When it had weight in it, it wasn't too unstable but it didn't have much of a margin for any movement. The fix took me about 10 minutes of cutting and 10 minutes of welding, and now it can't move. Also for an added measure, I have bolts to mount the bottom of the burner to the frame of the brewstand. As much as I have been taking this thing on and off, I haven't mounted those yet though. Now I just have to pretty it up a little bit.
