Brief Description: Closing the trim/elvator tabs with blind rivets.
Once the trim tab has been tweaked and clamped to strraighten out any warps (mine was perfect!), the tabs are drilled or match drilled for the blind rivets to hold them together. Tight fit for some deburring on the back side, but I did the best I could with my figners back there. Riveted them together and they came out even and straight despite some slight problems bending them earlier.
