What about a router attachment and various bits for the Dremel? MUCH better and easier to use for small detailed work (I used a router attachment and a tiny router bit to shape fret marker inlay holes in new fretboards I'd make for guitars and banjos back in my pre-airsoft days, to install custom made abalone stars and moons and whatever else I'd make. Always worked perfectly!)
Aluminum is easy to work with, but a lot of bit types may/will get plugged with metal (case in point, using a metal grinder to shape aluminum or copper, plugs the wheel up repeatedly.)
