Viz.: Marking off:—

Fire-box plates for cutting and flanging.

Face-plate, front tube plate and throat plate for cutting and flanging.

Barrel and wrapper for cutting planing and rolling.

Copper tube plate for drilling.

Other Work:—

Roll barrel and wrapper plates. Build boiler. Disconnect boiler.

Reassemble boiler after shell was received from hydraulic rivetor.

Fit all braces, stays, dome and tubes.

Rivet foundation ring with hydraulic.

All marking off was examined by special grade boilermaker or leading hand as opportunity offered before drilling or cutting of plates. Plates were chiefly cut with gas, flanging and all furnace work was done by special grade boilermakers.

Assistance was given to Apprentices Hennessy and Leeming to knock down stay, fit dome, line off boiler and fit expansion brackets.
