Its very easy. We use some of the official brackets, but we make most of our own - its MUCH cheaper to make your own. 80/20 isn't the cheapest material! We only use 80/20 in limited applications. It's kinda heavy to build an antire robot out of (and expensive). Also, 80/20 frames tend to twist and loose their square.

In 2007 We used four pieces of 80/20 1010 in our drivetrain. It made tensioning the chains really easy. We'll be doing that again this year...

I've also had good luck TIG-ing it. You just need to REALLY sand it down and make sure all the anodization has been removed. Otherwise you won't get any penetration.
