If you’re looking to make your table saw more accurate, there are a few techniques and modifications that can help. The most important thing is to ensure the blade is properly aligned with the miter slots in the tabletop. If these are off by even a fraction of an inch, it will affect the accuracy of your cuts. Additionally, making sure all components (fence, blade guard) are level and parallel to each other will also improve accuracy.
One way to check if your items are level is through use of a machinist's level or straight edge placed along various parts of the saw such as its rip fence guides or miter gauge slots. This will give you an indication if it needs adjustment in order for everything to be perfectly aligned which ultimately leads to improved accuracy when cutting materials on the table saw.
You should also replace worn out blades with newer ones specifically designed for precision work since they have finer teeth that allow for smoother cuts without much effort from yourself. Also making sure any moving parts like belt tensioners and pulleys have been lubricated regularly helps keep them running smoothly so they don't cause any inconsistencies during operations either!
Finally, zero clearance inserts should be used in place of standard throat plates as this provides better support for small material pieces which can often move around while being cut due to their light weight nature; resulting in inaccurate cuts which defeats the purpose entirely! Zero clearance inserts not only provide extra stability but also create less tear-out on wood surfaces compared regular throat plates too so overall they're worth investing time into setting up correctly before use!.
