Campaign 26: Forge the Iron
The Complete Blacksmithing, Metalwork, and Forge Craft Guide
A Sovereignty Module of the Practitioner Community
Preamble
The blacksmith was the most essential craftsperson in every civilization for 5,000 years. The smith made the tools that built the houses, tilled the fields, shod the horses, armed the defenders, and repaired everything that broke. When a community lost its smith, it lost its ability to sustain itself. Industrial manufacturing has made the individual smith seem obsolete, but the knowledge of working metal by hand is the foundation of all manufacturing, all repair, and all self-sufficiency. A person who can forge, weld, and shape metal can make or fix almost anything. This campaign teaches you to build a forge from scrap, work steel with basic tools, and produce the essential items that every homestead and community needs.
Part I: The Forge
Chapter 1: Building a Forge
Forge Types:
| Forge Type | Cost | Fuel | Best For | Difficulty |
|---|---|---|---|---|
| Brake drum forge | $20-50 (scrap) | Charcoal or coal | Beginners, small work, knives, hooks, tools | Easy to build |

| Ash dump | Pipe cap with hole | Clean out ash from bottom |
Chapter 2: Essential Tools
The Starter Toolkit:
| Tool | Purpose | Cost (New) | Alternative |
|---|---|---|---|
| Anvil (or substitute) | Shaping surface | $100-500 | Railroad track section ($20-50), large sledgehammer head |
| Cross-peen hammer (2-3 lbs) | Primary shaping tool | $20-40 | Any hammer works to start |
| Tongs (flat jaw, V-bit) | Holding hot metal | $20-40 per pair | Vise-grip pliers (temporary) |

