Re: Spec me a grinder/belt for finishing aluminium.
Given they are fairly small parts with tight nooks and crannies I'm not convinced you'll be happy with anything other than sand blasting.
You could try tumbling in a finer abrasive material like aluminium oxide grit (Like often used for blasting), that's more likely to get into the internal corners etc than the large tumbling media. You might need to experiment a bit.
Re: Spec me a grinder/belt for finishing aluminium.
Hmmm
Well I ordered the tumbler so will try it I guess.
Just need the media.
[edit]
I am not looking to finish the inside of the case, only the rounded bit a the front.
It is quite stepped so probably wont do much.
Re: Spec me a grinder/belt for finishing aluminium.
Dam this thing is gigantic.
And for £150 shipped that is quite impressive. I just hope it lasts long enough though.
Been talking with Moleroda Finishing and they are suggesting 10-20mm media.
10mm being higher chance of getting into the button holes I have so went for that.
Should arrive tomorrow and will get to tumble all day :)
Thanks for all the help guys.
Hopefully will come back with good results.

I assume that's an Anodised part going in the colour pot, is the noise your giant tumbler running in the background? :D
The part looks good BTW,

Posted the wrong video to the wrong thread.
Edited the post with the actual one.
And thanks!
PS, the noise is a server fan extracting fumes from the shed.
Re: Spec me a grinder/belt for finishing aluminium.
Crikey, that tumbler is a bit of a beast!
Looks like you're nearly there with everything, do we get to see the finished product when it's done?

It is really good and bigger than I expected. Only £150 too. Originally I discounted tumbling as I thought it was at least a couple grand for one that could take my parts.
The media is a bit expensive. This 10mm stuff is £66 with postage.
20mm is a lot cheaper, over half the cost. But I needed a bit more fine media to get into the smaller bits of my part.
Yea ill post photos somewhere.

Get some water and detergent in that tumbler and get the lid on!
The emphasis is on some - you want just enough water to keep things wet and clean, as too much dampens everything.
And it's noticeably quieter with the lid on.

Regular dish soap works fine right?
And I normally tumble with the lid on. Only had it off for the video.
