Paul -- yes, I had lowered the smaller leg.  I think I just landed on a weak spot

Brian --  Is there any way you can post pictures?  I have a sense of your fixes but I got lost around where you describe how you lower your table. :-/  I have enough of an idea from your post that I think I can try a few fixes.  Did you keep the leaf for the table?  Or did you go for a solid table?

(I don't think this forum tool has a place for file uploads -- there's an idea.)
