Original: Tjt263. Vector: AntiCompositeNumber. CC BY-SA 4.0, via Wikimedia Commons.

This is the credit recorded in Taxonomy.org §Sources and Attributions. The project author retrieved the SVG and confirmed the contributor identities at fetch time (2026-05-03).

Replaces the deficient thread-profiles.svg produced in v0.6.0 (since deleted). Embedded in F-03 BSPP section of the Taxonomy as the canonical 55° Whitworth profile illustration.

Project author downloaded the file from Wikimedia Commons, placed it under the project root, recorded the attribution. The illustration is embedded with caption and credited in Sources and Attributions. Slot is DONE.

Note: a side-by-side comparison with the 60° American profile (originally the F-03 Comparison ambition) is not provided by this single SVG, which shows only the 55° profile. The comparison aspect remains future research, possibly satisfied by an SVG composed locally from the Whitworth source plus a similarly-sourced Sellers profile, or by a render from the model library when it exists.

Original work created by Wikipedia user Brotherpete using open-source Paint.net. Public domain, via Wikimedia Commons.

Embedded in F-05 of the Taxonomy under the bonded seal washer entry. The diagram shows the construction clearly — outer hard annular ring, inner soft annular ring — with both labelled by callout in the source.

Project author selected this image from the Wikipedia Bonded seal article, confirmed its public-domain status, and placed it under the project root. The illustration is embedded with caption and credited in Sources and Attributions. Slot is DONE.

Iteration 0.7.0 listed the Wikipedia JIC fitting article (https://en.wikipedia.org/wiki/~JIC_fitting~) as the candidate source.

In iteration 0.8.0 the project author reviewed the article's available images and judged them unsuitable: the photographs do not isolate the cone-seat mechanism cleanly — they conflate it with adjacent-but-distinct mechanisms (flares, swivel ends, female-cone variants) such that the reader cannot extract from them a clear picture of the metal-to-metal cone-on-cone seal we want to teach.

Slot reopened. No file in the project root. The forwarding paragraph in Taxonomy.org §F-05 cone seat entry reflects the rejection and points to FutureResearch.org for the search of an alternative.

See FutureResearch.org entry I-03 alternative cone-seat illustration source. Candidate angles to explore:

• A purely-geometric cross-section drawing (CC-licensed, non-photographic) that shows the male and female cones mating with no other features.
• A project-author photograph of an isolated 60° cone-seat pair.
• An OpenSCAD-rendered orthographic section, deferred until the model library renders such a section.

Project author downloaded the original from Wikimedia Commons, downsampled to a reasonable size, and placed it as Doc/Illustrations/BSPPMaleStraightThread.png (now at the project root). The image is embedded in F-03 BSPP under the BSPP designation subsection of the Taxonomy and credited in Sources and Attributions. Slot is DONE.

Project author's own photograph. Three hose-clamping mechanisms photographed side by side on a cork background: a worm-drive clamp (the canonical form), a wing-nut clamp installed on a hose tail with hose attached, and a smaller two-bolt clamp.

Photograph by the project author. Released under the project's GNU GPL v3 or later license (the same license as the rest of BSPPFit that the project author owns). No external attribution constraints.

Photograph taken by the project author and embedded in the Taxonomy glossary under the Worm-drive clamp entry, with caption noting the three mechanisms shown and credited in Sources and Attributions. Slot is DONE.

Iteration 0.7.0 listed the Wikipedia Piping and plumbing fitting article as the candidate source for a composite figure showing the most common geometries side-by-side.

In iteration 0.8.0 the project author reviewed the article's coverage and noted that it mixes numerous other types of fittings outside our scope — compression, push-to-connect, sweat, sanitary clamps, trade-specific shapes that are not part of BSPPFit's BSPP-centred scope plus adjacent confusion classes. A composite figure drawn from this article would dilute the project's focus rather than support it.

Dismissed in 0.8.0. The geometry enumeration in F-01 of the Taxonomy stands without an overview figure for now; if a geometry overview is needed later it should come from the BSPP model library's renders, not from a third-party composite that conflates classes outside our scope.

Iteration 0.7.0 listed the Wikipedia O-ring article as the candidate. In iteration 0.8.0 the project author indicated a preference to provide own photographs for this slot rather than source externally; the slot is deferred pending those photographs.

No file in the project root. The forwarding paragraph in F-05 of the Taxonomy will be added when the photograph is available, framed alongside the bonded-washer entry and the cone-seat entry.

Deferred. The project author plans to search for a suitable diagram, provide one, or generate one when feasible. Tracked in FutureResearch.org (slot I-08).

This is the natural slot to be filled by an OpenSCAD render once the model library exists — the BSPT taper is a parametric construct that the library will already compute.

PNG raster of the historical printed plate

William Sellers (1864), public domain, via Wikimedia Commons.

Embedded in F-03 Comparison subsection of the Taxonomy as an informational historical plate showing three thread forms side by side. Together with the I-01 Whitworth SVG, this addresses most of the original I-01 ambition (a side-by-side comparison) while preserving I-01 as the technically-precise modern Whitworth profile.

