Planning and build of my "8020" aluminium CNC Router

[Tom]

I think the cold drawn steel will help a lot with stiffening up the bed as well if it is well thought out. I am hoping to build it once and use it lots so I think over engineering now rather than a catch up job later will serve me well. are you using the 6 runners on a block style or a different version Tom? Have you used them on all of the axis as well?

The rails were actually surprisingly floppy. The X are 50x6mm section. Y are ~30x6. The Z plate is 210 x 125 x 6. I think I've got Y and Z steel left over if you're interetsted - you're welcome to some / all of it for cost + postage (minus a bit because it's going no-where at the moment!).

There are some pics attached to give you more of a flavour of what I did...
