Right I decided that I had to have a go at aluminium, just couldnt resist the urge!.
I made up a dxf through autocad for a box drilling jig for some welding test boxes that I make.
The material is 10mm thick alu and I used a 3/16 end mill, didnt have a 5mm one, I need to build up my cutting tool supplies.

Admittedly I did forget about the top face of the jig, at the moment I am still too used to programming for profile cutting. This would have looked better with a bit of a clean up.

The box lid to be drilled and it fits snugly inside the jig.
All in all I am quite pleased with my first alu job. For using an old cutter and for a first attempt I'm a happy chappy.
I have also done a bit of video for parts of the cut and hopefully after my little gilrs 5th birthday party this afternoon I might get it loaded up to youtube.