The plate is from 1864 and pre-dates modern ISO and ANSI dimensional standards by more than a century. It is reproduced for visual comparison of the profile shapes (rounded vs truncated crests; 55° vs 60° angles; symmetric vs the older "usual workshop" asymmetric form). Modern dimensional values must come from the standards: ISO 228 (BSPP), ISO 7 (BSPT), ANSI/ASME B1.20.1 (NPT). The figure caption is explicit on this point.

Project author supplied the file in iteration 0.8.4 and provided the public-domain attribution. File placed under the project root as ThreeThreadForms.png (PascalCase per project convention). Embedded in F-03 of the Taxonomy with caption noting the informational status; credited in Sources and Attributions. New glossary entry Sellers profile added in F-03 thread-forms sub-section to give the plate a definitional anchor. Slot is DONE.

Project-owned geometry: bsppfit.scad (the G-01 straight family). No external source, no licence obligation — GPL-3. This is a single-fitting comparison, not a gallery: a focused two-fitting scene of a male fitting beside a female fitting.

gender-comparison

a male nipple (M × M) at left and a female socket (F × F) at right, both G1/2 hex, same size, so gender (external vs internal thread) is the only difference.

gender-comparison-cut

the same pair sectioned (BOSL2 BACK), showing the male's external thread / plain bore and the female's internal thread running the bore.

Viewpoint lat 35°, lon 270°; colour scheme Tomorrow; 1600 × 1200 — the same still scheme as zones B and C. Cut direction BACK coupled to the viewpoint. Regenerate:

• Nipple-gender-comparison-cut.png → Nipple-gender-comparison-cut_001+35+270.png

Illustrates the Gender facet in Taxonomy.org, Facet — Gender (F-02) as figures fig:gender-comparison (solid) and fig:gender-comparison-cut (cutaway), showing the gender distinction at the geometry level (external vs internal thread) to complement the section's thread-level explanation. Eleventh M-NN slot; the zone-A deliverable, completing the illustration programme (zones A, B, C and the D4 cross-reference pass all done).

Added the gender-comparison and gender-comparison-cut render variants (two-fitting scenes) to bsppfit.scad; rendered both stills at 35,270 and inspected (male external thread vs female internal thread reads clearly, and the cutaway makes it unambiguous); copied into the project root and linked under stable names; figures placed in the F-02 section; RENDER_STILLS, EXTRA_DIST and the dist-hook updated. Slot DONE.

Project-owned geometry: the nine model files (Nipple, Elbow, Cap, Plug, Union, Reducer, HexBush, HoseTail, Manifold). No external source, no licence obligation — GPL-3. Unlike the zone-B galleries (one gallery per model), these are single-fitting renders of each model's default configuration, for the lookup-driven reader who lands on a glossary entry.

Eleven fitting-types, each solid + cutaway (22 renders total):

• Nipple, Elbow, Cap, Plug, Union, Reducer, Hex bush, Hose tail, Manifold — the default / default-cut render variants.
• Tee, Cross — the tee~/~tee-cut and cross~/~cross-cut variants of Manifold.scad (tee and cross are configurations of the Manifold class, so they render from that model file).

Each model gained a default-cut render variant (the default fitting with cutaway = BACK, matching the zone-B cut convention); Manifold additionally gained tee-cut and cross-cut. The solid default (and Manifold tee~/~cross) variants pre-existed.

Viewpoint lat 35°, lon 270°; colour scheme Tomorrow; 1600 × 1200 — the same still scheme as the zone-B galleries. Single fittings read with more internal detail than the gallery cells (e.g. the hose-tail barb section and the union seat are clearer here). Regenerate any one, e.g.:

render-views --scad-file bsppfitTest.scad \
  --model-name Nipple-default \
  --render-variant nipple-default --still 35,270 \
  --colorscheme Tomorrow --imgsize 1600x1200 \
  --output-dir Renders/Nipple
# ...and default-cut, and likewise for each model;
# Manifold also tee / tee-cut / cross / cross-cut.

Or make render-archetype-stills (the RENDER_STILLS registry carries all 22).

Under the project root, the stable names are symbolic links onto the coordinate-encoded frames, e.g. Nipple-default.png → Nipple-default_001+35+270.png and Nipple-default-cut.png → Nipple-default-cut_001+35+270.png, for each of the 22.

Illustrates the fitting-type glossary entries in Taxonomy.org, Geometry and ports: each entry (Cap, Cross, Elbow, Hex bush, Hose tail, Manifold, Nipple, Plug, Reducer, Tee, Union) carries an inline fig:gloss-<term> (solid) and fig:gloss-<term>-cut (cutaway) adjacent to its definition. Tenth M-NN slot; the zone-C deliverable.

default-cut (and Manifold tee-cut~/~cross-cut) render variants added to the models; 22 stills rendered at 35,270 and inspected; copied into the project root and linked under stable names; inline figures placed in the glossary; RENDER_STILLS, EXTRA_DIST and the dist-hook updated. Slot DONE.

