I'm going to need some help.

[asbo]

I've decided to build a metal CNC machine to replace my MDF one.
I'm going to reuse the supported rail, ballscrews, stepper motors and drivers off it. This means a single ballscrew down the middle of the long axis(I'd call this the Y but I know some people call it the X).

This is what I've come up with.
The aluminium extrusion is a mix of 45x45, 45x60 and 45x90. The plate is 20mm. The rails are SBR20 and the ballscrews are RM1605.
The dimensions are 1180mm x 756mm
Is it any good?


Whilst I have access to all sorts of wood working tools and machines the only one that'll be any use building this is the drill press. So I'm hoping someone will be able to machine the plate for me when the time comes?

Thanks :)
