Mike, thanks. There is. I just hadn't taken a photo of it with it welded in place - it's why I made that bottom plate so long. You can kind-of see the lower brace here. It's some 1.5" angle iron.

Now going completely overboard (and having fun with the welding), I put a 10 degree angle at the top of the mast post so I can just square cut a piece of treated lumber and pad it to support the mast shape. The angle puts that lumber perpendicular to the mast when loaded. I also closed in a through hole through which the wood will be mounted and capped the top (since this will be painted and not galvanized...I can't paint the interior easily so it's easier just to seal it up).
