Brad assisted me with drilling the top cowl hinge.
Install the top cowl. Mark the location of the knuckle. Remove the top cowl and create a notch for the knuckle. Reinstall the top cowl.
Using the shadow of the top half of the COW-10-03 Side Hinges visible trough the top cowl, layout a rivel pattem with one inch spacing. Leave 5/16 edge distance at the forward and aft ends of the side hinges.
Reach in through the air inlet and hold the forward portion of the side hinge tightly against the top cowl. Drill #40, starting at the front, the top cowl to the side hinges. Cleco each hole after it is drilled.
