If you want margin boards, first trim your rough panel so that you can see the edges of the template. Align the panel on your template. Using your compass set to 60mm or an off cut of margin board, mark your panel all the way round 60mm back from the edges of the template. Cut your panel out just outside the line and sand back to give an even edge. Cut your margin boards slightly over length for each edge. Offer up to ensure they are going to fit nicely without any gaps or unevenness.

You need the following tools:

• A work bench with a straight edge to work against
• Some weights
• Masking tape
• Sharp knife
• Metal ruler
• Drawing Compass
• Stelmax glue for joining the planks
• Caulking gun if using margin boards
