Hi All,

I have this crazy idea of CNC'ing an engraved design into some sheet aluminium for my workshop door (if anyone knows the Doors of Durin, then you know the design).

Question is I have seen V Bits for wood and they're carbide or at least carbide tipped, but will they cut in aluminium or am I resigned to ballnose?

Also does anyone know of anything cheaper than Vectric VCarve for bitmap CAMming?
