Question:

anyone know how AIRSTREAM Campers make their rounded metal shell? I want to replicate it for my project :)?

i assume it's aluminum maybe? and they probably shape it somehownot sure how though?I know how to make flat curves with a saw into thick plywood every inch or so without cutting throughthat makes it bendbut their curves are 3dhow do they do that???

Answer:

NoYou should consider a reduction and lift.
If that's your real picture then no Besides, implants are lame and fakeI prefer all naturalWho cares how big they are?
Its called an English wheelSee site for infoThe machine is shaped like a large, closed letter CAt the ends of the C, there are two wheelsThe wheel on the top is called the rolling wheel, while the wheel on the bottom is called the anvil wheel(Some references refer to the wheels by their position: upper wheel and lower wheel.) The anvil wheel usually has a smaller radius than the rolling wheelAlthough larger machines exist, the rolling wheel is usually 8 cm (3 inches) wide or less, and usually 25 cm (9 inches) in diameter, or lessThe rolling (top) wheel is flat in cross section, while the anvil (bottom) wheel is domedThe operator of the machine passes the sheet metal between the anvil wheel and the rolling wheelThis process stretches the material and causes it to become thinnerAs the material stretches, it forms a convex surface over the anvil wheelThis surface is known as crownA high crown surface is very curved, a low crown surface is slightly curvedThe rigidity and strength in the surface of a workpiece is provided by the high crown areasThe radius of the surface, after working, depends on the degree that the metal in the middle of the work piece stretches relative to the edge of the piece.
