Maybe with gusseting, it would be fine. And I will admit some of the older teams make some great bases with the 3/4" tubing. However, to all of the new teams out there, you probably do not want to try this on your first bot. It works but you need to be well versed with stress analysis. Also, I suggest you have plenty of welders as I believe that you will have many more joints to cover. If, after reading this, you new teams are still confident on using this for your frame, Good Luck.
