right, i've finally too jazz's drawing and re-drew it back in to sketchup. i couldnt get on with rhino, its possibly something i'll go back to as i'm aware sketchup isn't that great for actual cnc work.

any way here it is

all colour coded as previous designs, the white flat bits are 50 x 5mm flat bar.

travel is around 450mm x axis, 578mm y axis and 100mm z axis.

i havn't worked out how much steel is used here, but i know already it's going to come in well under the 2 lengths now.. but as a trade off i've gained 50x5mm flat bar so that total cost of the steel as i said before will be £90. i'm happy with that and i still feel it's going to come in under my £1k budget.

i think it's time to start clearing the garage up a bit and think about ordering the steel :D
