# Wood and Metal Shop Craft: Layout and Marking, Hand Tools, Sharpening, Machines, the Table Saw, Joinery Technique, Glue-Ups, and Wood Finishing

> **Part 2 of 5** of the *Working with Wood and Metal* reference (plugin `working-with-wood-and-metal`), covering §5–§12. Sibling skills: `shop-materials-safety-reading-wood-and-stock` (§0–§4), `shop-metalwork-cutting-drilling-and-machining` (§13–§18), `shop-welding-forging-heat-treatment-and-shop-setup` (§19–§26), `shop-reference` (§27–§32). Section numbers are shared across the set; a reference written as §N → `skill` points into that sibling skill.
>
> **Currency:** The craft is centuries old. Two areas moved. See §27 → `shop-reference` for US table saw safety regulation, and welding fume exposure control.

> **⚠️ Two materials that punish opposite mistakes.** ⚠️ **Wood MOVES forever and forgives
> imprecision; metal is dimensionally stable and forgives nothing.** **⚠️ Wood is worked
> with the grain and cut fast; metal is worked against resistance and cut slowly.**
> **The habits that make you good at one will actively hurt you at the other.**
>
> **Complements a manufacturing reference (industrial process and tolerancing), a
> materials/furniture reference (wood movement and finishing at the design level), and a
> thermodynamics reference (heat treatment physics).**
>
> **⚠️ SAFETY IS §2 → `shop-materials-safety-reading-wood-and-stock` AND IT IS FIRST FOR A REASON.** ⚠️ **This document describes techniques;
> it does not substitute for supervised instruction on machinery. The table saw, angle
> grinder and welding arc each injure large numbers of people every year, and the
> mechanisms are specific and learnable.**
>
> **⚠️ GOTCHA** boxes mark the habits that cause injuries and the received wisdom that's
> wrong.
>
> **The three ideas that organize this document:**
> 1. **⚠️ SHARP IS SAFE** (§7). **A dull tool requires force, force removes control, and
>    loss of control is how people get hurt. Sharpening is not a side skill — it's the
>    gateway to everything else.**
> 2. **⚠️ The material is not neutral** (§3 → `shop-materials-safety-reading-wood-and-stock`, §14 → `shop-metalwork-cutting-drilling-and-machining`). **Wood grain direction, and metal's
>    heat and work-hardening behaviour, determine technique. Fighting the material is
>    the definition of doing it wrong.**
> 3. **⚠️ The invisible hazards are the ones that get you** (§2 → `shop-materials-safety-reading-wood-and-stock`, §26 → `shop-welding-forging-heat-treatment-and-shop-setup`, §27.2 → `shop-reference`). **Wood dust
>    and welding fume are classified carcinogens with no warning symptoms — and they're
>    the risks hobbyists systematically ignore in favour of the dramatic ones.**

## §5. Layout and Marking

**⚠️ Accuracy is decided at layout, not at the cut.**
⚠️ **A MARKING KNIFE beats a pencil: it severs the fibres, giving a line you can register a
chisel in, and it's an order of magnitude more precise.**
**⚠️ Marking gauge, combination square, try square, sliding bevel, winding sticks (⚠️ for
seeing twist), and story sticks.**
**⚠️ The principles that prevent cumulative error:**
```
⚠️ WORK FROM A SINGLE REFERENCE FACE AND EDGE — mark them, and
   register every measurement from them
⚠️ ⚠️ TRANSFER rather than MEASURE wherever possible. Hold the piece
   against its mate and mark it. Numbers introduce error; direct
   transfer doesn't
⚠️ CUT TO THE LINE, and know which side of the line the kerf takes
⚠️ MARK YOUR WASTE so you cut the right side
⚠️ Check SQUARE with the square you'll use throughout — and check
   that the square is actually square
```

---

## §6. Hand Tools

```
⚠️ SAWS  rip (⚠️ teeth like chisels, cut along grain) vs crosscut
   (⚠️ teeth like knives, sever fibres). ⚠️ Western saws cut on the
   PUSH; Japanese saws cut on the PULL (thinner kerf, less force)
⚠️ PLANES  jack (rough), jointer (⚠️ long sole = flat), smoother
   (final surface), block (end grain), shoulder/rabbet (joinery)
   ⚠️ A plane is a jig for holding a blade at a fixed depth —
   the SOLE flattens, the iron cuts
⚠️ CHISELS  bench, mortise, paring. ⚠️ Bevel up or down changes
   the cut direction
⚠️ SCRAPERS  ⚠️ a burnished hook that cuts a real shaving —
   excellent on figured wood where planes tear out, and on finish prep
⚠️ BRACE and bits · spokeshaves · rasps and files · mallet
```
**⚠️ Hand tools remain genuinely competitive for**: ⚠️ **fitting joints (paring to a line),
small work, awkward geometry, quiet operation, and finish quality — a well-planed surface
is better than a sanded one and needs no abrasive.**
**⚠️ The workholding is half the skill**: ⚠️ **a bench with a good vice, dogs and a planing
stop does more for hand tool work than any individual tool.**

