I am bilingual in measurements I apologies for the mix of inches and millimetres
Step 1: Tools and Materials
Shed frame off cuts (63x38mm Stud).
Offcut of 6" x 1" x 18" shelf
Drill and wood drill bits
Sliding Compound mitre saw with depth stop (shown in picture)
Step 2: Marking Up, Cutting and Drilling
When using the depth stop on a sliding saw it necessary to place a scrap wood spacer between the fence and the work piece to allow the blade to cut at the set depth across the whole piece.
Step 3: Assembly and Mounting
The backboard was then attached to the shed framework at a height so the longest tool was about 0.5" off the floor.
