Can't answer your question sorry, but maybe you can answer one for me, what is that a picture of? NICE.

Thanks

That would be the TacT Millenium All digital amplifier - or as they say it, a DAC with enough current to drive any speaker. Get yours today for USD 10K.

That looks like clear anodizing. You can send your pieces out to a plating shop and they can do this.

I would agree that it's clear, but how do you get that nice, uniform, whitish oxide on it?

A friend of mine sanded paint off of the aluminum boom for his sailboat and sent it to be clear anodized. It was clear alright; it looked like he just sanded it. You couldn't tell it was anodized. But most clear anodized extrusions like that are whitish, so ... I repeat myself.

Could there be some powder coating in there somewhere?

could aluminum be sandblasted?

rcavictim · 28th July 2004, 04:56 AM

Sure aluminum can be sandblasted. The surface will then look like the surface of sandpaper. There are many different componds that can be air blasted at the surface for different visual, effects including glass beads, lead shot, and crushed nutshells.

I believe the anodizing process involves a chemical etch which gives the fine satin coat surface structure. I would not sand the aluminum or blast it before having it anodized as the anodyzing is not a void filler.

For DIY I suppose one could experiment with a small sandblaster and crushed nutshells or something and then clear coat afterwards with spray lacquer.

Using a cloth pad and Colgate toothpaste as a polishing compound on an orbital sander might make an interesting finish. Add water as necessary.

Further to my previous post since my edit time has expired....

I have been thinking casually about making a device that will attach to the side of the nozzle of my high pressure washer that sprays clean water at about 2250 PSI and 2 GPM. Anything hurled into the path of the water jet after it leaves the nozzle would be accelerated instantly by the high pressure water stream. This could be a way of wet sandblasting for example.
