Wow, your the exact type of person I'm looking for Neale. Thanks a lot. As jazz said this could save me time and £. Again thank you.

During my research I found that the yokels think aluminium extrusion is some sort of sex toy. (no joke). That's why I want to go for a steel construction plus the fact that I can weld. (when I say weld, I mean melt metal together so it looks like a stick chewed by a dog)

What size steppers are you running and is it 240v?
