Any more than that and I think it would significantly shorten the life span of the machine or you'd start breaking cutters.

You can get by cutting aluminium on these CNC routers and get some nice results with the right cutters being careful to dial in your feeds and speeds but I wouldn't fancy doing it often on larger jobs. Its fine for things like amplifier plates and such though.
Thanks for the info. That's faster/deeper than I was expecting TBH. What's the cutter you were using? I suspect my carbide spiral cutters would be capable of alum, but they're 2 fluted.

I've got a couple of (non-loudspeaker) related ideas I'm considering, and I'd love to try them in aluminium. They're small, so I would be happy trying just 1mm DOC, but I'm worried my router may not be too great at 9000rpm.

The irony is that they appear to be constructed from carbon fibre, but weigh 900lbs each, which is kinda not the point with cf if you think about it .

before someone would think this, i'm NOT trying to accuse anyone from anything. I thought and still think that designwise the Apollo and siblings are damn fine pieces of work. And for the record: I like Shin's much better.

Its getting to my favourite part of any build. Spraying! I've been agonising over colour choices for more hours than I dare admit. Here's the one's that I've settled on.

First is a metallic black, which is a little more interesting than the usual straight gloss black.

Pearl white. For such a simple colour I've had a hard time tracking down the one I wanted. Most of the pearl whites are slightly creamy and I was looking for a clean looking white.

Not so subtle here is a deep red candy tint over a shimmering silver. Looks stunning in the flesh.

And finally a blue pearl.
