If you do any work with drills and screws you know that it eventually happens, a stripped head. You know how it goes, driving the screw home and it binds up, slows down and then the bit slips and spins and chews up the head. So you go from a Philips cross to a rounded out hole. Usually it happens just before you get the screw seated. Its to close to the work to use vise grips on it and its not far enough into the wood to just leave it. So now what? Often trying to back it out just strips it the other way so now it doesn't go in or come out. Well there is an ideal Dremel fix for this.
Step 1: Enter the Dremel
Put the cutting wheel on your Dremel and use it to cut a slot into the messed up screw head.
Don't cut it to deep but deep enough so you can get a regular straight bladed screwdriver into it. It should be cut close to the middle but if its a little off don't worry about it. All you want to do is get this screw out, not make it look pretty. Avoid cutting into the wood if you can. And of course don't have anything flammable around when the sparks are flying.
