One way to let natural light into a shed is to build a transom window. Whether installing one over a door or in a wall where it is the only window, it is one way to dress up an otherwise blank wall. The key to building a transom window frame is keeping its parts square with each other.

Center on the 3/4-inch edge

Place the 18-inch lumber on a worktable. Draw a line across the centre of the 3/4-by-3 1/2-inch edge. Next, draw an "X" exactly 1 inch from the edge on both sides of the end of the lumber. Repeat this on both ends of all eight of the 18-inch pieces.

Indicate dowel pin location

Draw a line on the top of the 18-inch pieces of lumber to represent where the dowel is to be inserted into the lumber. Dill holes at least 1-inch deep with the drill and the 1/4-inch drill bit.

Marking the long pieces

Place the four 47-inch pieces of lumber on the worktable. Measure from one end and make a mark at 3 1/2, 14 1/2, 18, 29, 32 1/2, and 43 1/2. These marks indicate where the 18-inch pieces will be secured to the 47-inch pieces.

Aligning for dowel pins

Place the 18-inch pieces on the marks from Step 3. Use the lines representing the dowels (Step 2) to mark the 47-inch pieces.

Geting ready to drill holes

Next, stand the 47-inch pieces on their long edges. Draw a line at the centre of the 3/4-inch edge. Then, draw an "X" on the centre lines, using the marks from Step 3 as a centre point.

Drill and insert dowel pins

Drill holes on the "X"s, 1 inch deep, to receive the dowels. Apply glue to the holes and insert a dowel pin into each. Be certain that it "seats" all the way into the hole. Repeat this until all the dowel pins are in all four of the 47-inch pieces of lumber.

Clamping the parts

Apply glue in the holes of four of the 18-inch pieces. Place them between two of the 47-inch pieces and fit them together. Pull the frames tight with the bar clamps by placing one on each of the 18-inch pieces. Repeat this for the other frame and leave them clamped overnight.
