How is it accomplished?
Hey guys, I was wondering how these type of metal finishings are accomplished does anybody know? Is it a special type of polishing machine? How is it done? I know you can buy decorative metal finish sheets but I want to know more about the process to make them. How would I go about trying to replicate something like that? Any info is welcome Thanks
PS.: I hove I've picked the right place to put this post if not, please feel free to move it to the right place. In the search for answers I came across this info: http://www.norcorp.com/design-alumin...pe-on-Aluminum 406.jpg 1810-Aluminum-Spiral.jpg che120510_img01.jpg

Hi Steve, this process is called engine turning. It can be done very simply with some basic tools. Google search the term "engine turning" and you may find sources for materials allready done and the supplies to do it yourself.

One of the guys at the recent Redneck Roundup (iirc- I know it was at Will's shop) talked to me about engine turning. Hopefully he'll post on this thread about some specifics.
In a nutshell, he said Establishing your pattern and layout is obviously important. But he talked at length about the ways different metals and abrasives behave. He described some metals as gummy, which load up the abrasive head and change the pattern of abrasive lines as you progress across the piece. Similar things happen when the abrasive deteriorates. Seeing a piece with the same swirl pattern across the entire piece is significant as keeping the layout accurate.

Some of us have done a fair bit of that "damascening" or "engine turning." Needed: Drill press or mill. abrasive powder or slurry - valve lapping compound, BonAmi, etc light machine oil round stick button made of leather, felt, foam ... (kratex not so hot, imo) Layout can be by eye: You can use your thumb and some 320 paper on some aluminum sheet, and twist your path across it ... Dates back to 1920's, it seems. Good for camouflage on poor surfaces. Or to fancy stuff up.

I can't thank you guys enough. I already searched the term on google and youtube and they have tons of info and videos on the subject and well as materials and techniques. That has opened up tons of possibilities for my future projects. Again I can't thank you enough guys.

I've done it small scale using these http://www.abrasivesales.com/quickor...s&req=cartroll
Kent when you say, "Good for camouflage on poor surfaces" does that mean difficult to camouflage surfaces or to hide poor work/degraded surfaces?

So, with a zillion spotwelds how is it going to look ...? - like the 8th Dwarf, who hangs out in the metal shops - "Lumpy." So, they swizzle-finished the whole hull - which helped camouflage lot, except when the light is just right, and then - dang, is that Lumpy ....? Another "camouflage" is using the DA, occipital sander, to go over finished parts. That random sander pattern is known in aircraft metal shops as "camouflage." hope this helps ...

damascened copper
One of my "artsy metal" pieces - when I run out of real parts to make ...
P1120538.jpg Laid out by eye and done by eye. Drill press. ex. fine lapping compound mixed with coarse rubbing compound 3in1 oil for slurry. Leather disc, slow speed, unfinished side of leather against work Wood dowel. (I am not a real artist. I made this for a real artist for his birthday.)

Engine turning
I use maroon scotchbrite discs or the leather pad with abrasive slurry. Don't be too precise with layout. When I used a CNC mill to do this it looked fake, like a sticker. I use a straightedge for the long run alignment and eye-ball the spacing. Center of one to the outside edge of the next.
I hated the fingerprints on my stainless kitchen cook top, so I engine turned that. I get lots of "Where do you by that?" comments. Another option is grinder art. grinder art.jpg
