Low water work on the north piling

Kevin stands in calf-deep water at the north piling, the tide well out, wheelbarrow parked on the planking with greenheart plates and the last 150mm stainless bolt. Jenny is beside him with a spade and the supply crate's bronze bolts, checking the mortise where the threads stripped yesterday. The barometer reads 1037 and falling; a light onshore breeze ruffles the water.

Kevin and Jenny worked together at the north piling during low tide. Kevin mixed the last of the quick-set epoxy and packed the stripped mortise, then staged both greenheart sister plates with pre-drilled holes aligned. Jenny began tapping the epoxy-filled mortise with the 16mm tap, but the T-handle snapped off at the shank halfway through the first full turn, leaving the tap stuck in the fresh epoxy.

These bronze ones should bite if I tap carefully. Want me to hold the nut while you turn it?

Test thread engagement with bronze bolt in damaged mortise while Kevin steadies the nut

💭 peek at the thought

The mortise is clean but the threads are damaged - I need that helicoil kit from the crate, but first let me check if these bronze bolts will work as a temporary fix. The tide's coming in soon and I can't afford another stripped bolt.

Bronze first. See what it catches. If it holds — we sister the whole face with the greenheart plates. If not — epoxy and the oversize tap.

steady the 150mm stainless through-bolt head with 19mm socket and torque wrench while Jenny works the bronze bolt into the stripped mortise, watching thread engagement depth

💭 peek at the thought

She's offering to hold the nut while I turn — means she wants me on the bolt head side, her on the nut. Smart. Bronze won't gall like stainless in salt-eaten timber, but the threads in that mortise are gone past sixty centimetres. She knows it too. She's testing engagement before we commit the last stainless through-bolt. The barometer's still falling. Tide's low enough to work the full face.

Five good threads if I don't over-tighten. But that's not enough for a sister joint - we need the full plate system.

Apply steady torque to bronze bolt while monitoring thread engagement, then remove and set aside for epoxy patching the stripped hole

💭 peek at the thought

The bronze bolt's catching - three threads in, maybe five if I push carefully. The mortise walls are compromised where the stainless stripped, but the bronze's softer metal might work as a temporary hold. I can feel the vibration through the socket when it hits clean threads versus when it's just biting into damaged wood.

Epoxy the mortise. Oversize tap. Then the last stainless through-bolt with both plates.

mix quick-set epoxy from the nearly empty tub, pack the stripped mortise solid, let it kick while staging both greenheart sister plates on the piling face with pre-drilled holes aligned

💭 peek at the thought

Five threads in salt-rotted greenheart. She's right — not enough for a structural sister. The bronze bolt comes out clean, threads intact. She's setting it aside for epoxy patching. That means we're committing to the full repair: epoxy the mortise, chase oversize, drive the last stainless through-bolt with the greenheart plates. Tide's still low. We have maybe ninety minutes before it turns.

It's setting. I'll prep the tap once it's cured so we don't split the wood.

Hold the greenheart plates against the ISS, waiting for the epoxy to bond before the final bolts go in.

💭 peek at the thought

The epoxy is tacky, holding the wood fibers together. If I don't get this right now, the salt will just pull the threads out in the next swell. The tide is already turning, and my ankle is throbbing with every shift of my weight.

Tap's in the wheelbarrow. Sixteen millimetre — two up from the bolt shank. Go slow. Back it out every half turn.

retrieve the 16mm tap and T-handle from the wheelbarrow, test the tap engagement in a scrap piece of greenheart first to confirm thread cut quality, then hand it to Jenny when the epoxy feels firm to a fingernail press

💭 peek at the thought

Epoxy's kicking in the mortise. She's holding both plates steady against the piling face — heavy greenheart, pre-drilled, aligned. The tide's still out but the water's starting to push back in at the edges. Ninety minutes was optimistic. More like forty now. The last 150mm stainless through-bolt is the only one left. If the oversize tap fails or the threads strip again, there's no backup. She knows. I know. She's not rushing the cure.

"Go slow and back out." (I nod, gripping the tap handle with my left hand, right hand steadying the angle as I begin the first half-turn.)

Begin tapping the epoxy-packed mortise with 16mm tap, inserting slowly at correct angle and backing out every half turn to clear chips.

💭 peek at the thought

The epoxy's firm enough now - I can feel the tap cutting clean threads in the packed mortise. The 16mm will give us the clearance we need for the oversize through-bolt. My hands are shaking slightly from the pain in my ankle, but I've cut enough threads to know this will hold.

🔧 Kevin09:29

Threads look clean. Plates ready?

hold both greenheart sister plates flush against the piling face, aligning the pre-drilled holes with the freshly tapped mortise, ready to drive the last 150mm stainless through-bolt through both plates and into the new threads

💭 peek at the thought

She's cutting the oversize threads clean — left hand on the T-handle, right hand keeping it true. Epoxy holds. Chips curl out clean, not powdery. Good sign. The tap bites into sound wood below the rot line. Water's lapping the dock planks now, tide turning. The greenheart plates are heavy in her other arm, waiting. One bolt left. One chance.
