Cast aluminium gantry router

[jrcast]

Good idea about the kickstarter, maybe I should keep all my ideas secret in case anyone nicks them :)
Sod it, here's some pics.
Here's the start for the gantry pattern. It's 19mm thick and longer than I need as I'm thinking about doing a kit and the gantry can be cut to size. All needs to be sanded smooth and all the inside corners need to have wax fillets put in.
