Place a small piece of duct tape over the head and force or tap the screwdriver bit into the recess. Many times with this trick, you can generate enough torque to remove the screw. Throw away the removed screw and replace it with a new screw! 3. Add a small amount of valve grinding compound on the screwdriver tip; sometimes that creates enough friction between the driver and the screw socket to remove the screw. Throw away the removed screw and replace it with a new screw! 4. Slot the head with a thin cutof wheel or even a hacksaw. Then use a straight-bladed screwdriver. Throw away the removed screw and replace it with a new screw! 5. Drill the recess with a left-hand drill a little smaller than the screw shank. If the left-hand drill doesn't back out the screw, use an easy-out in the drilled hole to remove it. Throw away the removed screw and replace it with a new screw! Finally, here's the story that generated this tip. A couple of years ago, a lady pilot came to the Emergency Aircraft Repair at EAA AirVenture Oshkosh. On her preflight, she discovered the spinner on her 172 was cracked, and she wanted to remove it on the ground instead of having it come off in the air. If you have ever had a spinner let loose, you understand her request. A quick look at the attachment screws revealed that not only were some of the recesses damaged, they were rusty and full of paint. The screws hadn't been removed in years. All the above procedures just made the recesses worse. So I reverted to an old blacksmith trick. I used a hammer and a sharp chisel, not to take off the head but to slowly rotate the head with gentle taps of the hammer on the chisel that is off to one side of the screw head and biting into the head. We threw away the screws! E A A E X P _ J u n e 1 4 . i n d d 3 3 EAAEXP_June14.indd 33 6 / 3 / 1 4 8 : 4 1 A M 6/3/14 8:41 AM
