Brief Description: Preparing the Right Wing Spar Caps
Image 1 shows how the countersink tool is located and then secured in place. The two wood scraps ensure that the clamps do not damage the aluminum flanges on the Spar. Image 2 shows the flange from above, ready to be countersunk. If you look closely you can see that there is a drop of liquid Boelube around the hole. Image 3 is of me countersinking the hole.
