The RIDGID R4514 is a portable job site table saw designed for a variety of cutting tasks. To use a stacked dado blade set on this table saw, you need to consider a few factors: Arbor Size: The table saw's arbor (the shaft that holds the saw blade) must be compatible with the stacked dado blade set you plan to use. Stacked dado sets typically have a larger diameter than regular saw blades. Make sure the table saw's arbor can accommodate the dado blade set you intend to use. Dado Throat Plate: You may need to purchase or use a dado throat plate that is specifically designed for the RIDGID R4514. A dado throat plate allows for the wider dado blade to pass through without obstruction. Motor Power: The table saw's motor power should be adequate to handle the increased load when using a dado blade set. Check the saw's manual or specifications to ensure it can handle dado cutting. Safety: Always follow the manufacturer's instructions and safety guidelines when using dado blades or any other accessories with your table saw. Dado blades can be more dangerous than regular blades due to their wider cutting width, so it's crucial to use them correctly and take appropriate safety precautions. Stability: Ensure that the table saw and stand are stable and secure when using a dado blade set. Dado cuts can put additional stress on the saw and workpiece. Before attempting to use a stacked dado blade set with the RIDGID R4514 or any other table saw, consult the saw's manual and, if necessary, contact the manufacturer or a qualified professional for guidance on compatibility and safe operation.
