You can make your bike rack to suit how many bikes and cycling gear you need to store. We had our timber pre-cut at Bunnings to these lengths:
45mm x 90mm x 820mm pine x 6
45mm x 90mm x 1000mm pine x 2
45mm x 90mm x 625mm pine x 2
With your base frame square, use the 9mm drill bit to pre-drill through the 625mm timbers into the longer timbers. Use two bugle 125mm screws in each corner to secure the base frame together.
Simply repeat the previous two steps to make the top frame. Build a rectangle out of the two lengths of timber. Using the same 9mm bit, pre-drill through the longer timbers into the shorter timbers. Secure the frame with 2 x 125mm bugle screws in each corner.
Next you need to make a mid-rail, which will be used to attach the peg board. Measure the height of the pegboard, ours was 445mm. Then transfer these measurements to the longer side vertical timber on the top frame. These marks are the fixing point for the mid-rail. Put the mid-rail in position, make sure it's square and use the 125mm bugle screws to screw it into place.
Lay the peg board on the top frame, make sure it's flush with the top of the frame and the mid-rail. Use the 20mm screws to attach the peg board to the frame. Don't worry if the board burrs where you insert the screws, these can be sanded back later.
The galvanised pipes are what will hold the front wheels of your bike, so make sure you space them the right distance apart. Place the top piece of 625mm timber onto the bottom frame and measure and mark out where you want the pipes to go. Mark a quarter of the way in (205mm) and three quarters (615mm) of the way in. Transfer these measurements onto the bottom frame with your pencil and T-square.