Project-owned geometry: bsppfit.scad (the G-10 unified branch-fitting class). No external source, no license or attribution obligation — GPL-3.

gallery-archetypes

solid 4 × 3 grid (perpendicular basics incl. tee and cross, leaning Y/X-forms, point/capped/mixed/ asymmetric variety).

gallery-archetypes-cut

cutaway companion (BOSL2 BACK half) showing the run bore and the branch-to-run junctions.

Viewpoint lat 35°, lon 270°; colour scheme Tomorrow; 1600 × 1200. The Manifold is a horizontal-run form (run along X, branches perpendicular), unlike the eight upright-form galleries, so the viewpoint was re-checked: 35,270 keeps the clean 4 × 3 grid and shows the branch arrangement and lean angles well (30,315 and 25,340 collapsed the grid into diagonal scatter).

Illustrates the G-10 Manifold entry in Taxonomy.org as figures fig:manifold-archetypes (configuration range: branch count and arrangement, lean angle, gender, end forms) and fig:manifold-archetypes-cut (run bore and branch-to-run junctions). Also covers G-03 Tee and G-04 Cross: the first two cells of each figure are the tee and cross configurations, so no separate Tee or Cross galleries exist. Ninth M-NN slot — completes the zone-B geometry galleries.

Viewpoint re-checked across three latitudes/longitudes (35,270 vs 30,315 vs 25,340); 35,270 chosen for grid integrity. Stills rendered, copied into the project root, linked under the stable names. Cut companion flipped FRONT → BACK to suit the viewpoint (verified by inspection; run bore and branch junctions read). Embedded in the Taxonomy G-10 subsection, with G-03 and G-04 cross-referencing the same figures. Slot DONE.

gallery-archetypes

solid 4 × 3 grid (assembled gender row, exploded gender row, single-pieces + larger-size row).

gallery-archetypes-cut

cutaway companion (BOSL2 BACK half) showing the internal conical seat, bore continuity, and the nut/collar coupling thread — the most informative view of a union, since the sealing seat is invisible from outside.

Viewpoint lat 35°, lon 270°; colour scheme Tomorrow; 1600 × 1200. Same viewpoint as the other upright-form galleries. Cut direction BACK coupled to the viewpoint — see the Development Standard and the 0.66.0 journal entry. Regenerate:

Illustrates the G-07 Union entry in Taxonomy.org as figures fig:union-archetypes (configuration space: pose × pipe-end gender × component pieces) and fig:union-archetypes-cut (internal conical seat and bore). Eighth M-NN slot.

Stills rendered at the chosen viewpoint, copied into the project root, linked under the stable names. Cut companion flipped FRONT → BACK to suit the viewpoint (verified by inspection; the exploded cutaways and the conical seat read clearly). Embedded in the Taxonomy G-07 subsection. Slot DONE.

Project-owned geometry: bsppfit.scad (the G-08 hex / reducing bush). No external source, no license or attribution obligation — GPL-3.

gallery-archetypes

solid 4 × 3 grid (M-large size-ratio row, F-large gender-swapped row, specials row).

gallery-archetypes-cut

cutaway companion (BOSL2 BACK half) showing the through-bore and the diameter step at the gender transition.

Illustrates the G-08 Hex bush entry in Taxonomy.org as figures fig:hexbush-archetypes (configuration space: gender layout × size ratio × hex height) and fig:hexbush-archetypes-cut (through-bore and gender-transition step). Seventh M-NN slot.

Stills rendered at the chosen viewpoint, copied into the project root, linked under the stable names. Cut companion flipped FRONT → BACK to suit the viewpoint (verified by inspection). Embedded in the Taxonomy G-08 subsection. Slot DONE.

Project-owned geometry: bsppfit.scad (the G-09 hose tail). No external source, no license or attribution obligation — GPL-3.

gallery-archetypes

solid 4 × 3 grid (barb-profile + shouldered row, body-shape × gender row, barb-count + size row).

gallery-archetypes-cut

cutaway companion (BOSL2 BACK half) showing the through-bore and — the point of the cut for this model — the barb wall profile in section.

Viewpoint lat 35°, lon 270°; colour scheme Tomorrow; 1600 × 1200. Same viewpoint as the other upright-form galleries. Note: the barb profiles (shark-fin, stepped, christmas-tree) are subtle on the solid exterior at grid scale — lower latitudes were tried (15, 20) but collapsed the grid into diagonal scatter, so the grid-legible 35,270 was kept and the cutaway carries the barb detail.

gallery-archetypes-cut

cutaway companion, each cell sectioned (BOSL2 BACK half) so the conical size transition and the eccentric offset bore read from the still viewpoint.

Viewpoint lat 35°, lon 270° (coordinate-encoded in the frame name); colour scheme Tomorrow; 1600 × 1200.
