Step 7Prepare the Railing
iImage Information

It is easiest if you mark all of the cuts and holes on the side rail first. This will ensure, for example, that the drawer glides are properly aligned. I used pieces of blue painter's tape on the rails everywhere I needed to make a mark. Mark lines at 1" in from the outside end (the end with the screw and dowel holes) of the fixed half-rail, on the top and bottom bars. This is where the end of the fixed part of the drawer glide will be positioned on the rail.
Mark the top and bottom bars 25" from one end of the rail. The side rails have an odd number of vertical posts, so you can't cut exactly on center. Identify (with PostIt notes or tape, if you wish) the shorter 25" half as "moving" and the longer (27-1/4") half as "fixed."
