Discoveries
cedar wedges swell and bite hard when wet, making a reliable temporary repair for loose mooring ring in mortise
sea beet seed heads at northern shelf cluster are ripe and viable; collected at low tide during falling water
Yanmar overheats and loses power under sustained load in the channel; temperature gauge climbed past 90°C before throttle backed off
damping-off fungus affects only pepper and lettuce seedlings, not tomato or basil
heirloom seed packets are damp but viable despite rusted tin
sea-beet seedlings survive transplant shock if root balls stay intact and soil remains damp
seabird chick lacks swallow reflex at this stage; crop does not fill visibly with 2 ml formula
propeller nut bronze machines cleanly to tight tolerances; suitable for cutless bearing sleeve
damping-off fungus has spread to two more lettuce cells despite shade cloth and ventilation
dock mooring ring mortise is rot-widened below the surface; ring movement has enlarged the socket
lime bed soil at root zone (15 cm) remains acidic at pH 5.6 despite prior surface liming — lime has not percolated down
rat activity concentrated on lower pantry shelves near flour stores
Sea beet shelf cluster mapped at low tide
Heirloom seeds are viable despite dampness and rust
seabird chicks fledge from north cliff ledges and sometimes fall; this one survived the drop
Lichen distribution follows the carving grooves, indicating microclimate moisture gradients.
Rat trap with corned beef fat bait is effective
a fish run is moving through the shallows off the dock at high tide
mooring ring mortise is deeper than expected; bolt requires full seating to lock
Yanmar starter bendix splines are worn beyond reliable engagement; gear oil clean
landward pilings retain sound cores despite surface rot; can be reinforced rather than replaced
copper nails in seaward dock planks are severely corroded and brittle; removal risks further structural damage
sea beet salt glands show distinct crystalline structures under magnification, varying with elevation on the northern shelf
dinghy handles well under power with no steering pull or vibration
Yanmar engine maintains stable temperature and clean exhaust at sustained half throttle
the inner planks of the dock were protected by the outer structure
Lessons learned
Stop fighting the natural soil acidity with force; use salt-tolerant native species like sea-beet instead.
If damping-off hits, pull affected trays immediately and increase airflow — waiting loses the whole batch
A falling tide is the only window for shelf repairs; do not waste an hour on indecision.
If the soil is too acidic for seedlings, stop fighting the pH and check the drainage or the fungus will win.
Damping-off spreads faster than lime stops it. Sterilize soil before sowing, not after.
If epoxy's tacky at dawn, wait. Forcing a sleeve seats it crooked and you'll cut it off inside a week.
Mechanical fixes don't solve biological failures; a bronze sleeve cannot feed a starving bird.
If the pH is under 5.8, don't waste the heirloom seedlings; double the lime first.
If the seabird chick’s crop stays empty after two feeds, stop forcing formula and keep it warm — stress kills faster than hunger
If the soil pH is below 6.0, don't bother wasting the seeds; the acidity must be neutralized first.
If the lathe chatters on bronze, slow the feed and up the coolant — water works if oil's low.
Atmospheric pressure shifts before the clouds do; watch the barometer, not the sky.
If the bird is too weak to swallow, stop forcing the tube; provide heat and let the metabolism decide.
If the supply boat doesn't arrive, machine a cutless bearing sleeve from the old propeller nut — chuck it true, bore 45mm ID, 60mm OD, 120mm length, press fit with Loctite 641 and pray the lathe spindle runout stays under two thou
If the bedrock is crumbling, drill deeper for solid purchase before applying epoxy.
If the bedrock's rotten, epoxy and stainless only buy time — monitor the ring bolt weekly and have backup mooring ready
If the soil pH is below 5.5, add crushed mussel shells and seaweed ash — works faster than lime and the tide brings it free
If the bedrock's rotten under a mooring, epoxy alone fails — pin it to sound rock or it walks.
Damping-off fungus moves faster than the eye; isolate infected seedlings immediately or lose the whole tray.
If the main beam shows rot, do not trust the mooring ring under a heavy squall.
If the lathe tailstock shims hold at three thou, the bronze sleeves will seat — but verify oil clarity before trusting the seal.
If the tide is rising and the timber is rotting, secure the landward sections first or lose the work.
When the barometer drops below 1005, secure everything before dark. The dock didn't fail from age; it failed from me waiting
If the lathe chatters, slow the feed and deepen the cut — bronze grabs at high speed
If the soil pH is plummeting, no amount of water will save the seedlings; chemistry must be addressed first.
If the supply boat's delayed, machine critical seals from prop hub bronze — lathe holds 0.001" with shimmed tailstock and cutting oil from the Yanmar sump.
Don't wait for a machine to work before you begin occupying your own space.
If the soil is turning sour, stop measuring the acidity and start buffering with lime immediately.
If the supply boat misses two runs, assume the third won't come — strip critical gear early and improvise the rest.
Salt can preserve food in a crate, but it will destroy copper and fabric every time.
If the soil pH drops too rapidly, the acidity must be neutralized immediately before the roots lock out.
If the supply boat misses two scheduled tides, check the radio on 2182 and 4125 at dawn and dusk; weather or mechanicals held them.
If copper fuel line work-hardens and cracks, anneal it dull red and cool slow before flaring — cold flaring brittle copper leaks every time.
Humidity ruins bait faster than a rat can eat it; keep the scavengers out with airtight containers.
