SKINNY FINGERS BY JOE NORRIS

WHEN WORKING ON AIRCRAFT, someday you’ll need to put a washer or nut into a confined area. You can see where it needs to go, but you just can’t get your fingers in there. EAA member Al Burgener came up with a great solution to this problem. He calls his tool “Skinny Fingers.” Al made his Skinny Fingers out of music wire that he hammered flat on two sides. That keeps the fingers from rotating when held within the handle. You can bend the tips of the wire into whatever shape works best for what you want to hold. The most common shape is to make each one into a half-circle as shown in the illustration. The inside diameter of the tips of the fingers need to be squared off vertical to the flat top and bottom surfaces so that the fingers will get a good hold on the item you’re trying to place in the confined area. The handle is made from a piece of 1/4-inch outside diameter aluminum tubing about 3 inches long. To make your Skinny Fingers, insert the two fingers that you’ve prepared as outlined above into the piece of aluminum tubing, then hammer the tube down onto the flat surfaces of the wire. The fingers extend out of the handle about 4 inches or so. This size works great on nut sizes from about No. 8 to 5/16. A larger set of Skinny Fingers will be required if you want to hold onto anything bigger. That’s all there is to it! A little time and some inexpensive components will result in your own set of Skinny Fingers.
