๐Ÿ”จ The Workshop

Fixing beats replacing when there is nothing to replace with. The habits, the fix-it trees for the machines that matter, and the crafts that make consumables. Knots live on the one-pager shelf.

๐Ÿงญ The fixer's habits โ€” before any repair

  1. Make it safe: unplug it, depressurize it, let it cool, chock it. The machine can wait; fingers don't grow back.
  2. Look before you wrench: half of all faults are visible โ€” a loose wire, a split hose, a jammed thing. Clean it first; dirt hides cracks.
  3. Change ONE thing, then test. Two changes at once teach you nothing.
  4. Lay parts out in removal order (a cloth with rows; photograph or sketch each stage). Reassembly is the film in reverse.
  5. Righty-tighty, lefty-loosey โ€” and if it won't turn, penetrating oil and patience beat force and a snapped bolt. Heat is the second resort, never near fuel.
  6. A repaired thing gets a TAG: what failed, what you did, the date. The next fixer (maybe you) inherits the story.

๐Ÿšฒ Fix-it trees โ€” the machines worth keeping alive

The bicycle โ€” the most efficient machine ever built

Flat tire: lever the bead off, find the hole (pump + listen, or dunk), rough the patch spot, glue thin, wait till tacky, press hard; check the tire wall for the thorn that did it before the tube goes back. Slipping chain: usually stretch โ€” measure 12 links; over 12โ…›" (30.9 cm) it's done, swap or shorten. Oil the chain, never the rims. Rubbing brakes: loosen, squeeze the lever hard, retighten while held.

The hand pump / well pump

No water: prime it (pour water in the top till it catches). Weak lift: the leather/rubber cup valve is worn โ€” a cut piece of boot leather, soaked, replaces it. Gritty grinding: sand in the cylinder; lift, rinse, and add a gravel-and-cloth pre-filter at the foot valve.

The small engine (generator, tiller) โ€” three needs: fuel, spark, air

Won't start, in order: fresh fuel reaching the carb (old gas gums โ€” drain the bowl)? Air filter clean? Spark โ€” pull the plug, ground it against the block, pull the cord: no blue snap = clean/gap the plug (~0.7 mm) or swap it. Runs then dies: breather hole in the fuel cap blocked. Surging: carb jet gummed โ€” carb cleaner through the jet, or soak overnight.

The box itself (the computer serving this page)

Won't boot: reseat RAM and cables โ€” most "dead" machines are a walked connector. Overheating: dust from the fans and fins, a drop of oil in a screaming fan's hub under the sticker. Dying disk: the seed vault stick IS the backup โ€” clone a new box from it (README-FIRST tells a stranger how).

Mains electricity (wall power) is a different animal from the Spark's 12 V: it kills silently. Breaker OFF, test that it's truly dead, one hand behind your back on anything you're unsure of โ€” and if you're unsure, leave it dead and live without that circuit.

๐Ÿชš Wood, kept simple

  1. Square with a rope: 3-4-5 โ€” any triangle with sides 3, 4, 5 (any unit) has a true right angle. Whole buildings are squared with string and this.
  2. Measure twice, cut once โ€” and mark the WASTE side of the line so the saw's width doesn't steal your length.
  3. The joints worth knowing: the lap (two halves notched to overlap), the dado (a groove a shelf sits in), and the humble screwed butt joint with a glue block. Fancy joinery is for later; these build furniture, coops, and doors.
  4. Wood moves with the seasons โ€” across the grain, never along it. Leave a coin's gap where wide boards meet a frame.
  5. Sharpening is the master skill: a dull edge is dangerous, a sharp one is easy. Flat stone, consistent angle (~25ยฐ for chisels/knives), burr raised then stropped off on leather. Learn it on the kitchen knife; it transfers to everything.

๐Ÿงต Cloth, soap, and light โ€” the consumables you can make

  1. The four stitches: running (fast seams), backstitch (strong seams), whip (edges and tears), and the button. A tear mended today is a rag saved from tomorrow. Patch OVER the hole on the inside, stitched at the edges โ€” double cloth outlives the garment.
  2. Darning a sock: weave, don't sew โ€” threads laid one way across the hole, then woven through the other way. A lightbulb or smooth stone inside holds the shape.
  3. Soap is fat + lye + patience. Lye from hardwood ash steeped in soft water (an egg floats showing a coin-size top = strong enough); rendered fat strained clean; combined warm, stirred to thick honey ("trace"), poured, cut in a day, CURED SIX WEEKS. Lye burns skin and blinds eyes โ€” gloves, eye cover, add lye TO water never the reverse, vinegar on splashes. Fresh soap is still harsh; the cure tames it.
  4. Candles: any fat or wax, a braided cotton wick (soaked in strong salt water and dried burns cleaner), dipped or poured in a jar. A wick that smokes is too long โ€” trim to 6 mm.
  5. Cordage from nothing: twist a bundle of long fibres (bark strips, dry grass, plastic bags) tight until it kinks, fold at the kink, and let the two halves counter-twist around each other. Add fibre before each half thins. This is rope, and it held the world together for ten thousand years.

๐Ÿงฑ Shelter that lasts

  1. Water is the enemy; everything else is detail. A roof that sheds, walls that shed what the roof misses, and the ground sloped AWAY on every side.
  2. Wet feet rot buildings: anything wooden stands on stone, brick, or gravel โ€” never bare earth.
  3. Adobe/cob (where it's dry): 3 parts sandy soil, 1 part clay, chopped straw through it, trodden wet, formed in greased molds, sun-dried two weeks. Test your soil: a jar of it shaken in water settles sand below, clay above โ€” read the layers and adjust. Adobe wants a good hat (wide eaves) and good boots (stone base).
  4. Heat rises and drafts kill comfort: seal the top of a room before the walls, and put the thermal mass (stone, brick, water barrels) where the winter sun lands.
