1. Cut four frame stiles
to size.
2. Cut six side frame rails
to size. Cut 3/4" long tenons
in each end of each side frame rail. Rout or cut a 1/4" wide by 3/8"
deep groove
in one edge
of four side frame rails. These will serve as the top and bottom side
frame rails. Rout or cut a 1/4" wide by 3/8" deep groove in
both edges of the other two side frame rails. These will serve as the
median (middle) side frame rails.
3. Create two side frame sets consisting of two stiles, one top
side frame rail, one bottom side frame rail and one median side frame rail.
4. Lay out the side rails on the stiles so that:
- The lower edge of the bottom side rail is flush with the bottom
ends of the stiles.
- The outside edge of the top side rail is flush with the ends of the stiles.
- The median side rail is evenly spaced between the top and bottom rails.

Good
idea:Make the mortises about 1/16" deeper than the length of your tenons
to keep the tenons from bottoming out in the mortises. |
5. Mark the stiles for
mortises.
Cut mortises in each stile where indicated. Rout or cut a 1/4" wide by
3/8" deep groove in the inside edge of each frame stile. The groove
in each stile should run from the top of the bottom mortise to the bottom
of the top mortise.
6.
Dry fit the side frames and check each one for square. While you have
the frames assembled, determine the panel size for each opening.
Measure the distance between the inside edges of opposing stiles and rails
in each opening and add 1/2" to each measurement. Adding 1/2"
ensures that the panel can't move enough to leave any gaps, but still
has enough room to expand and contract without distorting the frame.
7. Cut out the panels from your 1/4" stock. Remove one of the stiles from
each dry-fit. Slide the panels in their respective openings and reinstall
the stiles. Check the assemblies for fit and square. Make any necessary
adjustments and glue the assemblies together.
