Improvised Fasteners: Lashing, Pegs, and Wedges

When You Have No Hardware

Nails, screws, and bolts are everywhere until they're not. Extended grid-down scenarios, wilderness construction, and primitive skills all require the ability to join materials without hardware. The joinery methods used by pre-industrial builders — lashing, pegging, wedging, and binding — produce structures that last for generations when executed correctly.

These are not backup methods. They are primary methods that simply require different skills.

Lashing

Lashing is the binding of two or more poles or members together using cordage. Correctly executed, it creates rigid, load-bearing joints without any hardware.

Square Lashing

Joins two poles that cross at roughly right angles. Used for grid structures, raft construction, shelter frames, and furniture.

Test: The joint should not twist or shift under moderate force. If it rotates, the frapping turns were insufficient or too loose.

Diagonal Lashing

For poles that cross at angles other than 90°, or when you want to resist twisting specifically. Common in diagonal bracing.

Shear Lashing

Joins two poles end-to-end to extend their length, or joins two poles that will be spread apart (like an A-frame).

Tripod Lashing

Creates a self-supporting three-legged frame.

Wooden Pegs and Dowels

Pegs are the nail of primitive construction. A wooden peg driven into a pre-drilled or bored hole holds mortise and tenon joints, secures planks, and pins lashings in place.

Wood Selection

Peg wood needs to be hard and relatively straight-grained:

• Dry hardwood: Oak, hickory, locust, ash. Dry wood shrinks into a tight fit as the surrounding green wood dries.
• Avoid: Softwoods (pine, fir) for load-bearing pegs; they compress and pull through. Knotty or twisting-grain wood splits when driven.

The classic technique: bore or burn a hole in green wood, drive a dry hardwood peg. As the green wood dries, it shrinks around the dry peg and locks it.

Carving Pegs

A simple peg is a cylinder of consistent diameter:

1. Split a section of straight-grained hardwood to a rough square section slightly larger than the desired diameter
2. Whittle or carve to a consistent round cross-section using a knife
3. Taper the leading end slightly to make driving easier
4. The peg should require moderate force to drive — it shouldn't fall in freely or split the wood when driven

Boring Holes Without a Drill

Burning: Heat a nail, wire, or pointed metal rod in coals until red, then press into the wood and rotate. Produces a clean, consistent hole. Reheating the rod multiple times deepens the hole gradually.

Primitive bow drill (for wood): The fire bow drill can bore holes in wood — the same tool used for fire starting bores into a flat fireboard surface if pressed harder and longer.

Carved awl: A hardwood or bone awl point, twisted under pressure, works through softer woods. Slow, but effective for small-diameter pegs.

Wedges

A wooden wedge is one of the six simple machines and one of the most useful primitive fasteners. Wedges lock joints, split wood, and tension lashings.

Splitting Wood with Wedges

The log-splitting wedge is driven into an end grain crack or a starter kerf and driven deeper with a maul or heavy stone. As the wedge advances, the crack propagates through the grain.

Technique:

• Find or create a starter crack (knot holes, end grain checks, or a kerf cut with a saw or stone blade)
• Drive the wedge with controlled, centered blows — off-center blows skew the split
• Use multiple wedges for long splits: set the first wedge, then leapfrog them down the split

Wedges as Fasteners (Fox Wedging)

Fox wedging locks a tenon in a mortise permanently:

1. Create a tenon (peg on the end of one member) and a mortise (hole in the other)
2. Cut a slot down the center of the tenon end
3. Insert a small wedge in the slot (the fox wedge)
4. Drive the tenon into the mortise — as it bottoms out, the mortise walls force the wedge deeper, spreading the tenon and locking it

This joint cannot be disassembled without destroying it. Used in furniture and handle construction.

Wedge-Tightened Axe Handles

The traditional axe handle is kerf-cut at the top and wedged after driving through the eye:

1. Drive the handle through the axe eye from the bottom
2. The eye is tapered — wider at top than bottom — so the handle locks as it's driven
3. Cut one or two kerfs in the top of the handle
4. Drive wooden wedges (and optionally a metal wedge) into the kerfs
5. Trim flush and check that the head is tight — no wobble, no ring gap

Rawhide Binding

Wet rawhide is one of the most effective primitive fasteners. Applied wet, it shrinks to iron tightness as it dries.

Applications

• Axe hafting: Wrapped around the handle-eye junction, shrinks to lock the head
• Tool handles: Wrapped over a split handle gripping a blade or point
• Repair binding: Cracked handles, broken tool shafts
• Lashing tension enhancement: Rawhide lashing over cordage lashing adds permanent tension

Technique

1. Soak rawhide in water until pliable — at least 15-30 minutes for thin strips, longer for thick
2. Dry-fit the joint before applying rawhide
3. Wrap tightly — the goal is tension even when wet, so that when it shrinks, the joint is extremely tight
4. Overlap each wrap slightly to create a consistent layer
5. Tie off the end with a square knot, then tuck it under adjacent wraps
6. Let it dry completely — usually 24-48 hours in dry conditions
7. Do not disturb while drying — moving a drying rawhide joint reduces final tension

The fully dry rawhide is hard as plastic and requires cutting to remove.

Toggle Fasteners

A toggle is a short crosspiece secured through a loop of cordage that prevents the loop from pulling free. The simplest button in the world.

Making a toggle closure:

1. Create a loop of cordage — sized to just fit over the toggle
2. Attach the loop to one side of what you're closing (a bag, a garment edge)
3. Drill or cut a small hole or loop in the other side — the toggle anchor
4. The toggle (a short stick, bone, or carved piece) threads through the anchor loop
5. When worn or in tension, the toggle is perpendicular to the cordage pull and holds
6. To release, orient the toggle parallel and pull through

Toggle fasteners appear in every traditional culture because they work, require no hardware, and are replaceable from any handy stick or bone.
