How to tighten a wooden bannister (newel post)

carpentry

enter image description hereHow to tighten a wobbly stair bannister? I tried going in from the basement ceiling, the floor boards are in the way. I tried drilling in a screw at an angle at the base to anchor to the bottom stair, and lets just say I now need to figure out how to extract a broken screw and patch a hole to lessen the carnage. I imagined there is a nut/screw job under the wood that needs to be tightened, but darned if I can figure out how to get to it without ripping up the wood. I could try some glue, I suppose, there is a tiny gap around the bottom, but that doesn't seem like it would last past a few pulls.

I guess you already know that your attempted fix is a fail. One realistic way that such a newel post can be made more sturdy would be to do some re-work to the structure as follows:

A flat metal bracket is made with a round metal post welded to it. The round post (0.75 to 1.0 inches diameter recommended) would extend up through a round hole in the lower stair tread and rise up to a height of 10 -> 12 inches. The metal base plate is screwed up to the bottom side of the stair tread. The center core of the newel post would then be bored out to permit the newel post to be mounted on the projecting round post. (See picture below).
