The short answer: To clean and maintain wooden saw horses, regularly remove dust and debris, wipe with a damp cloth, dry thoroughly, sand any rough spots, and apply a protective finish like wood oil or sealant. Store them in a dry place, inspect for damage before each use, and replace worn parts promptly. This routine prevents rot, splinters, and structural failure, extending their life significantly.
Wooden saw horses are workhorses in any workshop, but they are constantly exposed to dirt, moisture, and stress. Unlike metal or plastic, wood is porous and can absorb moisture, leading to warping, cracking, and rot. Regular cleaning and maintenance not only keep them looking good but also ensure they remain safe and stable for years. A well-maintained sawhorse can last decades, while a neglected one might fail at the worst moment.
Start by removing any debris, sawdust, or loose dirt. Use a stiff brush or a shop vacuum to clean the surface and crevices. Then, wipe down the wood with a damp cloth and mild soap (like dish soap) to remove grease or stains. Avoid soaking the wood; just damp is enough. Rinse with a clean damp cloth and immediately dry with a towel or let it air dry in a well-ventilated area. For stubborn sap or adhesive, use a putty knife or fine sandpaper, but be careful not to gouge the wood.
Before each use, give your saw horses a quick check. Look for cracks, splits, loose joints, or wobbly legs. If you find any, assess whether it is a DIY fix or if you need to replace the sawhorse. For minor cracks, you can clamp and glue them with wood glue. For loose screws or bolts, tighten or replace them. If the wood is severely rotted or split, it is time to retire that unit. Remember, safety first: a broken sawhorse can cause accidents.
To protect against moisture and wear, apply a wood finish. Options include boiled linseed oil, tung oil, or a clear wood sealer. These penetrate the wood and create a barrier. Use a brush or rag to apply a thin coat, let it soak in, then wipe off excess. Allow it to dry completely before stacking. Reapply every few months or when the wood looks dry. Also, consider adding rubber feet or non-slip pads to prevent slipping and reduce wear on the legs.
How you store your saw horses is crucial. Keep them in a dry, well-ventilated area, preferably off the ground on a rack or hooks. If you must store them outside, cover them with a tarp or plastic sheeting and elevate them to avoid ground moisture. Avoid leaving them in direct sunlight for long periods, as UV rays can dry out and crack the wood. If you have a garage or shed, that is ideal. Proper storage prevents warping and rot, ensuring they are ready when you need them.
Knowing when to stop repairing and replace is key. If a sawhorse has extensive rot, many cracks, or structural instability that you cannot fix securely, it is time for a new one. Also, if you have repaired it multiple times and it keeps failing, replacing is more cost-effective. When shopping for replacements, consider quality and durability. Check out this guide to the best saw horses for options that might last longer and require less maintenance.
One of the most overlooked aspects of buying or building wooden saw horses is getting the size and height right for your typical tasks. Standard sawhorses come in heights ranging from about 24 to 36 inches. The ideal height depends on what you plan to do. For general carpentry, a height that brings the work surface to roughly mid-thigh or waist level is comfortable. If you will be cutting large sheets of plywood, a lower height (around 24 to 28 inches) gives you more leverage and control. For detailed work like sanding or planing, a taller sawhorse (30 to 36 inches) reduces back strain. Also consider the top surface: a wider top (at least 2×4 inches) provides more support and stability. If you often work with long boards, look for sawhorses with a longer top (36 to 48 inches) to prevent tipping. Many store-bought models list weight capacity, which is a good indicator of sturdiness. For heavy loads, choose a pair rated for at least 500 pounds each. If you are building your own, use thicker lumber (2×6 or 4×4 legs) for extra strength. Remember that the height of the sawhorse plus the thickness of your workpiece determines your working height, so measure before you commit. Adjustable sawhorses can be a good compromise if you need versatility, but they may have more joints to maintain. Finally, think about storage: taller sawhorses take up more vertical space, so if your workshop is small, a lower profile might be easier to stash.
Even well-intentioned owners make mistakes that shorten the life of their saw horses. Here are the most common pitfalls and how to avoid them. First, over-tightening screws or bolts. Wood expands and contracts with humidity, and overtightening can crush fibers or strip holes. Use washers and tighten snugly, not with extreme force. Second, ignoring the early signs of rot. A small soft spot can spread quickly; if you catch it early, you can dry the wood and apply a fungicide, but if you wait, the whole leg may need replacing. Third, using the wrong finish. Some finishes, like polyurethane, form a film that can crack and peel if the wood moves. Penetrating oils are more forgiving for sawhorses that flex under load. Fourth, storing them on a concrete floor. Concrete wicks moisture, so always elevate them on a rack or blocks. Fifth, using them as a workbench for heavy pounding. Saw horses are designed for support, not as an anvil; repeated impact can loosen joints. Sixth, neglecting the feet. The bottom of the legs is most prone to moisture and wear. Add rubber caps or treat the end grain with extra sealer. Seventh, cleaning with harsh chemicals. Bleach or solvents can damage wood fibers; stick with mild soap and water. Eighth, forgetting to check for splinters. Run your hand along the top and legs before each use; a splinter can cause a nasty cut. Ninth, leaving them in the rain even for a short time. A sudden shower can soak into unprotected end grain. Tenth, assuming pressure-treated wood is maintenance-free. It still needs cleaning and sealing to prevent cracking. By avoiding these mistakes, you will get many more years of service from your saw horses.
While wooden saw horses are traditional and repairable, there are times when an alternative might better suit your needs. Metal sawhorses, often made of steel or aluminum, are heavier but resist rot and moisture. They are a good choice if you work outdoors or in damp environments. However, they can rust if scratched, and they are not as easy to repair. Plastic sawhorses are lightweight and inexpensive, but they may become brittle in cold weather and cannot support as much weight. Folding metal or plastic sawhorses are convenient for tight storage, but their hinges and locking mechanisms can wear out. If you need portability, consider a folding design, but check the weight capacity. Another alternative is a portable workbench or a pair of sturdy trestles. These can replace sawhorses for some tasks but are often bulkier. When should you not buy wooden saw horses? If you need to set up and tear down daily on a job site, a lightweight folding metal or plastic option may be more practical. If you work primarily with heavy timber, you might need specialized heavy-duty stands. If you have limited storage and only occasional use, a folding plastic sawhorse might suffice. However, for a permanent workshop setup where you value stability, repairability, and the ability to customize, wooden saw horses remain an excellent choice. They can be built to any height, reinforced as needed, and repaired with basic tools. Ultimately, the decision depends on your work environment, frequency of use, and willingness to maintain them. Wooden sawhorses reward care with decades of service, but if you know you will not maintain them, a low-maintenance alternative might be wiser.
Q: Can I use pressure-treated wood for saw horses to avoid rot?
A: Yes, pressure-treated lumber resists moisture and insects, but it still needs cleaning and occasional sealing. However, it can be heavier and may have chemicals, so consider your usage.
Q: How often should I apply a protective finish?
A: It depends on usage and environment. For indoor use, every 3-6 months is fine. For outdoor or heavy use, check monthly and reapply when water no longer beads on the surface.
Q: Is it okay to leave my wooden saw horses outside?
A: It is not ideal, but if you must, use a waterproof cover and elevate them. Even then, they will deteriorate faster than indoor storage. Bring them in when not in use for maximum longevity.
