Metal pressing
 

Having done some investigating courtesy of our friends at Google, it
seems that pressing metal sheet into useful shapes always involves
costly die-making and huge presses.

Is there any way to do it at home, with minimal equipment? I could
fabricate form/die of wood and use a bottle jack for pressure, no? The
pieces are not too big and the metal not too thick, under 1/8th inch.

Any suggestions welcome. The project is a fully enclosed chaincase for
a motorcycle.

Greetings Ted,
Look he www.bonnydoonengineering.com/
This web site explains how their presses work pressing shapes using
polyurethane. You can certainly use a hard wood like maple and a
bottle jack to press certain shapes. But it all depends on the metal,
the metal thickness, depth of the shape, etc. The above web site
should give you some ideas about what is possible. Also, the parts
might be good candidates for hammer forming. With hammer forming the
part is basically hammered to fit a form made from hard wood,
aluminum, or steel. Google for hammer forming.

Several of them, as I understand. I know a guy who used to form
stainless steel sheet of 14-16 ga in epoxy dies with a simple press.
There are other ways as well. I gather there's an entire industry
built around non-metallic metal-forming dies.

Good luck and let us know how it works.

Hi Ted,
Does it have to be pressed? A lot of shapes can be made by
hammerforming.

There's also explosive forming if you like making loud noises. Some
very heavy plate is economically formed that way. M-80's for light
work?

Thanks for your helpful responses. I'm intrigued by the hammerforming,
although it sounds kinda noisy for close neighbors.
