Lower Cowling Hinges

Today I riveted the lower cowl hinges.  I did some additional sanding to make sure the fit was proper.  I continued to use the squeezer to install the flush rivets to the lower cowl.  After all of the hinges were riveted in place I installed the lower cowl to the fuselage with the hinge pins.
I drilled the 8-#19 holes in the front of the cowling.  There are 3-holes drilled at the front on each side of the propeller opening.  There is 1-hole on each side for the attachment of the side hinge pin knuckle.  I used the microstop to countersink the holes and then riveted nutplates in place.
