With wood routers, working safely almost always equates to working more confidently. When you are not sure how to use a power tool, especially something as intimidating as a router, it can lead to bad cuts, frustration in woodworking and possible injury. There are lots of great things that can be built, changed, tweaked and enhanced with a router, so knowing your router basics can positively change how you do woodworking.
Always test your cuts on a similar scrap of wood to confirm proper cutting depth. If the wood burns, sneak up on the final cut depth by making three consecutively deeper cuts (see photos, below). Removing a little wood at a time will prevent burns.
