Your thoughts on a couple of Design Ideas

[Sterob]

I am in the throws of massaging my design and have an idea that I have not seem implimented yet......( It probably HAS but I have not seen it. )

I want to maximise my bed area as I have the Ali Plate already cut and machined ( 725 x 480mm ), so I am thinking I could extend the sides of the Frame so the Gantry Carriages can move past teh end of the bed. This will allow the Spindle to machine right to the edges.
A good idea, or very silly?

This would allow a wider spacing (200mm or so )of the Y Carriages to obtain more rigidity.
Worth doing as well?

It would mean longer Linear Rails, but not Ball screws as the mounting block would be central. I could just use the longer ball screws for build simplicity.

I also am thinking about trying to 'triangulate' the Base Frame. It won't be possible to do a full triangulation, as the spaces are not square ( rectangular ) but 2 partial braces may work ok?

Your thoughts?
