[QUOTE="DaleH, post: 385995, member: 15636"] Well, before I can pour I need to completely REPLACE the transom rear skin. I've seen a lot of posts here of people adding wood, but I have yet to see or find where someone has replaced the OEM rear panel. This was my method to remove it and [b][color=#FF0000]DE-rivet the boat[/color][/b] ... 1) Quick wire brush so I can see each brazier rivet head easily, whilst sitting down on the work stool - at best, or whilst lying under the boat -at worst. 2) Place dot on center of each rivet head w/ black Sharpie marker. 3) Using a prick punch (60-degree included angle or less) pick up the dot and strike with ballpeen hammer. 4) Switch to pin punch (90-degree included angle) and widen/deepen the spot to drill. Many may not know, but I learned this at GE's apprentice machinist school, that by using the 2 punches in tandem, you get a more accurate dimple to start the drill and it's even possible to tweak the center punch off to one side or the other if you had goofed a tad on the prick punch. 5) Drill in ~1/16" w/ 3/32" cobalt drill. Do about 6 or rivets, maybe more. 6) Drill in w/ 3/32" cobalt drill, I found that 3 quick medium power hits kept the torque on the bit and ~70% of the brazier heads sheared right off at the top surface. I didn't need cobalt for aluminum, but they sure stay sharper! 7) Punch out or through and replace every 3-4" with a Cleco temporary fastener. Lookie there ... she looks like a porcupine! [/QUOTE]
