I have had luck with a small aminate trimmer it cuts AL ok but you need to make sure it is clamped well and your spped and feed are not too high. The Dewalt laminare trimmer has a hole on one side that holds the adjustable foot. This makes for a nice mounting location for the z axis. A clamp holds the upper potion tight against the z.
Also get a speed controler to allow to vary the speed on the trimmer, or buy one with it built in. You will want to slow it down as it is really too fast for most materials without a really high feed rate. The speed and a slow feed rate builds a lot of heat in the tool as there is not enough chip load to help pull the heat away.
