Sovereignty Module: Work the Hide

Complete Leather Working: From Raw Hide to Finished Goods
Leather provides clothing, footwear, containers, armor, belts, harness, and hundreds of essential items. This campaign covers brain tanning, bark tanning, and construction of finished leather goods.
Chapter 1: Hide Preparation
| Step | Action | Duration | Tools | Purpose |
|---|---|---|---|---|
| 1 | Flesh (remove meat/fat from inside) | 1-2 hours | Fleshing beam + dull blade | Prevents rot, allows penetration |
| 2 | Soak in water (rehydrate if dried) | 12-48 hours | Tub or stream | Softens hide for working |
| 3 | De-hair (lime soak or ash soak) | 3-7 days | Lime + water, or hardwood ash + water | Loosens hair for removal |
| 4 | Scrape hair off (grain side) | 1-3 hours | Fleshing beam + scraper | Clean surface for tanning |
| 5 | Rinse thoroughly | 1-2 hours | Running water | Remove all lime/ash |
| 6 | Membrane (scrape inner side smooth) | 1-2 hours | Fleshing beam + sharp scraper | Thin hide, even thickness |
| 7 | Wring out excess water | 30 minutes | Twist on stick or wring by hand | Prepare for tanning solution |
Chapter 2: Brain Tanning (Buckskin)
| Step | Action | Duration | Details |
|---|---|---|---|
| 1 | Prepare brain solution | 30 minutes | One animal's brain per hide. Mash in warm water until creamy. |
| 2 | Work brain solution into hide | 1-2 hours | Both sides, massage thoroughly. Every fiber must be saturated. |
| 3 | Fold and let sit overnight | 8-12 hours | Wrap in plastic or damp cloth. Brain penetrates fibers. |
| 4 | Wring out hide (twist on stick) | 30 minutes | Remove excess moisture |
| 5 | Stretch and work hide (CRITICAL) | 4-8 hours continuous | Pull, stretch, work over cable/stake. Must keep moving until COMPLETELY dry. |
| 6 | Smoke hide (both sides) | 30-60 minutes per side | Rotten wood smoke (not hot). Waterproofs and preserves. |
CRITICAL: Step 5 determines success or failure. If hide dries without being worked, it becomes stiff rawhide. You must continuously stretch and pull the fibers apart as moisture evaporates. This is exhausting physical labor for 4-8 hours straight. The result is butter-soft buckskin.
Chapter 3: Bark Tanning (Vegetable Tanning)
| Step | Action | Duration | Details |
|---|---|---|---|
| 1 | Prepare bark solution (tannin liquor) | 1-2 weeks | Oak, hemlock, or chestnut bark. Shred, soak in water. |
| 2 | Weak solution first (1-2% tannin) | 1-2 weeks | Submerge hide, move daily |
| 3 | Medium solution (3-5% tannin) | 2-4 weeks | Transfer hide to stronger solution |
| 4 | Strong solution (5-10% tannin) | 4-8 weeks | Final tanning. Hide turns brown through entire thickness. |
| 5 | Rinse and oil | 1 day | Wash, apply neatsfoot oil or tallow |
| 6 | Dry slowly (out of sun) | 3-7 days | Even drying prevents warping |
| 7 | Work/soften (stake or tumble) | 1-2 hours | Softens to desired flexibility |
Total time: 2-4 months. Result: firm, water-resistant leather ideal for belts, holsters, sheaths, soles, saddles.
Chapter 4: Leather Projects
| Project | Leather Type | Thickness | Skill Level | Tools Needed |
|---|---|---|---|---|
| Moccasins | Brain-tanned (soft) | 3-5 oz | Beginner | Needle, sinew/thread, knife |
| Belt | Bark-tanned (firm) | 8-10 oz | Beginner | Knife, punch, buckle |
| Knife sheath | Bark-tanned (firm) | 6-8 oz | Intermediate | Knife, needle, rivets, wet-molding |
| Water container | Brain-tanned + pitch lining | 4-6 oz | Intermediate | Needle, pine pitch |
| Boots | Bark-tanned sole + soft upper | Sole: 10-12 oz, Upper: 4-6 oz | Advanced | Last, awl, needle, welt |
| Saddle | Bark-tanned (firm) | 10-14 oz | Expert | Tree (frame), many tools |
| Armor (cuir bouilli) | Bark-tanned, hardened | 10-14 oz | Advanced | Mold, boiling water/wax |
Chapter 5: Stitching and Construction
| Stitch Type | Use | Strength | Appearance |
|---|---|---|---|
| Running stitch | Light items, temporary | Low | Simple line |
| Saddle stitch (two-needle) | All permanent seams | Very high | Even, professional |
| Cross stitch | Decorative + structural | High | X-pattern |
| Whip stitch | Edge binding | Moderate | Spiral around edge |
| Lacing (thong) | Heavy items, no needle needed | High | Visible lace pattern |
Thread: Waxed linen thread (strongest for hand sewing). Sinew (traditional, very strong when dry). Waxed polyester (modern, rot-proof). Always wax thread before sewing (beeswax) — reduces friction, prevents rot.
Chapter 6: Hardening Leather (Cuir Bouilli)
| Method | Temperature | Duration | Result | Use |
|---|---|---|---|---|
| Hot water (170-180°F) | Just below boiling | 10-30 seconds | Shrinks, stiffens | Armor, cases, cups |
| Hot wax immersion | 180-200°F | 30-60 seconds | Stiff, waterproof | Armor, bottles |
| Dry heat (oven) | 250-300°F | 5-15 minutes | Very hard, brittle | Armor plates |
| Cold molding (wet + form) | Room temperature | Dry on form (24-48 hours) | Moderately stiff, shaped | Holsters, cases |
WARNING: Overheating destroys leather permanently. Test on scraps first. Hot water method: dip briefly, form immediately while hot and pliable, hold shape until cool and dry.
Reference Card
- Brain tanning: one brain per hide. Work into fibers, let sit overnight, then stretch continuously 4-8 hours until dry. Smoke to waterproof.
- Bark tanning: 2-4 months in progressively stronger tannin solutions. Result: firm, water-resistant leather.
- De-hairing: soak in lime water (calcium hydroxide) or hardwood ash water for 3-7 days. Hair scrapes off easily.
- Saddle stitch: two needles, one thread. Strongest hand stitch. Use for all permanent seams.
- Wax all thread before sewing. Beeswax reduces friction, prevents rot, strengthens thread.
- Hardening: brief dip in 170-180°F water. Form immediately while hot. Holds shape when cool. Makes armor.
- Oil finished leather: neatsfoot oil or tallow. Prevents cracking, maintains flexibility. Re-oil annually.
- Thickness: 1 oz = 1/64 inch. Moccasins: 3-5 oz. Belts: 8-10 oz. Boot soles: 10-12 oz.
