Essential Craftsman - The Two-Bladed Monster Saw: 1940's Oliver Table Saw
The Oliver number 260 is a vintage saw from the 1960s, featuring two arbors with separate blades for cross-cutting and ripping. Each arbor is powered by a five-horsepower three-phase motor, allowing for precise and powerful cuts. The fine-tooth blade is ideal for cross-cutting, while the skip-tooth blade excels at ripping. The saw's engineering allows for smooth, accurate cuts with minimal tear-out, making it superior to modern saws in some aspects. However, the saw lacks a riving knife, which poses a risk of kickback, emphasizing the need for caution and additional safety measures. The presenter shares personal experiences and stresses the importance of safety, especially when using such powerful equipment, and highlights the saw's historical significance and craftsmanship.
Key Points:
- The Oliver 260 saw has two blades: one for cross-cutting and one for ripping, each with a dedicated motor.
- The saw's design allows for smooth, accurate cuts with minimal tear-out, outperforming some modern saws.
- Safety is a concern due to the lack of a riving knife, increasing the risk of kickback.
- The saw's historical craftsmanship is highlighted, showcasing its engineering excellence.
- The presenter emphasizes safety and restricts use to experienced individuals to prevent accidents.

2. ⚙️ Exploring the Saw's Capabilities
- The saw is capable of fine tooth cross-cutting, offering precise, smooth, and accurate square cuts on wide boards, which is essential for high-quality woodworking projects.
- Equipped with a 20 lb miter gauge, the saw enhances cut accuracy, crucial for precise long cuts, making it particularly useful before the era of sliding compound miter boxes.
- The saw can rip boards up to four and 1/8 inches wide, making it suitable for crafting large furniture pieces like dining room tables.
- For operation, the saw requires starting a three-phase power system using a rotary converter. This setup is necessary for users who do not have direct access to three-phase power.
- The rotary converter provides reliable three-phase power, which is essential for the saw's functionality, ensuring consistent and efficient operation.
3. 🪚 Comparing with Modern Tools
- The modern tool is compared to a small sawmill in terms of power, demonstrating the ability to rip through 4 inches of Douglas fir effortlessly, highlighting its strength in heavy-duty tasks.
- Adjusting the tool for cross-cutting requires 26 cranks, indicating a manual and time-consuming process that could be improved for efficiency.
- In cross-cutting performance, the tool surpasses the SawStop tool, except in scenarios involving very big rips or smooth cross cuts, suggesting a competitive edge in precision tasks.
