Does reccomended edge distance change on aluminum depending on the thickness?
I understand it is preferred to have 1/4 in edge distance on most everything, but I'm under the impression that the tear out strength, and the propensity to crack on a 0.016 piece and a 0.063 piece of Alclad would be drastically diffrent for that same 1/4 inch and the same 4- rivet.
The reason I ask - I buggered a 4- rivet hole a wee bit (ovaled it with the countersink drillbit). It's on a slightly large, and therefore expensive and difficult to ship, piece.
I have some 5- rivets - I am thinking of over drilling and then bucking the larger rivet in the exact same place. There would still be a 7/32 or so distance edge of drill hole to edge of piece. (do you measure from the the center of the drill hole or the edge?)
I dont think this would be a huge faux pas as there are 4 other 4- rivets in proximity holding the pieces together.
Any opinions welcome.
