To begin this woodworking project, we'll need to cut the oak stock down to the appropriate pieces. When this step is done, we'll need the following pieces cut from 1x4 or 1x6 oak (see the Free Woodworking Plans for details):
2 @ 3" x 69-1/2" - Stiles for sides of mirror
2 @ 5" x 15-1/2" - Rails for top & bottom of mirror
2 @ 2-1/8" x 22-3/4" - Top and bottom trim pieces
4 @ 3" x 5" - Trim blocks
Cut these pieces to length with a Miter Saw or Circular Saw before ripping them to the appropriate widths with a Table Saw.
Before we move on, tilt the blade on your table saw to a 45-degree angle for cutting one chamfer on one narrow edge of each of the four trim blocks. You'll want to cut a chamfered edge half the width of the edge of the stock (as shown in the drawing on page 3 of the detailed drawings you downloaded in the previous step).
For this operation, because you'll be cutting against the grain, do not use your fence to determine the position of the cut, as the stock can dangerously bind against the fence. Instead, clamp a strip of stock against the fence before the blade. After adjusting the fence to the proper position, place the trim block to be chamfered against the stock and then push the trim block through the blade using the saw's miter gauge. Repeat with the other three trim blocks.
While the table saw is set up to cut a chamfer, adjust the fence and cut one chamfer on one long edge of the top and bottom rail pieces. This chamfer will give a nice softened look above and below the glass mirror.
