Internal float switch on bilge pump failed, replacing with salvaged float switch from another pump.
Installed Monday October 16. Need to add mild steel blank to prevent the pump floating off the sump sole and tipping with float disengaging before last few inches are pumped. |

Nautech Autohelm MK II tiller pilot
Compass drum mounting screw housing broken, drum mount twisted. Probably jammed in place due to drum tilt, resulting in spring stretched.
Rebuild including fabricating new drum mount.
Upon further examination of the interior of the autohelm casing there is evidence of the spring rubbing against the casing near the compass drum, depositing scrapings from the casing on the spring.
The question is now did the drum mount failure cause the spring to scrape against the casing or did the spring jamb against the casing and cause the drum mount to fail?
Longer wire cable and shorter spring? |

| New spring for cable tension |

| Epoxy for drum mount rebuils |
 |
| Epoxy at drum mount, to be shaped after 24 hr set. |
Ulladh
Ulladh pronounced "ul-la" (n
ull lad).
Uladh the gaelic spelling for the territory of the U-Nail chieftains in the ancient Irish province of Ulster (English/Norse), originally the counties of Down and Antrim, but now including Derry, Armagh, Tyrone, Fermanagh, Donegal, Cavan and Monaghan, also referred to as Ulidia (Greek/Roman),.
Uladh was the home of a pre-celtic, cruithne (crew-en-ya) pictish tribe, who may have been descendants of prehistoric tribes indigenous to the British Isles since the retreat of the last ice age.
Evidence from cut marks on deer bones from more than 30,000 years ago found in the karst formations of the Burren probably from hunters suggest a homonid precence.
Archeological finds date first inhabitants (DNA evidence suggests dark or black skin and blue eyes) to about 6,000 BC and trade goods from Rathlin Island, County Antrim off the northeast coast of Ireland made from porcellanite stone appearing in Egypt and Crete by 2,500 BC.
The early tribes of Ireland where displaced by later waves of migrants from mainland Europe; about 1700 BC by bronze age tribes, celtic tribes about 500 BC, and in the past two millenia; Roman trading posts, Viking settlements, English plantations... and in the 21st century a welcome increasing diversity from the European Union and the world.
SV Ulladh (for vhf clarity I use "sailing vessel ul-la") is named for the territory of the first peoples to settle in Ireland after the retreat of the last ice age.
