Build log at last

[Gregor]

I welded this frame for a friend about 6 months ago but he has moved to a new house which doesn't have a garage so he give it back to me. Its made out off 60x60x4 box and the end plates are 10mm plate.He was going to use it to cut hard wood and really that is what i will be using it for but if i could cut aluminium every know and again it would be a bonus.The size of the base is 1000mmx700mm. After reading some other build logs i am not sure if i could get away with using one ball screw or do i need 2? The gantry i hope to build out off aluminium . I haven't bought any parts yet
Thanks in advance
