If i could give one bit of advice to those forming aluminum it would be to limit extensive stretching in small areas.
Hand forming sheet aluminum.
Aluminum strains locally meaning that it has poor stretch distribution as well as poor elasticity.
Molecularly speaking shrinking compresses the space.
Stretch the metal around the radius bend and remove the buckles gradually by hammering on a wedge block.
Some of the more interesting combinations use a soft top die and a hard bottom one.
We perform brake roll bump hand forming hot joggle fabrication and machining to complete a quality product.
Hammer the flange down over the form striking the metal with glancing blows at an angle of approximately 45 and with a motion that tends to pull the part away from the radius of the form block.
With a combination of these manipulations you can create anything from flat sheet and you can do it by hand.
Hand operated bead rollers like this one form beads and ribs into sheet metal.
Some are quite malleable and others so hard and springy as to challenge attempts to work them.
