## Complete Rope and Cordage: From Fiber to Rigging

Rope is civilization's connective tissue — it builds, lifts, secures, climbs, and rescues. This campaign covers fiber selection, cordage construction, splicing, rigging, and load calculations for every application.

### Chapter 1: Fiber Sources for Cordage

| Fiber | Breaking Strength | Rot Resistance | Flexibility | Availability | Best Use |
|---|---|---|---|---|---|
| Manila (abaca) | Very high | Good | Moderate | Tropical cultivation | Heavy rigging, mooring |
| Hemp | High | Good | Good | Temperate cultivation | General purpose, marine |
| Sisal | Moderate-high | Moderate | Stiff | Tropical/subtropical | Agriculture, baling |
| Cotton | Moderate | Poor | Excellent | Warm climate cultivation | Soft applications, sash cord |
| Jute | Low-moderate | Poor | Good | Tropical | Light binding, burlap |
| Linden bark (bast) | Moderate | Moderate | Good | Temperate forests (wild) | Emergency, primitive cordage |
| Nettle | High | Moderate | Good | Temperate (wild) | Fine cordage, fishing line |
| Yucca/agave | Moderate-high | Good | Stiff | Arid/subtropical | Desert cordage, sandals |
| Rawhide | Very high | Poor (if wet) | Low (dry) | Any (from animals) | Lashing, binding |
| Sinew | Very high | Moderate | Moderate | Any (from animals) | Bowstrings, sewing |

### Chapter 2: Cordage Construction

| Type | Strands | Twist Direction | Strength | Flexibility | Time to Make |
|---|---|---|---|---|---|
| Two-ply (simple) | 2 | S-twist (reverse lay) | Moderate | High | 1 ft/5 min |
| Three-strand (laid) | 3 | Z-twist strands, S-lay | High | Moderate | 1 ft/10 min |
| Four-strand (square) | 4 | Alternating | Very high | Low | 1 ft/15 min |
| Braided (8-strand) | 8 | Interlocked | High | Very high | 1 ft/20 min |
| Cable-laid | 3 ropes twisted together | Opposite to rope twist | Very high | Low | Requires finished rope |

Two-ply cordage (fastest field method): 1) Prepare fibers (strip, ret, or pound to separate). 2) Bundle fibers into two equal groups. 3) Twist one group clockwise (Z-twist) between fingers. 4) Wrap that twisted group counter-clockwise (S-direction) around the other. 5) Now twist the second group clockwise. 6) Wrap counter-clockwise around first. 7) Repeat — the opposing twists lock together. 8) Add new fibers by overlapping 2-3 inches into existing strand. 9) Result: cord that holds together under tension because twist fights untwisting.

Three-strand rope (standard): 1) Spin fibers into yarn (tight Z-twist). 2) Combine 3-20 yarns into strand (S-twist — opposite direction). 3) Lay three strands together (Z-twist — back to original direction). 4) Each reversal of twist direction locks the previous level in place. 5) Rope diameter and strength scale with number of yarns per strand.

### Chapter 3: Strength and Load Calculations

| Rope Diameter | Manila Breaking Strength | Safe Working Load (5:1) | Weight/100ft | Common Use |
|---|---|---|---|---|
| 1/4 inch | 600 lbs | 120 lbs | 1.5 lbs | Light lashing, clothesline |
| 3/8 inch | 1,350 lbs | 270 lbs | 3.5 lbs | General utility, tent lines |
| 1/2 inch | 2,650 lbs | 530 lbs | 5.5 lbs | Moderate lifting, rigging |
| 5/8 inch | 4,400 lbs | 880 lbs | 8 lbs | Heavy lifting, anchoring |
| 3/4 inch | 5,400 lbs | 1,080 lbs | 10.5 lbs | Construction, mooring |
| 1 inch | 9,000 lbs | 1,800 lbs | 16 lbs | Heavy construction, towing |
| 1.5 inch | 18,500 lbs | 3,700 lbs | 36 lbs | Ship mooring, heavy rigging |

Safety factors: Always divide breaking strength by safety factor to get working load. Minimum 5:1 for general use. 8:1 for life safety (climbing, rescue). 10:1 for overhead lifting of people. Knots reduce strength 25-50% (figure-8 loses 25%, bowline loses 35%, square knot loses 50%). Wet rope loses 10-15% strength. Aged/worn rope: inspect and retire when fibers are broken or rope is stiff.

