Every project in this book is tagged with a skill: carpentry, masonry, a bit of wiring, a little forge work. This chapter is the 101 on each of those trades, the plain fundamentals a beginner needs to actually build what came before. You will not become a master from a few pages, and some of this (house wiring, pressure vessels) is worth a professional's eye. But learn the basics of these nine trades and you can make and mend instead of buy and replace, and that is what truly off the grid means.
Measure true, cut square, join tight: the trade that builds almost everything.

Carpentry is measuring, cutting, and joining wood. The whole trade rests on a few habits: measure twice and cut once, keep everything level, plumb, and square, and let the joint do the work before the fastener. Learn to cut a straight square line, drill a true hole, drive a nail and a screw without splitting the wood, and make the basic joints (butt, lap, dado, and the mortise and tenon) and you can frame a wall, build a bed, or hang a door.
Tape measure, pencil, a framing and a combination square, a level, a handsaw and a circular saw, hammer, a drill-driver, a set of chisels, a block plane, and clamps. Keep edges sharp: a dull tool is a dangerous one.

Mud, stone, and fire-proof walls: the oldest building trade there is.

Masonry is building with stone, brick, block, and the mixes that bind them, plus the earthen cousins (cob, adobe, rammed earth, hempcrete). The core skills: mix mortar and concrete to the right ratio, lay level courses on a true footing, keep the wall plumb with a line, point and tool the joints, and build forms to pour into. Earth building trades the mortar for mud and straw but reads the same: a good base, level courses, and time to cure.

Heat it, hammer it, harden it: make and mend your own iron.

Blacksmithing is shaping metal, mostly hot, with a hammer. Learn to run a clean fire and read the heat by color (a glowing orange-yellow forges, bright white burns the steel), and the basic moves: draw out (lengthen), upset (shorten and thicken), bend, punch, and taper. For an edge tool, learn to harden (quench hot steel) and then temper (a gentle reheat) so it holds an edge without shattering. A hook, a hinge, a knife, and a chisel teach the whole trade.
A forge (coal, charcoal, or propane), an anvil or a hard steel face, a cross-pein hammer, tongs that fit your stock, a vise, a quench bucket, and files.

Join and cut steel: the fastest way to build and fix heavy things.

Welding fuses metal by melting it together. For the homestead, stick (arc) welding is the workhorse: cheap, simple, and it runs off a generator and works outdoors and on rusty steel. Learn to clean the joint, strike and hold an arc, run a steady bead, and tack before you weld a long seam. Pair it with an angle grinder to cut, clean, and dress the welds, and you can build or repair almost any steel thing.

Keep the engines, pumps, and gear running, and fix them when they stop.

An engine needs four things to run: fuel, air, spark, and compression. Lose one and it quits, so troubleshooting is just checking those four in turn. The rest is upkeep: change the oil, clean or replace the air and fuel filters, keep a fresh spark plug gapped right, and use clean fuel. Learn that, plus how to read a bearing, a belt, and a torque spec, and most of what breaks on a homestead you can fix yourself.
A socket and wrench set, screwdrivers, pliers, a feeler gauge, a spark tester, a multimeter, grease and oil, and the manual for each machine.

Wire your own power safely: volts, amps, fuses, and a solar chain.

Electricity is volts (pressure), amps (flow), and watts (volts times amps, the work done). Off grid you mostly run DC: a solar panel charges a battery through a charge controller, and an inverter turns the battery's DC into household AC. Learn to size your wire and fuse to the amps it will carry, wire in series (adds volts) or parallel (adds amps), ground the system, and read it all with a multimeter.

Move water where you want it, by gravity or pump, and keep it clean.

Plumbing is moving water through pipe. Water runs downhill and finds its level, so gravity does the work when you let it: every foot of height is pressure (head). Learn the common pipes (PEX for most runs, PVC for drains, poly for buried line) and how to join each (push-fit, crimp, or solvent-glue), how to slope a drain so it clears, where to put valves, and how to keep lines from freezing. Then a roof catch to a tank to a tap is just one sloped, fused-together run.
A pipe cutter, the crimp tool or glue for your pipe, an adjustable wrench, thread-seal tape, and assorted fittings and valves.

Twist a cord, spin a yarn, weave a cloth, and mend what tears.

Fiber work turns plant and animal fiber into cord, rope, and cloth. It all starts with twist: reverse-wrap two bundles of fiber against each other and they lock into cordage that will not come undone. Spin that finer on a spindle or wheel into yarn, lay cords together into rope (see Hemp), and interlace warp and weft on a frame or loom into cloth. Add a handful of knots and a saddle stitch and you can make and mend nets, bags, snares, and clothes.
A drop spindle or spinning wheel, a frame or loom, strong needles and an awl, and a few core knots.

Turn a hide into leather, rawhide, and sinew, and stitch it into gear.

Nothing off a butchered animal need be wasted, and the hide is a whole trade on its own (see Hunting). Learn to skin clean, flesh the hide (scrape off fat and membrane), and then choose: rawhide (just dried, hard and strong for lashings and drum heads), brain-tan or bark-tan (worked soft into leather), and sinew (dried back and leg tendon, pounded into the strongest natural thread there is). Cut leather with a sharp knife and join it with a saddle stitch (two needles, one seam) and it will outlast its maker.
