      Hy there,
      Scraping off 0.013" on the whole length of the bed will drive you
      nuts, try the planer, measure twice and cut once.

      Be careful with the holddowns, I once watched a guy shaping a small
      lathe bed. He flipped it over on a pair of 1-2-3 blocks, cut the
      stands to equal height with the shaper and then, he flipped it back
      over again.
      This makes setup easier. He used holddowns in the middle of the bed on
      the cross braces (4 or 5 equally spread over the whole length) and
      small jacks underneath to push the bed up again.
      If this does not work (don´t hesitate, you got a few more cuts to get
      it right...), junk the bed and buy a new one. Cut the 90° guide in the
      same setup. Try to match the saddle by equal cuts to the left and
      right of the bed. Don´t forget you have to shorten the cut by a factor
      of 0,707 if you cut in a 45°angle. To see what you do, make a sketch
      which is scale 10:1 and the try to draw and measure toolfeeds and
      angles. Please do this in advance.

      Cheers,
      Johann
