Making thin cuts on your table saw requires a zero clearance insert so that the stock doesn't get pulled into the table saw after cutting.
Most table saws have an insert that's good for a most applications: it can accommodate the blade at full height, at any angle, and has space around the blade that allows sawdust to be pulled down from either side of the blade. A zero clearance insert has no clearance around the blade, and should only be used when the blade is perpendicular to the table. Making your own zero clearance insert is easy, and we can even use the table saw to make it! Having one on hand is great for the few times you need the right tool for the job. To make this zero clearance insert I used
Because there is zero clearance between the blade and the insert there is no space for sawdust to be pulled away from your cut, however this is an easy compromise since without a zero clearance insert you would not be able to make thin cuts.
Ready? Let's make!
Remove your table saw insert and take the overall measurements: length, height, and depth.
To get accurate readings I used digital calipers. Make sure your saw insert housing is clear of sawdust so you can get the best readings. Most saws have height adjustment screws so you can level out the insert after if your readings are a little off, but it's better to get accurate measurements before starting.
