Choosing the right material for your table saw sled runners is crucial to ensure smooth and accurate cuts.
When it comes to sled runners, the two most commonly used plastics are UHMW (Ultra-High Molecular Weight Polyethylene) and HDPE (High-Density Polyethylene). Both these materials are excellent choices for sled runners due to their low friction properties and durability.
UHMW is known for its exceptional wear resistance and self-lubricating properties.
It offers superior performance when it comes to sliding smoothly along the table saw’s surface, ensuring precise and effortless cuts.
HDPE, on the other hand, is also a great option that provides good durability and low friction.
Both materials have high resistance to chemicals and can withstand the pressures exerted by the sled during cutting operations.
Ultimately, the choice between UHMW and HDPE for your table saw sled runners will depend on your specific needs and preferences. Consider factors such as the type of projects you work on, the frequency of use, and your budget.
Overall, UHMW and HDPE are both excellent options for table saw sled runners, offering high performance, durability, and smooth sliding for precise cuts.
Whichever material you choose, make sure to properly install and align the runners for optimum performance and safety.

Phenolic runners provide smooth gliding action and are less likely to be affected by moisture or humidity.
When choosing the material for your table saw sled runners, consider factors such as your budget, the type of woodworking projects you typically work on, and the specific demands of your table saw. Each material has its own advantages and disadvantages, so it is important to choose the one that best fits your needs.
Polyethylene plastic
Polyethylene plastic is a popular choice for table saw sled runners due to its durability and low friction properties. It is a type of thermoplastic polymer that is derived from ethylene monomer units. Polyethylene can be found in various forms, including high-density polyethylene (HDPE) and low-density polyethylene (LDPE).
Benefits of polyethylene plastic:
1. Durability: Polyethylene is known for its high resistance to wear and tear, making it suitable for long-lasting use in table saw sled runners. It can withstand the pressure and friction that occurs during repeated use.
2. Low friction: Polyethylene has a low coefficient of friction, which means it allows the sled to glide smoothly over the table saw surface. This reduces the amount of effort required to push the sled and provides more accurate cuts.
Choosing the right polyethylene:
When selecting polyethylene plastic for table saw sled runners, it is important to consider the type and thickness of the plastic. HDPE is commonly preferred due to its higher density and better resistance to chemicals and moisture. Thinner sheets of polyethylene may be suitable for smaller sleds, while thicker sheets may be necessary for larger sleds.
It is also essential to ensure that the polyethylene is cut accurately to fit the dimensions of the table saw sled. Precise measurements and cuts will help to achieve a proper fit and avoid any movement or instability during use.
In conclusion, polyethylene plastic is an excellent choice for table saw sled runners due to its durability and low friction properties. By selecting the right type and thickness of polyethylene and ensuring precise measurements and cuts, users can enjoy smooth and accurate cuts with their table saw sleds.
UHMW plastic
UHMW (Ultra-High-Molecular-Weight) plastic is a popular choice for table saw sled runners due to its excellent properties.
UHMW plastic has a low coefficient of friction, which means it provides a smooth sliding surface for the sled. This helps to reduce friction and ensure smooth and accurate cuts. The low friction also reduces the likelihood of kickback and improves overall safety.
Another advantage of UHMW plastic is its high wear resistance. It can withstand constant use and contact with the table saw surface without wearing down quickly. This makes UHMW plastic a durable and long-lasting option for sled runners.
UHMW plastic is also known for its high impact resistance. It can absorb shocks and vibrations without cracking or breaking. This is especially important when using a table saw, as it can help prevent damage to the sled and ensure stability during operation.
In addition, UHMW plastic is chemically resistant and can withstand exposure to various chemicals commonly used in woodworking. It is also resistant to moisture and does not swell or warp when exposed to water or humidity.
When using UHMW plastic for table saw sled runners, it is important to choose the appropriate thickness and width for your specific needs. Thicker and wider UHMW plastic can provide added stability and support, while thinner runners can offer more flexibility.
| Advantages of UHMW plastic for table saw sled runners: |
|---|
| Low coefficient of friction for smooth sliding |
| High wear resistance for durability |
| High impact resistance for stability |
| Chemical and moisture resistance for longevity |
High-density polyethylene (HDPE)
When choosing the right plastic material for table saw sled runners, high-density polyethylene (HDPE) is a popular and effective choice. HDPE is a strong, durable, and resistant material, making it ideal for sled runners that need to withstand the repeated sliding and impact on a table saw.
HDPE is known for its excellent abrasion resistance, allowing it to maintain its smooth surface even after extended use. This smoothness reduces friction between the sled and the table saw, resulting in less resistance and smoother cuts. Additionally, HDPE has a low coefficient of friction, meaning it slides easily across the table surface without sticking or snagging.
Another benefit of HDPE is its dimensional stability. It resists warping, swelling, and shrinking when exposed to temperature changes or moisture. This stability ensures that the sled runners maintain their precise fit and alignment, enabling accurate and consistent cuts.
HDPE is also a lightweight material, which makes the sled easy to handle and maneuver. Despite its light weight, HDPE is tough enough to withstand regular use without cracking or breaking.
Advantages of High-density polyethylene (HDPE) for table saw sled runners:
- Durability: HDPE is a strong and resistant material that can withstand the sliding and impact on a table saw.
- Abrasion resistance: HDPE maintains a smooth surface even after extended use, reducing friction and improving cut quality.
- Low coefficient of friction: HDPE slides easily across the table surface without sticking or snagging.
- Dimensional stability: HDPE resists warping, swelling, and shrinking, ensuring precise fit and alignment.
- Lightweight: HDPE is lightweight, making the sled easy to handle and maneuver while still maintaining toughness.
In conclusion, high-density polyethylene (HDPE) is an excellent choice for table saw sled runners due to its durability, abrasion resistance, low coefficient of friction, dimensional stability, and lightweight characteristics. Consider using HDPE for your table saw sled runners to enhance your woodworking experience and achieve accurate and smooth cuts.
