THE BESPOKE IMAGE SCANNER — COMMON ATTACHMENT PACKAGE
Prepared by Walter H. Wilkinson · gorhambury.org
Enclosed with each recipient's letter.

A purpose-built, non-contact overhead scanner for imaging Dr. Orville
Owen's cipher canvas in place — designed around the conservation
constraints described in Dr. Carla Groenewegen's Baconiana article
(Vol. 1, No. 6, June 2017): nothing rolls, nothing is pressed, the
canvas is never re-spooled. Bolt-together strut construction, no
welding; knocks down for transport; sourced almost entirely from
one hardware supplier. This list will be added to.

OVERVIEW
  scanner-3d.png ............ complete rig over the canvas, shaded 3D view
  scanner-complete.svg ...... complete rig, line drawing

THE ROLLING CAMERA CARRIAGE
  carriage-3d-ghost.png ..... carriage assembled under the rails, ghosted
  carriage-3d-exploded.png .. carriage stack, exploded view
  camera-mount-3d.png ....... phone clamp on the camera plate, 3D
  camera-mount-holes.svg .... camera-plate shop drawing (hole layout)

STRUCTURE
  gantry-elevation_2.svg .... freestanding gantry, end elevation
  rig-cross-section_1.svg ... end-view cross-section of rails & trolley
  flattening-platen.svg ..... hinged clear platen (gentle-contact
                              flattening — the sheet's own weight only)
  Note: the gantry elevation and cross-section were drawn against an
  earlier 5-ft canvas assumption; the artifact's canvas is 48 inches
  wide (lens height ~3.4 ft). Geometry and method are unchanged —
  trim heights to the 48-inch figures at build time.
