The transformation of animal hide into a robust and reliable stretcher is a practice deeply rooted in survival and preparedness. It is a testament to human ingenuity, utilizing readily available resources to create essential equipment. This article provides a comprehensive, step-by-step guide to this intricate process, covering everything from selecting the right hide to the final assembly of a durable stretcher.
Securing and Preparing the Animal Hide
The foundation of any successful hide-based endeavor lies in the quality and preparation of the raw material. For a stretcher, a substantial piece of hide is required, capable of bearing significant weight and withstanding the rigors of transport.
Choosing the Appropriate Animal Hide
The selection of the animal from which the hide is sourced is paramount. Larger game animals, such as deer, elk, or even cattle, are ideal candidates due to the size and strength of their hides. A hide from a mature animal will generally be thicker and more durable than that of a younger one. The area of the hide is also important; the back and flanks typically offer the most expansive and uniformly thick sections, which are desirable for a stretcher. Smaller hides can be pieced together, but this adds complexity and potential weak points. When considering the source, ethical hunting practices and the proper processing of the animal are crucial to ensure the hide’s integrity. A hide that has been poorly flayed or inadequately cooled can degrade quickly, making it unsuitable for its intended purpose. The presence of scars or holes should be noted, as these may require reinforcement or careful placement to avoid compromising the stretcher’s strength.
Initial Hide Processing: Flaying and Cleaning
The process begins immediately after the animal has been harvested. Proper flaying is essential to remove the hide with minimal damage to its surface. A sharp knife is required, and the flayer should aim to cut close to the hide, avoiding deep gouges into the flesh or fat layer. The goal is to remove the hide in one continuous piece if possible. Once removed, the hide will be covered in a significant amount of flesh, fat, and connective tissue. This material must be meticulously removed. This “scrapping” or “fleshing” process can be done using a fleshing beam and a dull scraping tool, or a sharp knife if done with extreme care. A fleshing beam can be a smooth, rounded log or a specialized frame that allows the hide to be stretched taut over it while working. The objective is to create a clean, uniform surface on the flesh side of the hide. Any remaining tissue will rot and can lead to the deterioration of the hide, weakening the final stretcher. Thorough cleaning also involves removing any blood or initial contamination. Rinsing the hide with clean water, if available, can help in this initial stage.
Preserving the Hide: Salting or Drying
Before significant work can begin on the stretcher, the hide must be preserved to prevent decomposition. There are two primary methods for this: salting and drying. Salting is a highly effective method for preserving hides and is often preferred as it helps to retain some of the hide’s natural oils, making it more pliable once processed. To salt a hide, it should be spread out, flesh side up, and liberally covered with coarse salt. Every part of the flesh side, including edges and any remaining thin spots, must be thoroughly coated. The hide can be folded onto itself, flesh to flesh, to ensure all surfaces are in contact with the salt. It should then be placed in a cool, dry location, away from direct sunlight and moisture. The salt will draw out moisture and any residual blood. This process can take several days to a week, depending on the thickness of the hide and the ambient temperature. The salt should be scraped off and reapplied if it becomes saturated with liquid.
Drying is another viable method, particularly in arid environments. The hide is stretched taut, flesh side out, using a frame, pegs, or by tying it to trees. It is crucial that the hide is secured in a way that allows air to circulate freely around it, preventing mildew. In humid climates, drying can be challenging and may require artificial heat or constant turning to prevent spoilage. The hide is considered dry when it is stiff and brittle. While drying is simpler in terms of materials, it can result in a more brittle hide that requires additional softening steps later. Regardless of the preservation method, the hide must be completely treated before moving on to the construction phase.
Turning animal hide into a stretcher is an ancient practice that showcases the resourcefulness of various cultures in utilizing available materials for practical purposes.

Preparing the Hide for Stretcher Construction
Once the hide is preserved and ready for processing, it needs to undergo further steps to become a suitable material for the stretcher. This involves softening, thinning, and potentially curing.
Softening and Pounding the Hide
After salting or drying, the hide will likely be stiff and somewhat brittle, especially if dried. To make it pliable enough to work with and to create a strong, flexible material for the stretcher, it needs to be softened. This is traditionally achieved through pounding. The hide can be stretched over a smooth, hard surface, such as a large rock or a wooden beam, and then pounded with a blunt instrument. This could be a wooden mallet, a smooth stone, or even the heel of one’s foot. The pounding action breaks down the collagen fibers, making the hide more supple and reducing its stiffness. This process needs to be systematic, covering the entire surface of the hide evenly. As the hide is pounded, it will become noticeably softer and more flexible. It is important to continue pounding until a desired level of pliability is reached. Some cultures also utilize a process of chewing the hide to soften it, particularly for smaller items, but this is less practical for the large surface area of a stretcher.
