I got the top and one side drilled, cemented, and riveted in place today. I started outside in the driveway, garage is kinda full, but with the sheet metal acting like a mirror, I was getting cooked by the sun. Spent a while rearranging the garage, so I could work inside. The first pic is the center of the top frame assembly showing how I cut it to allow another stud to cross-brace underneath. On the top and bottom pieces I'm gonna' do this in 3 places for stiffness. The sides and back only get one. I situated the sheet metal in place, clamped and measured and drilled the holes for the rivets. Then I applied the cement and re situated the sheets, using a pin punch to align and clean the holes. The furnace cement is pretty easy to apply. Keep a bucket of water and a rag as you go. When you have one side/rail done, squeeze some water on it to keep it wet until you place the sheet metal on. Once all the rivets are in-place...I'm beginning to hate rivets...lol...wipe the seams (in/out down) to remove the excess. I tried to get a close-up shot of the corner seams/edge. I'm supposed to get my elements from UPS this evening.
