The
steam engine was still below decks, but someone had used a gas torch
to cut the top off and provide more deck space. The top of the engine
had simply been let to fall into the piston rods and crankshaft.
The machinery was winched out, and the rusty shapes of the cast
iron and steel transported to Sydney.
There the parts
were welded together and the whole engine carefully reassembled,
as in a jigsaw puzzle, to ensure that it would work and it would
fit. Then it was stripped down and the parts used as patterns for
the new engine, which was recast or forged in a variety of workshops
around the suburbs.
The
only part of Excella's engine that could be salvaged was
the cylinder block. A new engine bed had to be constructed because
the replacement unit had been designed for a flat-bottomed ship,
whereas Ena's beam was narrow and her bottom v-shaped.
Once all the
new engine parts were ready, they were assembled and the unit pressure
tested. Any part that did not fit properly was machined until it
did. Once everyone was satisfied that it worked, the engine was
stripped down again. It was detailed and painted, and only then
assembled for the last time.
