Method 1: Use an abrasive cutoff wheel to cut a slot in the rivet head just above the plate
surface. Use a hammer and 3/4" (or wider) chisel to knock the remaining rivet head off
the surface. Drive the rivet body out of the hole with a punch. Take care not to grind or
gouge the aluminum plates or elongate the rivet hole (see Figure 6 & 7).
Method 2: Use a grinder with a course sanding disk to remove almost all of the rivet
head. Then use a tapered punch to drive what's left of the rivet out of the hole. If the rivet

Take care not to grind into the aluminum plates (see Figure 8 & 9).
6. Locate and mark six rivets from center of the top plate that line up with the six bottom
rivets previously removed. Remove these six rivets using one of the two recommended
