I took some time to inspect the rivets I set yesterday in the HS and VS. Most of the rivets were set nicley. 3 were not so I drilled them out and set new ones. This actually took about 3 attempts of setting and drilling out until I was happy with the results.
I found some spots were the squeezer set dies had gouged the material around the shop heads. This occurred on some of the rivets on the lower rudder hinge. I sanded the areas, deburred and refinished the metal. I spot primed the affected areas with some self-etching spray can primer.
you can see two of the cracked rivet shop heads in image 1 and 2. image 3 is representative of the repairs.