### Chapter 4: Essential Knots and Hitches

| Knot | Purpose | Strength Retained | Difficulty | Untie After Load |
|---|---|---|---|---|
| Bowline | Fixed loop (won't slip) | 65% | Moderate | Easy |
| Figure-8 loop | Fixed loop (climbing) | 75% | Low | Moderate |
| Clove hitch | Attach to post/pole | 65% | Low | Easy |
| Taut-line hitch | Adjustable tension | 65% | Moderate | Easy |
| Sheet bend | Join two different ropes | 55% | Low | Easy |
| Trucker's hitch | Mechanical advantage tie-down | 65% | Moderate | Easy |
| Prusik | Slide-and-grip on rope | 65% | Moderate | Easy |
| Timber hitch | Drag logs/poles | 70% | Very low | Falls off when slack |
| Constrictor knot | Permanent binding | 60% | Low | Cannot untie (cut off) |
| Anchor bend | Attach to ring/anchor | 70% | Low | Moderate |

### Chapter 5: Splicing

| Splice Type | Purpose | Strength Retained | Difficulty | Time |
|---|---|---|---|---|
| Eye splice | Permanent loop in rope end | 90-95% | Moderate | 15-30 min |
| Short splice | Join two rope ends (thicker) | 85-90% | Moderate | 20-40 min |
| Long splice | Join two ropes (same diameter) | 85% | High | 30-60 min |
| Back splice | Prevent end from unraveling | 100% (no loop) | Low | 10-15 min |

Eye splice (three-strand rope): 1) Unlay 6-8 inches of rope end into three strands. 2) Form loop of desired size. 3) Tuck first strand under one strand of standing rope (against the lay). 4) Tuck second strand under next strand. 5) Turn over, tuck third strand under remaining strand. 6) Continue tucking each strand over-one-under-one for 3-5 full tucks. 7) Trim ends. 8) Result: permanent loop that retains 90-95% of rope strength (vs. 65% for bowline knot).

### Chapter 6: Rigging and Mechanical Advantage

| System | Mechanical Advantage | Rope Needed | Complexity | Max Practical Load |
|---|---|---|---|---|
| Single fixed pulley | 1:1 (direction change only) | 1x height | Very low | Rope's working load |
| Single movable pulley | 2:1 | 2x height | Low | 2x human pull |
| Block and tackle (2 pulleys) | 3:1 or 4:1 | 3-4x height | Moderate | 3-4x human pull |
| Compound (3+ pulleys) | 5:1 to 8:1 | 5-8x height | High | 5-8x human pull |
| Spanish windlass | 4:1 to 10:1 | Short rope + lever | Low | Limited by lever/rope |
| Capstan/windlass | 10:1 to 50:1 | Wrap around drum | Moderate | Very heavy loads |

### Reference Card

1. Opposite twists lock (Z-twist yarn, S-twist strand, Z-twist rope — each level locks the one below). 2. Safety factor 5:1 minimum (never load rope above 20% of breaking strength for general work). 3. Knots weaken rope (every knot reduces strength 25-50% — splice where possible). 4. Wet rope is weaker (10-15% strength loss when wet — account for this). 5. Inspect before every use (broken fibers, stiffness, discoloration = retire the rope). 6. Splice beats knot (90-95% strength retained vs. 55-75% for knots). 7. Pulleys multiply force (each additional pulley adds mechanical advantage — 4 pulleys = one person lifts 400 lbs). 8. Never stand under load (if rope fails, anything underneath dies — always stand clear).
