   mr. creek,

   "holes" equal to the diameter of the tenons sounds good.  i think those 14" thick wedges will seat just fine.  post some photos when you're done.

   Not exactly sure what you're asking, but hope this will help. If your legs are 2" in diameter, and you want a shoulder, that would make your tenons somewhere in the 1-1/2" range. Make the holes in the seat the same size as the tenons - this should be a snug fit. When you wedge them, just make a saw kerf - nothing like 1/4" wide - and drive the wedge in with a little glue, making sure it is perpendicular to the direction of the grain in the seat (so you don't split the seat). 

   If you want a wider wedge for esthetic purposes, cut a tapered slot for it just shy of your final desired width at the top. Make sure the wedge is not too long - you don't want it to bottom out, you want it to spread the "ears" of the tenon. By "too long", I mean the taper should stop the wedge before it bottoms out. I usually do this by cutting the wedge to fit the slot snugly with 1/4" - 3/8" travel left between the bottom of the wedge and the bottom of the slot. You should leave the wedge long enough so you can trim off the excess flush with the top of the tenon once it's fully driven in.

   Everything fits, until you put glue on it.
