DIY Build of Aluminium CNC Wood Router without Workshop & Tools

[WandrinAndy]

I'm busy with my design and have a query that references aspects of some incomplete bits within the circle in the attached pic.

The back part of the Y-beam and the top part of the X-carriage is going to be formed out of 152x51x9.5mm aluminium angle, which is coloured yellow.

I had decided to put the ballscrew-nut housing midway between the X-bearings as depicted by the grey block, but am now wondering whether it might not be better to maybe beef up the end of the Y-beam, attaching it securely to the vertical angle on the X-carriage, and simply make that into a ballscrew-nut housing, which would result in more "direct" drive to the Y-beam? The fact that this is towards the end of the X-carriage may not be ideal, but would it be acceptable or likely to cause problems?

Cheers,

EDIT: Have now cancelled that idea and am going back to Keeping it Simple!