---

## §7. ⚠️ Sharpening

> **⚠️ The gateway skill. Everything about hand tool work — and the safety of it — depends
> on this, and it's the step beginners avoid.**
```
⚠️ WHAT SHARP IS  ⚠️ two polished surfaces meeting at zero radius.
   ⚠️ Dull is a rounded edge, and a rounded edge requires FORCE
⚠️ THE PROCESS  establish the bevel (coarse) → refine (medium) →
   polish (fine) → ⚠️ REMOVE THE BURR on the back
⚠️ THE FLAT BACK IS HALF THE EDGE. ⚠️ A new chisel's back usually
   needs flattening once, properly, and then never again
⚠️ MEDIA  oilstones · waterstones (fast, need flattening) ·
   diamond plates (⚠️ stay flat, good for flattening other stones) ·
   ceramic · ⚠️ stropping with compound for the final polish
⚠️ ANGLES  ⚠️ roughly 25° primary, 30° secondary micro-bevel for
   bench chisels and plane irons — steeper for harder use, shallower
   for paring. ⚠️ The micro-bevel means you only hone a sliver
⚠️ HONING GUIDES  ⚠️ no shame in one; repeatability beats machismo
```
> **⚠️ GOTCHA — SHARP TOOLS ARE SAFER TOOLS, and this is counterintuitive to beginners.**
> ⚠️ **A dull chisel requires force; force means the tool skates or breaks free
> unpredictably and travels toward your hand.** **A sharp one cuts where you put it.**
> **⚠️ The same logic applies to saw blades, drill bits and turning tools — a dull blade
> also burns, binds and increases kickback risk** (§9).

**⚠️ Machine sharpening**: ⚠️ **grinders overheat and BLUE the steel, destroying the temper
— use light passes, a coarse friable wheel, and keep it cool.** **⚠️ Blue means you've
ruined that edge and must grind past it.**

## §8. Machines

**⚠️ Each machine has a characteristic hazard, and knowing it is most of using it safely.**
```
⚠️ TABLE SAW  ⚠️ kickback and blade contact — see §9
BANDSAW  ⚠️ the safest big machine (blade cuts DOWN into the table);
   ⚠️ blade drift, tension, and guide setup are the skills
MITRE SAW  ⚠️ climb-cut grab on wide stock; keep hands well clear
⚠️ ROUTER  ⚠️ feed direction matters enormously — ⚠️ CLIMB CUTTING
   (feeding with the rotation) pulls the tool and can snatch it out
   of your hands. Small bits spin very fast; large bits need slower speed
⚠️ JOINTER  ⚠️ hands over the cutterhead. Push blocks, always
THICKNESSER/PLANER  ⚠️ snipe, and ⚠️ NEVER reach into the outfeed
DRILL PRESS  ⚠️ clamp the work — a bit grabbing sheet metal or a
   small part turns it into a spinning blade
LATHE (wood)  ⚠️ catches, and ⚠️ face shield not just glasses
```
**⚠️ Blade and cutter selection** matters more than machine cost: ⚠️ **tooth count and grind
for the material and the cut, sharp carbide, and the right feed rate.**
**⚠️ Featherboards, push sticks, zero-clearance inserts and sleds** are ⚠️ **engineering
controls (§2 → `shop-materials-safety-reading-wood-and-stock`) and they improve accuracy as well as safety, which is the argument that
actually persuades people.**

