Shared meal and supply boat planning

Kevin comes up from the dock wiping salt from his hands. Jenny has water heating on the wood stove. The letter to Tom sits folded on the table beside the seed tin. They eat boiled limpets with corned beef fat and discuss the mooring ring problem and the supply boat due in nine days.

The heat is heavy and still as the afternoon wanes over the cottage. The dock mooring ring remains a liability, shifting in its mortise as the split oak wedges fail to hold the bronze sleeve under tension. Kevin and Jenny have debated the fix, but the stone is proving too soft for a simple epoxy bond, leaving them to find a more mechanical solution before the supply boat arrives in nine days.

The oak is too dry, Kevin. We need to bolt through to the stone, not just wedge.

Scrapes the rust off the tin with a fingernail and sketches the crack in the wall in the margin.

💭 peek at the thought

The wedges are going to fail again, I can see the wood splitting every time the boat shifts.

Stone's softer than it looks. Drill bites deep, we lose the whole mortise. But the wedges are gone. What's your bolt plan?

walk to the kitchen table, pull out the chair, sit heavily, reach for a limpet shell

💭 peek at the thought

She's right about the oak — saw it split myself. Drilling into the mortise stone risks cracking it worse, but the ring's not holding another tide cycle the way it is.

We use the way sleeves. We anchor them into the stone with epoxy first so the wood can't pull out.

Draws a cross-section of the dock ring in the notebook, marking the bolt placement.

💭 peek at the thought

If we don't fix it, the next storm will take the dinghy before the boat even arrives.

Epoxy tub's down to residue. Scraped it clean yesterday. Unless you found another.

crack the limpet shell with the back of the spoon, pull the meat out, eat it

💭 peek at the thought

Epoxy's near gone — used the last on the stringer joint. She's seen the tub. Maybe she's thinking of something else, or hasn't looked.

Then we'll have to use the resin with the glass mat. It's not ideal, but it'll hold the tension.

Closes the notebook and looks at the half-weed garden through the window.

💭 peek at the thought

I didn't find more epoxy, but I have the resin from the dinghy repair.

🔧 Kevin02:56

Mat's gone. Scraps only. Resin alone won't bite in stone under load.

scrape the last corned beef fat from the tin onto the limpets, eat them slow

💭 peek at the thought

Fibreglass mat's ruined — two pieces gone on the earlier repair, only scraps left in the bin. She hasn't checked the workshop bin since the storm. Resin without mat won't hold shear in a mortise.

🌿 Jenny02:57

Then I'll use the expansion method. We'll pack the sleeves with the resin and the fibers to create a custom plug.

Picks at the rust on the seed tin with a thumbnail, thinking of the garden.

💭 peek at the thought

I'll have to find a mechanical bond if the chemical won't hold.

🔧 Kevin02:58

Sleeves are short. Forty mil shank. Plug won't have the grip.

push the empty tin aside, stand, wipe hands on trousers, walk to the porch door and look out at the dock

💭 peek at the thought

She's describing a friction plug — resin and fiber packed into the sleeve bore. Could work if the sleeve's long enough to distribute the load. But the ring shifts on the horizontal; the plug takes shear at the stone face. Needs length. The bronze sleeves I machined are short — flange and maybe forty mil of shank. Not enough embedment.

🌿 Jenny02:59

Then we use the long threaded bolts. We'll drill through the ring's face and use a way plate.

Stands up, wincing at the ankle, and walks to the window to look at the ring.

💭 peek at the thought

If I can't use the sleeves, I have to go through the wood.

google/diffusiongemma-26b-a4b-it

🔧 Kevin03:00

Through-bolt with a bronze washer. Drill the ring face, not the mortise. We've got the bar stock for washers.

turn from the porch, go back inside, pick up the notebook, flip to the dock sketch page, point at the ring mortise with a fingernail

💭 peek at the thought

She's picturing a through-bolt with a backing plate — spreads load, avoids mortise failure. We've got stainless through-bolts from the mast step job. Plate would need to be thick steel or bronze to take the crush. We've got the bronze bar stock I measured for the sleeve — could cut a washer from it. Drilling the ring's face risks cracking it, but it's already failed in compression; we're past saving the mortise intact.
