      I considered the dado head but decided not to since a bigger cutting surface has a greater potential of ripping the stock away from you.  and I have no need to be called 3 finger Charlie.. Right Master Charles?

      Ditto on Rhys's dowel reducing, method, except I used a dado head to cut.

      For the flattening - seems you have a prime opportunity to acquire and learn to use a proper handplane. "Honey, I HAVE TO have it for this project". If you want one that works well out of the box, I'd suggest a lee valley #4.

      > Thought 1, Been there,I used my table saw to step down the dowels, yep sounds weird, but works great.  I created a jug with a v shaped trance, and clamped it to the table perpendicular to the blade.  I used a scrap dowel to test the new diameter by trial and error, test, raise blade, test again, etc.  you very very carefully slide the dowel down the trench twisting it to cut completely around.  cut one blade width slide it in repeat until you hit the fence set at desired depth.   I had a 2nd v block above the dowel to hold it down.  Creates a rough surface that holds glue well.  Not quick, but I did 10 chairs that way, and have had no problems with glue failure. wedge holes, again v grove jig, I used 2 one at a 10 degree angle.  drill hole closest to chair vertically, 2nd at angle with 1/4 in drill.  clean out between them with a chisel.  Wedge holes made, quick and easy.  A 5 degree angle gives you a tighter wedge, but these chairs don't stay together for more then an afternoon.  (Midrealm Royal Thrones) and being easy to take apart was important too, hence the looser 10 deg angle.
      > Thought 2 . If you make more I have plans for frame and panel seats.  these don't completely disasemble like the period version.  on my website  http://www.noonelike.us/~rhys/  Also I have more period arm designs
      > Thought 3  that sucks, been there done that.... two ways I used, very coarse grit palm sander, or I have an electric planer, hand model, that is to wide for my surface planer.  The hand model can be set to desired depth and very carefully cut.  You are still going to sand like crazy, but it takes away some of the pain.  also the electric planer is very useful in the shop, I use mine a lot. this one on craigs list is the same model as mine http://sanangelo.craigslist.org/tls/2301972536.html  Also consider spline jointing in the future http://tinyurl.com/42p48la    Splines are very handy and easy to make clean matching surfaces, the big secret is cut with the table saw in the center of the piece then reverse ends and run it a second time so it is perfectly centered, cut splines after that to ensure a tight fit.  Spline joints done properly are stronger then biscuits.  (grain of spline and grain of piece should be perpendicular for maximum strength)
