We've made our frame for a single bed but you can make yours any size you want. You can have the timber for the side braces, middle support and the plywood base pre-cut at your local Bunnings*. Here's our cut list for this project:
1200mm x 2400mm x 17mm ply board:
90mm x 45mm pine:
*Not available at all Bunnings stores.
Line up the pieces for your frame together. Measure the length of the side braces and mark the halfway point. Place your centre brace on this mark.
Use the nail gun to secure the side supports to the middle brace. Repeat the process on the other side. If necessary, use a square to make sure the bed frame is square. The final dimension of the frame will be 1860mm x 780mm.
Place the plywood base on the workbench, then place the plywood blocks in each corner. For the centre blocks, measure your base to find the middle and place your blocks on either side. Apply PVA wood glue to each plywood block and press them onto the base.
You will need someone to help you with this step. Place the frame on top of two saw horses. Have someone help you lift the plywood base on to the top of the frame. Make sure it's centred and flush with the ends. Secure it by driving the screws into the ends of the frame and the middle support beam.
Before you sand back the surface, putty up any holes where the screws are. Let the putty dry and sand back the whole surface so that it's smooth.
Depending on the look you want, you can paint or stain your bed frame. Wait for the paint or stain to dry before moving it into your bedroom.
