Started the welding project for the topper tonight and finished the frame. I used 1/2" 16 ga square tube and bent it by hand using a jig I made from a 2x8 and the groves in the cast iron plate on my drill press. Took me a long time to bend the stuff and pound the bajesus out of it to get it to form the radius of the wood. Not quite perfect but I got all five within an 1/8" of right on. I'm planning on hinging it all along the front and using gas struts for the hold open. Haven't decided what to cover it with yey. Maybe 18ga sheet steel, have a canvas made or a couple sheets of marine Luan with West epoxy. Have to give it some thought. I like the Luan idea but I don't want to look like a Hippy.
Started using CO2 and Argon in the welder also and I am kicking myself for not having done it sooner. I couldn't beleive the difference in the ease of drawing a good bead and the neatness of the welds. Huge difference. Never look back. Give me your thoughts

.I think the 20ga. CR was the right call. A good compromise for weight and streingth and still easy to work with. The color is off because of the reflection in the metal from the wood in the ceiling. The edges in the photo look really sloppy but that is just the grinder grain. I havent sanded it yet. I wraped the sides around the L channel and that will be the most important lesson for this project. Take the sheet stock to a bender and have good bends put in. That is the weak spot with this project
