And in with the new …

After much contemplation, the “old” Lombardini LDW 502 M (acquired in March 2007, but with only 13 hours’ running time, all since March 2022!) is to be retired, rebuilt, looking for a new home. (See earlier posts “Grrrr” and “Good news, and less”.)

Ultimate cause of engine failure was inadvertent absence of anti-siphoning valve on raw water intake.

In its place, a new Lombardini LDW 702 M, bringing 18 hp and a cast iron block (compared to the 502’s 11 hp and aluminium block). Conveniently, the 702’s bottom end is precisely the same dimension as the 502, right down to location of the brackets for fitting to engine mounts and fitting to propshaft.

It’s just a bit fatter and taller. So it should drop straight in.

Inevitably, that is not what happened: the original engine mounts didn’t fit because one seems to have been relocated with adjustment of the old engine’s bracket to avoid internal structure; on adjusting the new engine’s bracket similarly, it was discovered one of the old engine mounts perished in a fuel leak (and they come in packs of four); deciding to replace all engine mounts, their epoxied bolts couldn’t be removed, so new mounts have had to be rotated by 15°; new mounts plus rotation exceeded necessary tolerances for commissioning certificate. Doubtless resolution will be found.

RIP Bruce Askew

Bruce Askew was long central to Rogue’s restoration. As explained elsewhere on this site, his enthusiasm for returning Rogue to her 1892 flush-decked gaff-rigged configuration initiated the project. Rogue bookended Bruce’s maritime life: as a schoolboy, his curiosity about (sledgehammer) attempts to give Rogue’s replacement cast-iron ballast a more hydrodynamic form led to a lifetime in marine architecture; Rogue’s return to the water earlier this year was the culmination of Bruce’s design, drawings and many other contributions (including observing the sledgehammer marks on the original ballast, and crafting beautifully turned samson posts and pin rail and a 1:15 model) over the years. A larger account of his history is on the RPNYC’s website. Rest in peace, Bruce.

Good news, and less

Muscled-up cockpit seats are back in, as are the backstay runner levers on realigned bases, and safety bars fitted to the butterfly hatch (necessary for crew safety, as everyone automatically places a bracing foot there when working around the mast, but regrettably obscuring Sarah Maxey’s etching). Below, dogs finally have been sourced to secure the butterfly hatch closed.

Less welcome is the disassembled engine. Source of water in oil is as yet unclear, both exhaust and water intake being routed well above the waterline. Somehow it appears the gravity-fed sump has become pressurised, so that oil is blown back into engine, perhaps bringing bilge water with it. Investigations continue.
