If you’re building a table saw sled, it’s crucial that it produces crosscuts close to 90 degrees. Last time, we talked about William Ng’s 5-cut method for truing up sleds, but there’s another method that requires almost no math: the 2-cut method.
Start by squaring up your fence with a carpenter square, adding a screw for your pivot as well as a temporary screw. Take a piece of sheet wood with one true edge, place it against the fence, and make a cut. Mark the top right corner of the left piece with a "1." Now, flip the second piece to the left side, make another cut, and mark the top right corner with a "2." Flip that piece over and butt it against the first piece. If the pieces are flush, you’re set. If not, use a feeler gauge to find the gap—it’ll represent twice the error.
If there’s a gap at the top, your fence is too high on the left. If there’s a gap at the bottom, it’s too low. Move piece "1" against the left side of the blade and mark the fence at its width. Adjust the fence up or down by half the thickness of your feeler gauge reading. Like William Ng’s method, use a corner of a piece of stock to make these adjustments.