---

## §9. ⚠️ The Table Saw

> **⚠️ Singled out because it causes more serious injuries than any other woodworking
> machine, and because the mechanism is specific and preventable** (§27.1 → `shop-reference`).
```
⚠️ KICKBACK — the dominant mechanism
   ⚠️ WHAT HAPPENS: the workpiece pinches the blade or contacts the
   REAR of the blade (which is rising and moving TOWARD you), and
   is thrown back at high speed — often taking the operator's hand
   into the blade with it
   ⚠️ CAUSES: no riving knife/splitter · using the FENCE AND MITRE
   GAUGE TOGETHER (⚠️ traps the offcut — a classic and serious
   error) · internal stress releasing as the cut opens · freehand
   cutting · misaligned fence · dull blade · standing in line with
   the cut
⚠️ THE CONTROLS THAT WORK
   ⚠️ RIVING KNIFE — ⚠️ the single most effective device; it moves
      with the blade and keeps the kerf open
   ⚠️ Blade height just above the stock
   ⚠️ Push stick past the blade; never freehand
   ⚠️ ⚠️ STAND OUT OF THE LINE OF FIRE
   ⚠️ Crosscut with a sled or mitre gauge, NEVER against the fence
   ⚠️ Support long or wide stock; use outfeed
   ⚠️ Blade guard on when the cut allows it
⚠️ ACTIVE INJURY MITIGATION (AIM) — ⚠️ flesh-detection systems that
   stop and drop the blade on contact. ⚠️ They address CONTACT and
   do NOT prevent kickback (§27.1)
```

## §10. Joinery Technique

**⚠️ The engineering of joints is covered in a materials/furniture reference; this is the
EXECUTION.**
```
⚠️ THE UNIVERSAL PRINCIPLE  ⚠️ cut to the line on the SHOW side,
   and leave the fit to paring. ⚠️ You can remove material; you
   cannot add it
⚠️ MORTISE AND TENON  ⚠️ cut the MORTISE FIRST, then fit the tenon
   to it — it's far easier to trim a tenon than to enlarge a mortise
⚠️ DOVETAILS  ⚠️ cut one, MARK the other FROM IT (§5's transfer rule).
   Tails-first or pins-first is a preference, not a correctness question
⚠️ HALF-LAPS and BRIDLES  simple, strong, forgiving — start here
⚠️ HOUSINGS/DADOES  ⚠️ router with a guide, or saw and chisel
⚠️ FIT  ⚠️ a joint that needs a mallet to assemble dry will split
   when glue swells the fibres. Firm hand pressure is the target
```
**⚠️ Test pieces**: ⚠️ **set up on scrap of the same thickness, every time.** **The setup is
where errors live, and scrap is cheaper than stock.**

---

## §11. Glue-Ups

**⚠️ The most stressful ten minutes in woodworking, because it's timed.**
```
⚠️ DRY FIT EVERYTHING FIRST, with clamps, and rehearse the sequence
⚠️ ⚠️ OPEN TIME is the constraint — ⚠️ PVA gives you minutes.
   ⚠️ For complex assemblies use slow-set or hide glue, or break
   the glue-up into STAGES
⚠️ CLAMPING PRESSURE  ⚠️ even, and enough to close the joint — but
   ⚠️ a joint that needs heavy clamping to close is cut wrong and
   will be under permanent stress
⚠️ CAULS and clamping blocks distribute pressure and protect surfaces
⚠️ CHECK SQUARE AND WIND before the glue sets — ⚠️ measure diagonals
⚠️ SQUEEZE-OUT  ⚠️ remove it, and note that dried glue BLOCKS FINISH,
   producing pale patches you won't see until it's too late
```
**⚠️ Long grain to long grain glues stronger than the wood; end grain glues poorly** —
⚠️ **which is why joints exist to create long-grain contact and mechanical interlock.**

---

## §12. Wood Finishing

**⚠️ Surface preparation is most of the result** — ⚠️ **sand progressively without skipping
grits, or plane and scrape (§6), which is faster and better where the grain allows.**
**⚠️ Raise the grain deliberately with a damp cloth before water-based finishes.**
**⚠️ Finish families** (covered more fully in a furniture reference): ⚠️ **film finishes
(shellac, lacquer, varnish/polyurethane, water-based) sit on top and protect; penetrating
finishes (oils, oil-varnish blends) soak in and are easy to repair; wax is a maintenance
coat.**
**⚠️ Practical**: ⚠️ **blotch-prone woods (pine, cherry, maple) need a conditioner or
shellac washcoat before stain; test on offcuts from the same board; thin coats beat thick
ones; and dust control during drying matters more than technique.**
**⚠️ SAFETY**: ⚠️ **oily rags spontaneously combust — spread flat or submerge in water in a
sealed metal container.** **⚠️ Solvent vapour needs ventilation, and some finishes need a
cartridge respirator, not a dust mask.**
