Sawing a Plank
A high-powered circular saw is required for sawing thick strakes (thicker than 3 or 4 cm). Always hold a circular saw with both hands and keep it flat and level on the plank. Guide the circular saw gently along the pencil line, don’t push, but allow the saw to do the work. Run through the following steps:
- To cut out a marked strake from the rough plank the plank must have clearance underneath. Create this space by placing the plank onto a few beams (image 1).
- Adjust the depth of the circular saw so that the blade just protrudes through the plank, not any deeper (image 2). In this way you will prevent the circular saw from jamming in the timber when cutting a curved line (image 3) and (image 4).
- When cutting curved lines hammer a chisel into the saw cut (image 6) behind the circular saw in order to pry open the timber and thus prevent the circular saw jamming in the timber (image 5).
- Always saw on the outside of the drawn line in order to prevent sawing off too much material (image 7). An excess of material can always be removed using a plane (image 8). A plank that is sawn too narrow may be unusable as a result of this.
