Did you know Raymond DeWalt was credited with the invention of the radial arm saw in 1922 and later acquired the patent in 1925? 50 years after the radial arm saw was invented, the power miter saw was introduced in 1970s. The radial arm saw, nonetheless, was used as the primary tool to cut stock to length during those 50 years and is still in use today; it could also be configured to make cuts for half lap, dado, and rabbet joints with a dado blade. Finally, some radial saws were able to be turned parallel to the back fence to make rip cuts. As the years passed, improvements were made to the radial arm saw, which resulted in a versatile cutting machine that can tilt on all axis except vertical.
In this post, we’ll share a brief history of the radial arm saw, and the benefits of installing an electronic brake onto the machine.
The invention and history of the radial arm saw
The most successfully sold version of the radial arm is the Wonder Worker; DeWalt’s originally patented design. It was a circular saw driven by an electric motor held in a yoke that slid along a horizontal arm positioned above a horizontal table-surface.
Prior to the radial arm saw, tools like the table saw or the hand saw were used for cross cutting timber. The table saw cut through stock effectively, but it was awkward and dangerous to push wood through the blade. The introduction of the radial arm saw allowed for the stock to remain stationary on the horizontal surface, which increased safety and ease of use for operators, and the blade to be pulled through the wood during cross cutting.
In the 1970s the power miter saw was introduced to stock cutting. It allowed for easier cross cutting and miter cuts. The miter saw was not able to complete rip cuts like the radial arm saw. Although the miter slowly replaced the radial arm saw for a certain subset of cuts, the radial arm saw is more precise and offers a larger variety of cut options to the operator.
Fast forward to the radial arm saw now, and you’ll find it in a lot of shops being used for a variety of cuts. It is a common replacement to the table saw, and it’s used more out of the woodworker’s preference than superiority to any other tools.
The benefits of electronic brakes on your radial arm saw
At Ambi-Tech, we believe that DC braking systems are the best for most AC induction motor braking applications. The DC injection brake is quieter than your average friction brake. It allows operators the ability to stop machines quickly to avoid safety hazards and impending damage to the equipment and materials. Friction brakes wear out over time and require ongoing maintenance. Electronic motor brakes require little to no maintenance.. Finally, DC injection braking does not require a method of actuation like friction braking systems.
After 50 years of providing maximum motor stopping power for hundreds of applications including woodworking and metal cutting machinery. Ambi-Tech knows what it takes to brake machines effectively.
