Place the fracture line over the edge of a table and bend the overhang slightly downwards. Assuming you can reach the back of the dent hammer directly on the crease while supporting the outside area with a dolly.
Work from the ends inward until the crease is broken.
How to get a crease out of sheet metal. Creases are extremely hard to repair. Once a piece of sheet metal is creased its well neigh impossible to take the crease completely back out of it. How to bend sheet metal without a brake how to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.
Useing the same methods to straighter a crease that you would use to straighten a simple dent may cause you some major headaches. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. Stretch type dents usually require heat in the form of a torch or friction disc to correct.
On a molecular level the increased heat causes the molecules of the sheet metal to become excited. One involves using a blow dryer or a paint stripper which emits heat to warm the metal of the dent. Some sheets worse than others.
It s been a whyle since i ve beatin on a 62 chevy but i remember those quarter panels being pretty flat. They vibrate at a slightly greater rate making the sheet metal more pliable. After this you would then have to do some welding to restrengthen the metal.
I keep getting deep creases along the top edge of my top sheets. A simple small dent on a flat or gently curved panel is the easiest to remove and as long as the backside of the panel can be accessed the dent can be erased using a hammer and dolly hammering. You would have to heat the crease till its glowing red then hammer it flat.
Sheet metal isn t all that different from a car s bodywork so most methods which will remove dents from a car work for sheet metal. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. The only one that doesn t do it is a no iron set from le.
The biggest problem is the damage done to the metal. You can iron them but they are always still visible and when using them on the bed the creases become more pronounced. After washing the crease is deep again.
It has become weak at the point of the crease. Once the tension is relieved from the crease the rest of the dent should easily hammer dolly out. Yup easier said than done.
Apply an equal amount of force used to create the crease in the opposite direction of the crease. This weakens the aluminium and creates a fracture line.
