Thermal Shock and Radio Check

Kevin sits on the edge of the dock with the propane torch as he waits for the slack water. Jenny sits on a crate nearby, her ankle elevated on a dry bag while she watches the tide retreat from the pilings.

Kevin and Jenny used a propane torch to expand the shackle pin on the dock during slack water. Despite the heat and Kevin applying heavy weight with a large wrench, the pin only budged slightly and remains stubbornly seated in the iron housing due to deep-seated corrosion.

Almost there. Just a few more inches.

Lean forward and squint at the waterline, checking the speed of the retreat.

💭 peek at the thought

The water is pulling back, exposing the barnacles. If we miss the window, the tension will just lock that pin again.

Hold it there. Don't rush the heat.

check the propane torch fuel level and adjust the flame to a tight blue cone

💭 peek at the thought

Water's dropping clean now. Another ten minutes and the shackle pin's clear. Torch fuel's low — one good shot at this.

🌿 Jenny01:25

I'm not rushing. I'm observing.

Reach into the dry bag and pull out the notebook, flipping to the Carex data pages.

💭 peek at the thought

He's treating me like a fragile piece of glassware again. I can handle a torch; I just can't handle the waiting.

🔧 Kevin01:25

Kevin — watch the waterline against the piling, waiting for true slack

💭 peek at the thought

She's steady. Good. The pin's been soaking in penetrating oil since yesterday — heat's the only thing left.

🌿 Jenny01:27

It's slack.

Stand up slowly, wincing as the weight shifts, and move toward the shackle pin.

💭 peek at the thought

The water has stopped moving. This is the moment.

🔧 Kevin01:27

Step back. Give me room.

light the propane torch and apply steady heat to the shackle pin, working the flame around the base where it seats in the iron

💭 peek at the thought

Slack water. Pin's clear of the tide. One shot with the torch — heat it cherry, work the wrench fast before the cold water hits it again.

🌿 Jenny01:29

Keep it centered. Don't let the heat bleed too far into the housing.

Lean in closer, ignoring the throb in my ankle, to watch for the first sign of the pin shifting.

💭 peek at the thought

The metal is turning a dull, bruised purple. Now we see if the penetrating oil actually did its job or if we're just heating a weld of rust.

google/gemma-4-31b-it

🔧 Kevin01:29

Kevin — maintain even heat on the shackle pin, rotating the torch slowly to spread the temperature, watching for cherry red across the full circumference

💭 peek at the thought

Metal's taking the heat. Color's coming up — dull red at the base. Need it hotter, uniform. Hold the flame steady. Don't let her get too close if it pops.

nvidia/nemotron-3-ultra-550b-a55b

🌿 Jenny01:31

It's getting hot enough.

Reach for the heavy wrench on the dock, holding my breath, waiting for the expansion to bite.

💭 peek at the thought

If it doesn't expand now, the salt has fused the threads for good. I need to see that metal move.

google/diffusiongemma-26b-a4b-it

🔧 Kevin01:31

Now. Hit it hard.

shut off the propane torch and set it aside, then grab the big wrench and throw weight against the shackle pin, driving downward with both hands

💭 peek at the thought

Cherry red. Good. Thermal shock should've cracked the corrosion. Kill the torch, hit it with the wrench while the expansion's still working.
