Monocoque tub — chassis jig pickup points under review.
Pre-machining design check
Verified against the mould / chassis jig before any carbon is cut.
| Check | Nominal | Actual | Tol | Result |
|---|---|---|---|---|
| Tub wall laminate thicknessPly book matches CAD. | 3.2 mm | 3.2 mm | ±0.2 mm | Pass |
| Bulkhead bond-line gapAdhesive gap OK. | 0.30 mm | 0.30 mm | ±0.10 mm | Pass |
| Roll-hoop mount pitchCAD pickup points do not match the chassis jig — 7.5 mm short. Caught before CNC; DO NOT cut tooling until resolved. | 420.0 mm | 412.5 mm | ±0.5 mm | HOLD |
| Suspension pickup datumDatum aligned. | X0 datum | X0 datum | ±0.25 mm | Pass |
This job cannot go to the CNC until the check is cleared. Caught here, it costs a CAD revision. Missed, it's a laid-up part on the floor.
