Did some hammering with different ball peen hammers on a piece of 2 mm thick alu sheet. Started with a small hammer but I had the best result with firm hits with a heavy hammer. Also noticed the difference between a polished hammer head an a rusty one. As expected the sheet got curved by the hammering and I flattened if with a wood/leather slapper on an anvil. Arno

I would say that the dash is a hammered aluminum plate instead of sheet. 3/8" or even 1/2" thick, with just the surface hammered. It is the dash and not just a thin cover. Back side smooth.

Hammering thicker plate tries to curl the sheet a little but it is curling towards steel table it is being hammered aginst so the hammer hits flatten it out as you go.

Could have been done by hand or with a power hammer. Don't think it's embossed for the pattern isn't random enough at edges of dash. the hammer marks tend to row along the top and bottom of dash.

In terms of backing, an alternative to using pitch for something like this might be to clamp the aluminum sheet to a sheet of plywood. The plywood will keep the overall aluminum sheet flat, while the tool impacts will travel through the aluminum and crush the plywood underneath.

I believe that I saw Gene Olson do this a few years ago.
Peter,
I was working on a much larger scale.
the bulges in these trees,


or the scales on the dragon



both of those were made by stretching out the middle of the dent and then working it out until it collided with the reverse curve of an adjacent dent.
I think jesse's and richards comments are pretty close to the mark. Pitch or lead as a backing flows much like an annealed version of the metal itself.
To do it in sheet, and get all those crisp edges, you could either cover the back in pitch or lead and then wail away with the hammer.

I will note that the craftsman that did that dash had either VERY good hammer control, or he was using some sort of driven repousse tool, a domed die, placed where he wanted it and then hit with a hammer.

Default finish

I was gonna say that today as I was looking through one of the racks of material at work I found a couple pieces of material that looked to be the same. it was comercially bought in the past and has a thickness of around .020

My dad found a supplier in NY, I think, that carries embossed sheet in a variety of textures, including the faux hammered finish that dash is done in. I can give him a call tomorrow and pass the supplier along if you're interested.

oddly enough, he was using that hammered alu for a dash, too.
