Hi, new guy here

Couldn't figure out where to post this

I am making plans to build a metal cutting CNC router and want something rigid and stable. It will be used to cut aluminum sheet up to 1/2" and table size will be 48" X 60". It seems that most of the DIY router tables I have found on the web are constructed from aluminum 80/20 type of T slot components which for most uses is an easy and clean way to go. But I want a more heavily built machine and expect to build it of steel. I plan to use standard steel shapes such as box section tubing with some brake work (metal bending) for the gantry.

What I am hoping for are some links to builds like mine that are more heavily constructed. Can anyone point me in the right direction to see what others have done? Thanks.
