Having a properly aligned table saw fence is essential for accurate and safe woodworking. Over time, the fence on a table saw may start to go out of alignment, causing inaccurate cuts and potentially dangerous situations. One common method of fixing this issue is by shimming the table saw fence.
To shim a table saw fence, you will need a few basic tools, such as a tape measure, a straight edge, and some thin pieces of material, like paper or plastic. First, start by measuring the misalignment of the fence. Use a straight edge to determine if the fence is parallel to the saw blade or not. If it’s not parallel, measure the gap between the fence and the blade at multiple locations.
Once you have determined the amount of misalignment, cut thin strips of paper or plastic that are slightly wider than the gap. These strips will act as shims. Place the shims in the gap between the fence and the blade at the locations where the measurements were taken. Use a light hammer or mallet to gently tap the shims into place.
After inserting the shims, check the alignment of the fence again. Use the straight edge to ensure that the fence is now parallel to the saw blade. If needed, make any necessary adjustments by adding or removing shims. Once the fence is properly aligned, tighten the screws or bolts that hold the fence in place and recheck the alignment one final time before using the table saw.
Remember, a properly aligned table saw fence is crucial for safety and accuracy. Regularly check the alignment of your fence and make any necessary adjustments to ensure the best woodworking results.
