Time to start countersinking the spar for the big #8 fuel tank screws

The instructions say to saw off the head of the one tank screws and use it as a pattern to know how deep to make the countersink for the #8 tank screws. I used one of my magnetic phillips bits to hold the sawed off screw head. UPDATE 12/1/2006: This is a total waste of a screw. I got a scrap piece of sheet aluminum that was the same thickness as the tank and put #8 dimple in it to use as a hole checker. When it came time to put the tank on, I had to ream these holes out more than there were, using the hole checker as a guide.
