80/20 Lite for framing

[rjweng91]

I am looking at building my machine out of 80/20 aluminum but I was wondering if it would hurt to use the lite version of the 80/20? I plan on milling aluminum with my machine so I wasn't sure if that may not be rigid enough? Since the lite version has hollowed out corners of the extrusions.

Thanks
Bob

You're probably better off going with the standard stuff as it will provide better rigidity and damping...
