Making fenders.
Sorry if this is the wrong forum, but I couldn't think of a more fitting one.
I have some aluminum scrap I'm hoping to make compound-curved fenders out of, complete with rolled edge, but I don't have a roller, english wheel, power hammer, or anything like that, let alone knowledge of how such things are actually done. Instead I have pieces of hardwood I've shaped with hopes I could hammer the aluminum into fenders around, but I'm completely failing as I suspected I would. Does anybody have experience making metal fenders, or even an understanding of some processes used by manufacturers?

Not a fender, but apply what he does to the aluminium.

Re: Making fenders.
Probably a dumb question, but what type of rod and flux is he using to gas weld aluminum? I doubt I'd trust that on a bike but that is cool.

Form & pound it with a soft hammer over and old car wheel.

This guy carries a lot of the necessary supplies for gas welding aluminum. He uses it to mostly build airplanes and automobiles,

Re: Making fenders.
No fender exists that will fit my 20x2.4 tire, so I had to figure out how make them myself. Here is the blog post I wrote about it recently:

They are hybrid aluminum/wood fenders. The post may be interesting to a DIY type who has access to a table saw and can do (or learn) some hard-soldering.

Re: Making fenders.
I've experimented with 3D printing fenders....YMMV.
