I enlarged the picture and it looks like a two sided emboss sheet that was rolled. One roll is male and the other is female.
If you are going to try to make a sheet like that manually it will take a male and female die and probably want to do it in an arbor press one shape at a time. When you press the center down it will raise the edges on the face side of the panel. Keeping the sheet flat is going to be tricky. I think a nibbler will be too fast to control the pattern in the picture.

you could use a Pmax upper tool relase mechanism for this. Not alot of power, but it would be a positive stop. My bet would be for an arbor press with a stop of some kind on it after die height has been adjusted..

I believe you're going to have a difficult time keeping the metal flat as it is dimpled. Because it's aluminum, you can probably turn it upside down after it's dimpled and beat it flat with a leather faced slapper but I definitely expect it to develop some shape during the process.

thanks all for your comments. I try to tests with the nibbler next week and if I have any results I'll show you. Arno

Arno, I am pretty sure that finish on the sheet is from an emboss line. The finish was called "Pebble" and what you are looking at on the dash is the back side of the sheet. The front of the sheet looked like a lot of pebbles that formed a slightly raised surface for the pebbles and a lined recess around the pebbles. Maybe someone still makes that style of embossed sheet. We sold the emboss line where I worked in the late 1980's but hadn't run that product since the late 1970's. There were all kinds of patterns that were made, wood grain, stucco, one side diamond, two side diamond, leather, and others. If you have an aluminum sheet supplier in your area they might be able to tell you if someone still makes it.
Good luck with making the panel. Looking forward to seeing what you come up with.

Maybe you could use a rubber mallet and some aluminum on a pebble-tech driveway type surface to make the impressions. Might need a sheet of plastic or something to minimize marring the surfaceof the alloy material.

The sell sheets of ali with this finnish at our local B&Q ( Big DIY store) I also bought it once from a shet supplier and he called it STUCCO ... might not be the correct spelling ...

Embossed
Frigo Design offers a pattern similar to the one being discussed http://www.frigodesign.com/php/shower/textures.php#
It might be that what was used on the dash is simply the reverse side of the hammered product. I think with a little work, and a ball peen hammer, you could do the same. The question is what to back it up with. Another idea would be to use an arbor press. I agree that the pullmax would be cycling too fast, unless you have a speed control on it. John |
