After gettng the attach angle and reinforcement plates ready, I cleared some space on the bench to set up the C-frame dimpler, and started dimpling the skin. Our oldest son came over with one of his daughters (the other is back at college) for his birthday dinner. After I got him to make a pic of his old man hammering dimples, we quit for dinner. Later I came back down and finished dimpling the skin. Next step will be to clean the parts good and mix up some of that gooey tank sealant and start the final assembly. About time, only about 3 years behind schedule.
