Here are some essential tips for getting top-notch results. To prevent catches, make sure your fence face is flat and smooth.
A featherboard is a good way to improve control and get consistent cuts. The trouble is knowing where to set them up. Here are two quick tips. A featherboard attached to the fence prevents a wide board from riding over the bit.
