Trevor,
I have to say you are doing a marvelous job on your build. I have to ask this question of you and any of the ones currently building a 40. Are you using only rivets/nutserts, or are you incorporating any panel adhesives along with the rivets?? I ask this because i recently ran across some new information(actually rather old info) about the adhesives. My painter is currently adding a few stop panels in my gas tank for a flapper valve to keep the fuel near the fuel pickup. He related the story to me about when he went to work for a Ford dealership and started using the adhesives back around 91. The dealership challenged him on their ability to hold the panels in place since they were going to warranty the work. He set up a demonstration with two panels joined in a lap weld setup. Did it as he would any other panel and allowed it to cure for 24 hours. They hooked it up to a frame straightening rig and tried to pull the panels apart. the metals sheared before the panels moved. The adhesive is rather expensive and the gun cost about $100. It is a two part mixture. This stuff is able to stand up to gasoline as well, though it not recommend. He repaired a tank puncture with it and two years later not a leak. Just curious. i understand the use of rivets as a quick way to attach the panels. However, I can't think of a reason to remove them other than in a damage situation. I know they use them in the airline business, but they are interested in mass production. One of the reasons I chose the DRB(GT40 Australia) was the welding of the panels to the frame, and the strengthening of the frame assembly. Your thoughts and any others welcome.
