Author: Question by Adam Cordell: How are car fenders made?
I’m wondering what the process is for mass producing car fenders (metal). I assume the plastic fenders are made from injection molding but the metal fenders are what fascinate me. Also does anyone know of a cheap method for reverse engineering a fender other then 3d scanning?

They are stamped out of sheet metal with pattern on dies, expensive piece or equipment. No to other question.
Metal bends when heated.
im guessing you want to replicate a fender off a car your fixing? to do that, the cheap way is to buy some sheet metal of the same thickness. I warn you that the following is time consuming if you want to get it right. the first way is to hammer and screw bits of hardwood together and chisl and grind the shape of the fender into it. Then all you have to do is place your sheet in the template and beat it into shape with various shaped hammers.
