Cutting Acrylic sheet

I've been asked how to cut acrylic with a hot wire cutter - I made my own and there are a few plans for how to do this on instructables etc. This was my take on the idea which I find works OK for me... - see the file attached

Aluminum Frame

I am trying to build an aluminum frame for my robot but I am having trouble finding good techniques to cut and bend it. Anyone know a good way to cut and bend aluminum for a frame? I have basic tools, but not anything fancy. The frame needs to be about 7.5 inches and relatively sturdy.
