Insert the 3mm wood drill bit into the drill, and create pilot holes in the base, within the marked lines and along the side edges.
Place an old scrap piece of wood under the project wood you are drilling into, to protect the work surface and limit wood splitting.
On the end edges of the 2 x 22mm x 44mm x 250mm vertical pieces for the dowel handle, draw a square (about 3cm x 3cm), then draw diagonal lines from corner to corner to find the centre.
Insert the 22mm spade drill bit and drill a hole in each piece, stopping just before the spade bit breaks through to the other end. These holes will hold the dowel (handle) in place. .
