DIY Doweling Jig
- 1). Make a small dot with a pencil 3/8 inch from the edge and 1 inch from the end on one of the pieces of wood. Repeat on the other end.
- 2). Place the tip of the 1/2-inch bit on the dot and tap it with the hammer to create a small divot. Repeat for the other dot.
- 3). Place the 1/2-inch bit in the drill and bore straight down through the board using one of the small divots as the guide.
- 4). Remove the bit. Put the 3/8-inch bit in the drill and bore the other side of the board using the other small divot as your guide. These are the guide holes for the jig--make them as straight as possible.
- 5). Run a bead of glue along the edge of the other board. Align it flush along the flat side of the pre-drilled board above the holes that you just drilled. It should look like a sideways "L," with holes centered at 3/8 inch in the overhanging edge.
- 6). Hold the board together for three minutes with your hands until the glue begins to adhere so that the board will not slide when you put on the clamps.
- 7). Put a clamp along both sides of the jig and apply pressure gently. Wait one hour for the glue to dry. Scrape off any residual glue with the chisel.
- 8). Draw a pencil line across the center of the hole straight up with a small tri-square. Continue the line over the top of the jig and down the back of the top edge for an guide to use when aligning the jig onto the 3/4-inch work piece.