Thinning and Shaping the Hide
Depending on the thickness of the original hide and the desired properties of the stretcher, further thinning may be necessary. This can be achieved through a process of scraping, similar to fleshing, but with a finer scraping tool and a more controlled pressure. The goal is to remove excess thickness from the flesh side without compromising the structural integrity of the hide. This thinning process also helps to ensure a more uniform thickness across the entire piece of hide, which is important for even stretching and load distribution. The hide should be shaped into a rectangular or square form, depending on the intended design of the stretcher. Any excess material around the edges can be trimmed off. It is advisable to leave a slightly larger piece than initially anticipated, as some trimming may occur during the construction and final assembly. The goal is to have a single, large, pliable piece of hide that can form the main body of the stretcher.
Tanning for Enhanced Durability (Optional but Recommended)
While a properly preserved and softened hide can be used for a stretcher, the durability and longevity can be significantly enhanced through a tanning process. Tanning stabilizes the hide’s proteins, preventing it from rotting, becoming stiff when dry, and developing an unpleasant odor. There are several traditional tanning methods, but a common and effective one is using brain tanning. Animal brains contain fats and oils that, when worked into the hide, create a supple and water-resistant material. The hide is soaked and then pounded again while being saturated with a mixture of water and emulsified brain matter. Another method involves using natural tannins derived from tree bark, such as oak or willow. The hide is soaked in a solution of water and ground bark. This process can take a considerable amount of time, often days or weeks, and requires repeated soaking and working of the hide. While more labor-intensive, tanning produces a much more resilient and long-lasting material, making the stretcher more reliable in various conditions.
Constructing the Stretcher Frame
A sturdy frame is crucial to support the hide and provide the structure for the stretcher. The choice of materials and the design of the frame will directly impact the stretcher’s strength and portability.
Selecting Appropriate Frame Materials
The ideal materials for the stretcher frame are strong, lightweight, and readily available. Wood is the most common and practical choice. Straight, seasoned branches or poles are preferred. Hardwoods like oak, ash, or hickory will offer superior strength and durability compared to softer woods. The diameter of the poles should be substantial enough to bear weight without bending or breaking – typically 1.5 to 3 inches in diameter, depending on the size of the stretcher and the expected load. The poles should be as straight as possible to create a clean, even frame. If naturally straight poles are not available, they can be straightened through steaming and bending, although this is a more advanced technique. For portability, consider if the frame needs to be collapsible. In such cases, joints and fastening methods become critical. Natural cordage, such as rawhide strips or strong plant fibers, can be used for lashing, but for a permanent frame, wooden pegs or specialized joinery might be considered.
Designing and Assembling the Basic Frame
The simplest and most effective stretcher frame is a rectangular or square shape, formed by four main poles. Two longer poles will form the sides, and two shorter poles will create the crossbars at the ends. The length and width will depend on the size of the hide and the intended use. For a standard adult stretcher, a length of 6 to 7 feet and a width of 2 to 2.5 feet is typical. The poles are joined at the corners to create a rigid structure. Traditional lashing techniques are highly effective here. This involves wrapping strong cordage (such as prepared rawhide strips or natural fiber rope) tightly around the joint, securing it in a knot that will not slip under tension. A square lashing or a diagonal lashing can be used. For maximum strength, the lashing should be done with care, ensuring each wrap is tight against the previous one. Alternatively, if tools and resources allow, the poles can be joined using mortise and tenon joints or by drilling holes and securing them with wooden dowels or pegs. The key is to create a frame that is strong, stable, and free of significant wobble.
Reinforcing the Frame for Load Bearing
Once the basic frame is assembled, reinforcement is essential to ensure it can withstand the stresses of carrying an injured person. The corners are the most critical points, so they should be particularly well-lashed or joined. Additional cross bracing can be added if necessary, especially for larger stretchers or those intended for rough terrain. A crossbar running midway along the length of the stretcher can prevent the side poles from bowing outwards under the weight of the hide and the load. Similarly, diagonal braces can be incorporated to prevent racking – the tendency of the frame to distort from its rectangular shape into a parallelogram. These reinforcements should be made from similar strong materials and secured with the same robust techniques used for the main frame. The overall goal is a frame that feels solid and rigid, with no give or looseness in its structure. Inspecting the frame thoroughly for any signs of weakness before attaching the hide is a crucial final step in this phase.
