Best way to remove creases on very thin aluminum?
Hey guys, thanks in advance for taking the time to read this.
Well for a project, a piece of thin aluminum (0.080 gauge, basically 1/16 of an inch thick) was in a metal shear to be cut down to size, however there was a small piece of metal underneath it to which I didn't know about. The piece of the metal bar was far enough in, that it was sheared also, but under all that pressure; now the imprint of the metal shows through the thin aluminum. So I'm basically hooped, as it has to be immaculate.
Buying a new piece isn't possible, its a very large sheet of alumimum.
Hammering it out will only do so much, its as if the alum. is stretched a little to wrap around that bar.
I was thinking of hammering it down as best I could and sanding the remaining imprint down using an aluminum grinding wheel, then later finishing up with a SOS pad, as they are great for lightly sanding this type of metal down, much like 2000grit sandpaper would be to anything else.
I just need other suggestions, or whatever advice you could give.
MUCH thanks for any help of suggestions
