That's a good start, but at first glance, the gantry looks a bit tall for the size of the supporting columns. Since you're using sheet metal a U-shaped piece could be added to each column - similar to what you have done, just bigger. This would increase the width of the machine, but add a lot of stiffness.

What is it you're planning to use as the base of the rails for the bed? In the drawing it looks like just a thin metal sheet, which I'd advise against as it's unlikely to be sufficiently flat for the rails to perform well.

theres an extruded frame work under the rail and sheet and I was gonna put another 4mm sheet on the underneath...
ive spent the last two hours chewing over wether to go for a welded affair. so possibly be posting a mk2 soon ;)
