Help! Polished through the brushed aluminium panel

16 replies

I was restoring a beomaster 2200 and it had so close to finished. So much was broken inside and I spent a week getting it all working properly, and only had minor work to do on the exterior. I had all the panels polished, almost perfect bar a deeper scratch on one panel. I started trying to buff it out, it wouldn't budge, I moved down a grade, repeated as nothing was changing, then suddenly - went right through the surface. It's a mirror finish blemish and looks ugly as hell.

Does anyone know if it's possible to get this back in line with the rest of it?

Post some photos.

Think you got through the anodising layer which is approx 10-20 micron thick.

Can be stripped off and reanodised

Easier to judge with some photos.

Sorry meant to attach there.

Would I just have to sand off the whole panel? Seems like it will be very difficult to get the grain to match the panel beside it.

No idea how to reanodise really, is it very important?

The answer to that question will be no, unless you are working at B&O.
Only B&O can put that type of eloxation onto aluminium.

You can replace the affected panels, though.
Is it both the large panel and the hinged lid?

Just the hinged lid for the programming section.

Might be best to just sand through and get some kind of uniform grain?

Better send me down the dungeons and have a look for a good used original panel.

You've got through the anodising layer and down to the raw aluminium.

Anodising is not a DIY job, but there are many companies offering that process.

It is not a B&O invented thing.... But they master it good.

However, the customers of these companies are mostly businesses and not private people.

However, even if they etch all anodising off and re-anodise the part, you will still see the old scratch and some of the texture in the surface will be missing where you did the polishing.

But the color will be the same again.

You will need to do this process for both panels, otherwise there will be color difference

Now you also have the possibility to make it unique if you go for e.g bronze anodising or any other color.

In the end the cheapest solution will be to find replacements.

In which country are you living?

 

You cannot just sand it all down. The result will be terrible. The aluminium surface will be unsealed and fingerprints will be all over the place. The anodising layer is hardening the surface and is sealed. Been there done that.

Thanks Martin! Any idea what the price would be? 

Oh no, that's what I was afraid of! Can't believe how close to perfect it was only to be completely ruined at the last hurdle. I'm in Northern Ireand
