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

Yeah... that is really a pity.

There are three options.

1. keep them... live with it. It will remind you never to do similar things again Erm..

2. re-anodise... I am in DK so I don't know this company. But visit their webpage. They can strip them down and re-anodise. The stripping process will etch some of the texture away on the complete surface. So the texture/brush pattern will be reduced. But why not call them. Tell the story... and who knows... maybe they will do it really cheap because they understand the shitty situation. Maybe they can re-brush them as well. I would imagine they can. https://www.techmetals.co.uk

3. Buy replacements...

Good luck.

Those are good ideas! Thank you.

 

I'll try ringing a company that might do it and see what they say. Otherwise it's probably live with it unless I can get a very cheap replacement. I got this in a bulk buy with some other B&O products, and this was the only one that survived the shipping without some irreparable damage, so I was hoping I could fix it up cheaply so as not to make it a total loss </3

A very cheap replacement?
In other words not worth it for me to have a look in the dungeons then.

In Denmark you find them for 20 pounds... but that does not help you much in Northern Ireland... and shipping is pricey.

Keep in mind that the logo will go away if the panels are re-anodised. And the plastic parts must be removed first.

Have a look at this:

Have a nice evening.

Don't worry about it Martin, I'm sure they will find out the hard way!

Thanks for the help guys but I think I'm just going to live with it. I know they're not worth all that much as far as beomasters go, so in my case I don't think it's worth spending a lot more on it just to bring it back up to acceptable condition where it wouldn't be worth much more than the replacement parts themselves.
