Sibert follow-up: USD 250k budget, current VS specs, OMS as galvanics option

Ian Locke's email of 5 October 2026 after Making Vinyl Europe:

- Budget of USD 250k for VSP, VSF and VSC confirmed; his time, spares,
  shipping and travel extra; itemised quotation on request. The
  total-investment block keeps its estimate until the re-base, the
  difference (+190k low case / +80k high case) goes into the
  not-yet-rolled-up table.
- Current specifications filed (VSF and VSC 2022, VSP 2023) plus the
  VSF/VSP/VSC line-up drawing (4958 x 833 mm); the 2021 issues move to
  sibert/specs-2021/. VSC is now 1000 kg with split OD hydraulic / ID
  pneumatic forming; VSF 0-30 psi, 4-station head. Crane table, supplier
  map, vendor landscape and the plant page details updated.
- Fully automatic VSPa exists; Sibert offers to move features to the VSP.
- Electroforming: OMS (Optical Media Services, Lou Wullms) named next to
  Pheenix; added as a third galvanics candidate with open questions.
- Sequencing advice (presses, boilers, operators and live feedback loops
  first) recorded in the exhibitor briefing, roadmap item 23, and as
  digital-factory design decision 9 (operators see the data first).
