FWIW…..When working with woods such as hard as maple, chances are the wood is going to burn unless you slow the cutter way down. If you can vary the speed of your drill press, your chance of burning the wood are greatly lessened. If you can't vary the speed, MLCS (www.mlcswoodworking.com) makes a $30 gadget which allows you to vary the speed of a router. You can check with their tech support people to see what other applications it's good for. Pine, on the other hand, is much softer and shouldn't burn when you cut the plugs.
Unlike those woodworking shows on TV, I also don't have a bottomless budget. I wish the people who produce those shows would work with tools that are found in most home workshops.
