 100J 04 M lists no rate.
- The LC 026BC 08 S page prints wire 0.03 in in its table and 0.026 in in the description; the part number's 026 and the description are used. LC 026EE 10 S: the page's 'ID' column is the hole it works in, so ID is left out for every row.
- Lee's printed catalog sections (extension and torsion PDFs) were also tried; their text came back scrambled across columns, so no row from them is used.
- No files: a spring's outline is a coil of wire whose pitch, end shape and hooks the pages do not print as numbers; the existing springs page has the envelope models.
