Once you've worked out how big you want your corner shelf to be you can take your measurements to Bunnings where you can get the plywood cut for you. Or you can cut the plywood yourself with a drop saw. Mark and measure out your 45-degree mitre joint and cut it. Make sure you're wearing your safety glasses, dust mask and ear muffs when cutting the timber.
To join the two pieces of timber together, we'll use dowel joins. Measure and mark a spot near the top, bottom and middle of the plywood on both pieces of timber.
Place the plywood on its side and use the spade bit to drill the six holes for the dowel. A simple way to make sure you don't drill too deep is to use masking tape to mark half the length of the dowel on your drill bit.
Apply PVA wood glue into the six drilled holes. Insert the dowel into the three holes on one piece of plywood. Apply glue to the mitre join. Join the two pieces of plywood together, making sure they're flush.
Wait for the glue to dry. Put on your dust mask and sand the shelf so that it's smooth.
In the corner of your room, measure and mark where the shelves will go. Make sure the points you mark are level.
Use a stud finder to find the studs behind the wall where you will hang the shelves. Mark the spots where the studs are.
Use the drill and screws to secure the flanges to the studs. Repeat this for all of the flanges.
Place the shelves on the pipe supports, so that they're flush with the corner and the wall.
To finish the job off, screw the caps onto the ends of the pipes. You can also paint the shelves so that it matches your décor or you can go with a more natural wood look.
