Simple Machine (help and advice needed)

[Gregor]

Well after reading through most off the build logs I thought I would give it ago,I have to say that not really knowing a lot about electronics and stepper motors I get confused easy.
My goal is to make a simple strong build which will be able to cut hard woods and aluminium at a reasonable speeds, I only have room in my workshop for a machine off 900mmx800mm I have done three design off the base A,B,C which I will upload, my abilities on sketchup are also pretty limited so I hope you can make them out ok.I have done the design using 60mmx60mmx4mm box which I would have to buy but I do have 50mmx50mmx4mm box in stock and if I could use it it would save me a few pounds. I can weld ok and hope to weld most off the build and limit the amount off holes to be drilled.I haven't designed a gantry yet as I wanted to get the base right first.My build budget is Around £1500 mark.
All help will be gratefully accepted
Cheers
