Shaping aluminum sheet
I want to do some modeling with aluminum sheet. I haven't done much of this and there will be a lot of compound curves. I will probably buy some sheet material of about 14 or 16 gauges and do my best at stretching and shrinking it to suit. While thinking about this, my mind asks why I can't lay up sheets of foil into the shape that I want, and why can't I do this with superior structural properties. How best to bond thin aluminum sheets into a solid material. Should I use a spot-welding process? Should I use a pressure bonding or cold weld method? Should I use an adhesive? Would it be an advantage to use hard adhesives in some areas and maybe flexible glue like silicone cement in other areas?
I guess I need to do some experiments.