Attaching the Hide to the Frame
With the frame constructed and the hide prepared, the next critical step is to securely attach the hide to form the functional stretcher. This requires careful tensioning and fastening to ensure the hide is taut and will hold weight effectively.
Positioning the Hide on the Frame
The prepared hide should be laid out flat. The frame is then placed on top of the hide, typically centered. The edges of the hide should extend beyond the frame on all sides, providing enough material to wrap around and secure to the frame poles. The orientation of the hide is important; the grain of the hide should ideally run along the length of the stretcher, as this generally provides greater tensile strength. If the hide has a noticeably thicker or thinner side, the thicker side should generally face upwards, as this will be the side the patient rests on, offering more comfort and support. Ensure the hide is positioned as evenly as possible to avoid creating uneven tension or stress points later in the process.
Securing the Hide: Lacing and Pegging
There are several methods for attaching the hide to the frame. The most common and effective is lacing. This involves creating a series of holes or slits along the edges of the hide, spaced evenly apart. These holes are then used to lace the hide to the frame poles. Strong cordage, such as prepared rawhide strips, paracord, or natural fiber rope, is used for lacing. The lacing should be done in a continuous pattern, much like tying shoelaces, pulling the hide taut as you go. A common lacing pattern is a continuous loop around the perimeter. Alternatively, the edges of the hide can be folded over the frame poles and then secured by pegging. Small, sharpened wooden pegs are driven through the folded hide and into the frame poles, effectively pinning the hide in place. This method is faster but may be less secure than lacing, especially under significant load. For maximum security, a combination of lacing and pegging can be employed.
Achieving Optimal Tension for Load Bearing
Achieving the correct tension in the hide is paramount for the stretcher’s functionality. The hide needs to be taut enough to support weight without sagging excessively, but not so tight that it tears or strains the frame. As the hide is laced or pegged, it should be pulled firmly. If using rawhide, it will shrink and tighten as it dries, so it’s important to account for this. If the hide is still slightly damp, it will tighten considerably upon drying. The goal is a drum-like tautness. Walk around the stretcher, pressing down on different areas to feel for any significant give. Adjust the lacing or pegging as needed to distribute the tension evenly across the entire surface. Ensure there are no loose areas or wrinkles that could create pressure points or weaken the structure. The hide should be stretched uniformly, creating a smooth, supportive surface.

Once the hide is securely attached, a few finishing touches can enhance the stretcher’s usability and longevity. Proper maintenance will ensure its reliability for future use.
Adding Handles and Carry Straps
For ease of transport, handles are essential. These can be integrated into the frame itself or attached separately. Often, the extended ends of the frame poles can serve as handles, but this can be uncomfortable for long carries. More comfortable handles can be fashioned from stout rope or thick leather straps, secured firmly to the frame at strategic points, typically near the ends. These should be robust enough to bear the weight of the stretcher and its load. Alternatively, loops of strong cordage can be attached to the frame, allowing for multiple handholds or the attachment of larger carry straps for two or more people. Carry straps that go over the shoulders can distribute the weight more evenly, making transport less fatiguing, especially over longer distances. These straps should be made of strong, durable material and securely fastened to the stretcher’s frame.
Finishing and Weatherproofing
While the tanning process provides a degree of weatherproofing, further treatment can enhance the hide’s resistance to moisture and the elements. Natural oils or animal fats, such as tallow or bear grease, can be applied to the hide. These penetrate the fibers, offering protection against water absorption and helping to keep the hide supple. The fat should be worked into the hide thoroughly and then allowed to soak in. This process can be repeated for added protection. Avoid synthetic oils or petroleum-based products, as they can degrade natural hides over time. The wooden frame can also be treated with natural oils or resins to protect it from rot and insect damage. The aim is to create a stretcher that is durable in a variety of environmental conditions.
Storing and Maintaining the Stretcher
Proper storage is crucial for the longevity of any handmade item. The stretcher should be stored in a cool, dry place, away from direct sunlight and extreme temperatures. If possible, it should be hung to allow air circulation around it, preventing moisture buildup and the potential for mold or mildew. Before and after each use, the stretcher should be inspected for any signs of damage. Check the lacing, pegging, frame joints, and the hide itself for any tears, looseness, or signs of wear. Minor repairs can be made promptly to prevent them from becoming larger problems. If the stretcher gets wet, it should be allowed to dry naturally, away from direct heat, and then potentially re-oiled or waxed if necessary. Regular inspection and care will ensure that the animal hide stretcher remains a reliable and functional piece of equipment for years to come.
