The traveler is the sheet that follows a part around the building and gets signed at every station. These are eight of them, most recent first, reproduced as they were closed out. No photographs, because a photograph of a finished weldment tells an estimator nothing that the route and the held tolerance do not tell him better.
8 jobs, 40 operations between them. Customer names and drawings stay with the customer; the route and the number we held to do not.

Galvanizer set the schedule. Parts were vented and drained to the coater drawing so nothing came back for rework.

Pin holes were welded oversize and bored after the assembly cooled, because welding distortion moves a bored hole and nothing else will bring it back.

Waterjet rather than plasma - a plasma edge in thin aluminium work-hardens and cracks on the brake.

Mitred on the saw, not flame-cut. The fit-up gap was under a sixteenth all round, which is why the frame came out flat.

Flats were left on both ends and trimmed after the longitudinal seam, so the course closed round instead of egg-shaped.

Tread supports were nested and cut as a set so every stringer in the run got the same pitch.

Cut and drilled only. Abrasion plate is not formed here - the bend radii it needs are the customer engineer call, not ours.

Flat patterns were developed here from the finished geometry. The customer sent a formed model and no blank.
