    Hello, I am hoping that with the input of the members of this forum that I will be able to develop a design of a smallish router that is functional and reasonably simple to construct.My original goal was for a working area of 1300mmx1300mm, but for this machine it has been scaled down to a working area slightly larger than A3.This will be a fixed gantry 3 axis cnc, made mainly of steel with the exceptions of the Y axis extrusion and table.I hope that we can not only use this thread to discuss the design but also the methods of construction as I wish to learn how you would approach some of the problems I stumble across.I want this to be able to machine aluminium and wood so it needs to be rigid. I have already made a start on the side plates which are 12mm steel and very heavy (maybe a bit over the top).Here are a couple of sketches to start with.
