I have to take my hat off to you lot, I'm amazed you can cut it at all with a router, I have trouble milling the stuff.

Not the same trouble mind you, My problem is holding it down because the tool tries to lift it and it doesn't resist much.

I think it is practically pure aluminium, not enough magnesium, you could probably stretch it into a Coke can but that means the tool can push it out the way rather than cut it. Any interruption of the suds and the tool clags up, stops cutting and starts extruding.
