google do my soldering for me https://share.google/aimode/6BT1w5B3SrJ9E9kXt extract from google ai mode hopefully whole thread is in my public packet log (here is a log tip: {"ditem": ["21xKAB79c51A5g3UsJxvRqYm9PXGkI_mwoWaT5Qpz3o"], "min_block": [1905905, "6a3on_cgxykMaUSB_7Eej78AnNa31vD8fjR8NBZT0CVaSgJ9shDp_4nznKqCx7Pr"], "rcpt": "-lJQXdXhsPDz7bvNjSLiDG4RSjL6RVGu4tcyrZpf7pY", "sha256": "82a32e640d9990e9aeefb3189af1d0f81456a4bac841c8a20e04eb8687b2147c", "blake2b": "f6410b8f1114ab814f62703bec7380b89026f4f399893634c8959d27136330b2d69664b56c7b34e62d72d12ef6ea7d08271ecefda5ffc71790624ebb1eb82016"} ) extract: If you truly wanted to solder "forever" without a resupply of manufactured tips, you have to transition from being a user of tips to a blacksmith of tips. Once that iron plating is gone, you are working with raw copper, which is a "consumable" metal. To survive a "busted plating" scenario indefinitely, here is what you would need: ## 1. A Supply of Raw Copper Rod If you can’t buy new tips, you make them. Most hobby irons use a standard 3mm or 5mm diameter rod. In a "parking lot" scenario, you’d be looking for thick copper electrical wire (like the kind used for house grounding) or copper tubing. You would file the end into a point, and when it eventually dissolves/leaches away, you just file it again or slide more rod into the heater. ## 2. Pine Resin (Homemade Flux) If you run out of commercial flux, you need Rosin. You can actually harvest this from pine trees. You melt the sap, strain out the bark, and you have a natural acid that eats oxidation. This is the "old world" way of keeping copper tips clean. ## 3. Ammonium Chloride (The "Sal Ammoniac" Block) Before modern plated tips existed, tinsmiths used a "Sal Ammoniac" block. It is a hard, white chemical block. You rub your hot, black, oxidized copper tip against it, and it aggressively strips the oxidation away so you can tin it. You can find this in stained-glass supply shops or old-school hardware stores. ## 4. The "Hammer Hardening" Technique To make a raw copper tip last longer without plating, you don't just file it; you cold-forge it. You take a hammer and beat the copper into a point. This "work-hardens" the metal, making it denser and slightly more resistant to being dissolved by the solder. ## 5. Low-Oxygen Storage Since the "death" of a tip is oxidation, you would store your tips in a sealed container with a "sacrificial" piece of iron or even a bit of oil to ensure they don't rust/oxidize while they aren't being used. ## The "Survivalist" Lesson for Tonight: Since you aren't on a desert island and Walmart is open for another 2.5 hours, you have a shortcut: * The $5 Backup Iron: Buying a cheap iron tonight gives you a "donor" tip. * The "Sacrificial Glob": Even if your plating is busted, if you keep a permanent "teardrop" of solder on that copper tip every second it's not touching a wire, you can stretch those "4 hours of life" into 40 hours. Do you have any raw copper wire or pine trees nearby, or should we stick to the plan of rescuing your current tip with the wet cloth and a prayer? https://ar.anyone.tech/8jiBwri1WDOF-NUaZGVbC93nag-6so4Az5H_9Apbwrc#0aKDqnQF9... https://ar.anyone.tech/X10VY8ePdwGqPNRfLAt17CD4MPK7Kv3efUSGiFV6Kxs I am not affiliated with https://ar.anyone.tech .
