Well, while trying to replace a few rivets on my keel guard on my boat I pulled a bonehead move and made a few holes too large 9/32" instead of 1/4". Im using 1/4" diameter closed end rivets as I don't have access to the inside of the hull without ripping the entire boat apart.
SO.... before we go any further I'll explain exactly where they are on the boat, they are all located on the very bottom on the keel guard and a couple where the keel guard starts at the towards the bow, so I will be going through 2 or 3 layers of aluminum depending on the location.
I cannot find 9/32" or 5/16" diameter closed end rivets because I assume they dont make them(Please correct me if I'm wrong).
I figure my options are as follows.
1. I use the 1/4" rivets with 3m 5200 and hope they hold,(they should snug down but they are slightly beyond the maximum sized hole allowed for 1/4" rivet, so Im a little worried.
2. I get some stainless steel screws with a coarse thread and simply screw them into the holes with 3m 5200( not sure how much larger diameter screw I should use)
3. Is option C...(your suggestions)
Im looking for the most structurally sound option without ripping my entire boat apart to gain access.