Chapter 3: Fuel and Fire Management
Fuel Comparison:
| Fuel | Temperature | Cost | Availability | Notes |
|---|---|---|---|---|
| Lump charcoal (hardwood) | 2,000-2,400°F | $15-25 per 20 lbs | Hardware stores, make your own | Clean burning, easy to start, good for beginners |
| Bituminous coal | 2,500-3,000°F | $200-400 per ton | Coal suppliers, online | Traditional fuel, hotter, produces clinker, needs coke-making |
| Propane | 2,300°F (forge) | $3-4 per gallon | Gas stations, hardware stores | Clean, consistent, easy to control |
| Homemade charcoal | 2,000-2,400°F | Free (wood + time) | Make from hardwood | Burn hardwood in restricted air (retort method) |
Fire Management:
| Fire State | Appearance | Temperature | Use |
|---|---|---|---|
| Oxidizing (too much air) | Bright, roaring, sparking | Very hot but scaling | Avoid — burns metal, creates excessive scale |
| Neutral (balanced) | Steady glow, minimal sparking | Ideal working heat | Best for most forging work |
| Reducing (less air) | Quiet, deep glow | Slightly cooler | Best for forge welding, prevents oxidation |
Chapter 4: Heat Colors and Temperature
The Smith's Color Guide:
| Color | Temperature (°F) | What You Can Do |
|---|---|---|
| Black heat | Below 900°F | Nothing — metal will crack if hammered |
| Dark red | 900-1,050°F | Light bending of thin stock |
| Cherry red | 1,050-1,175°F | General forging begins — bending, light drawing |
| Bright cherry | 1,175-1,300°F | Good working heat — most forging operations |
| Orange | 1,300-1,500°F | Excellent working heat — heavy drawing, upsetting |
| Light orange/yellow | 1,500-1,700°F | Maximum working heat — forge welding begins |
| Yellow | 1,700-1,900°F | Forge welding temperature |
| White | 1,900°F+ | Burning — metal is being destroyed. Remove immediately. |
Part II: Fundamental Techniques
Chapter 5: The Six Basic Operations
| Operation | What It Does | How To Do It |
|---|---|---|
| Drawing out | Makes metal longer and thinner | Heat to orange. Hammer on the far edge of the anvil, rotating 90° between strikes. |
| Upsetting | Makes metal shorter and thicker | Heat the end. Strike the cold end against the anvil face (or hammer the hot end). |
| Bending | Changes the angle of the metal | Heat the bend point. Place over anvil edge or in vise. Hammer to desired angle. |
| Punching | Creates a hole through the metal | Heat to bright orange. Place punch on metal over pritchel hole. Strike through. |
| Twisting | Rotates the metal along its axis | Heat the section to twist. Clamp one end in vise. Twist with wrench or tongs. |
| Forge welding | Joins two pieces of metal by hammering at welding heat | Heat both pieces to yellow/white. Apply flux (borax). Place together on anvil. Strike firmly and quickly. |
Chapter 6: First Projects
Project Progression (Beginner to Intermediate):
| Project | Skills Practiced | Difficulty | Time |
|---|---|---|---|
| S-hook | Drawing, bending, scrolling | Beginner | 15-30 min |
| J-hook (wall hook) | Drawing, bending, punching | Beginner | 20-40 min |
| Bottle opener | Drawing, bending, punching, finishing | Beginner+ | 30-60 min |
| Fireplace poker | Drawing, bending, upsetting, handle making | Intermediate | 1-2 hours |
| Knife (simple) | Drawing, beveling, heat treating, handle fitting | Intermediate | 3-6 hours |
| Tongs | Drawing, bending, riveting, fitting | Intermediate+ | 2-4 hours |
| Garden hoe | Drawing, punching, welding handle socket | Intermediate | 2-3 hours |
| Axe/hatchet | Drawing, punching (eye), forge welding, heat treating | Advanced | 4-8 hours |
Chapter 7: Heat Treatment
The Three Steps of Heat Treatment:
| Step | What It Does | How To Do It |
|---|---|---|
| Hardening | Makes steel hard (but brittle) | Heat to critical temperature (non-magnetic, cherry red). Quench in oil (for most carbon steels) or water (for some steels). |
| Tempering | Reduces brittleness while retaining hardness | After hardening, clean the steel bright. Heat slowly and watch for temper colors. Quench when desired color appears. |
| Annealing | Makes steel soft (for filing, drilling, shaping) | Heat to critical temperature. Let cool as slowly as possible (bury in vermiculite or ash). |
Temper Color Guide:
| Color | Temperature (°F) | Hardness | Best For |
|---|---|---|---|
| Light straw | 400°F | Very hard | Razors, engraving tools, surgical instruments |
| Dark straw | 450°F | Hard | Knives, chisels, plane blades |
| Bronze/brown | 500°F | Medium-hard | Axes, wood chisels, punches |
| Purple | 530°F | Medium | Springs, screwdrivers, cold chisels |
| Blue | 570°F | Tough (less hard) | Saws, springs, swords |
| Light blue/gray | 600°F+ | Soft and tough | Springs that need maximum flexibility |

| Nails and fasteners | Mild steel rod | Construction, repair |
| Hinges and hardware | Mild steel flat bar | Doors, gates, furniture |
Chapter 9: The Practitioner Forge Reference Card
SAFETY FIRST: Eye protection always. Leather gloves and apron. Never quench near your body. Hot metal looks the same as cold metal. Assume everything in the shop is hot.
HEAT COLORS: Black = do not hammer. Cherry red = start forging. Orange = best working heat. Yellow = forge welding. White = burning.
SIX OPERATIONS: Draw out (longer/thinner). Upset (shorter/thicker). Bend. Punch. Twist. Forge weld.
HEAT TREATMENT: Harden (heat to non-magnetic, quench in oil). Temper (reheat to color, quench). Anneal (heat, cool slowly).
TEMPER COLORS: Straw = knives/razors. Bronze = axes/chisels. Purple = springs/punches. Blue = saws/swords.
FIRST FORGE: Brake drum + pipe + hair dryer + charcoal. Total cost: $20-50. You can be forging today.
REMEMBER: The smith who can make tools can make anything. Start with an S-hook. End with an axe. The forge is the foundation of all self-sufficiency.
