Manufacturing a weatherboard » Instructions with the portable circular saw

Weatherboard
This application example shows how to cut a mitred weatherboard using an HKC cordless circular saw. This job is a bit of a challenge because a mitre cut has to be used here. Nevertheless, this is one of the most visually appealing solutions for formwork.

    Description

    An HKC portable circular saw with FSK cross cutting guide rail is suitable for sawing a weatherboard. With this combination, mitre cuts can be executed with high repeat accuracy. Since the portable circular saw is battery operated, it is also very mobile on scaffolding.

    Tools/accessories

    Procedure

    • Aligning and securing the rail

      First, the weatherboard is fixed to one side of the wall as usual. The edges are removed from the shuttering boards with a sufficient overhang so that they protrude laterally at least twice the board thickness.
      To fasten the guide rail, two or three small holes can be drilled into the rail. Using these holes, the rail is fastened at the measured position.

    • Cutting a section

      Along the guide rail, the HKC is now used for the first mitre cut through all shuttering boards. (For larger board thicknesses, the TS 75 can be used for this cut as an alternative.)

    • Measuring the angle

      The correct angle, which must be set on the rail, can be taken from the straight mitre cut as shown.

      Measuring the angle

    • Transferring the angle

      This cross cutting angle is then set on the cross cutting guide rail via the sliding stop according to the scale.

    • Adjusting the saw

      In addition, the saw must be tilted. This angle is determined as shown and then set on the saw.

    • Positioning the portable circular saw

      The saw is now placed on the workpiece with a coupled cross cutting guide rail and two stop pins.

    • Cross-cutting

      Cross-cutting can now be executed very easily and with precision. The settings are repeatable for the subsequent cross-cuttings.

    • Assembly

      The cut board is screwed together as usual. If required, a compriband can be applied for sealing.

    • End results

      The result is a clean corner finish for the weatherboard. Note: This corner formation is visually appealing, but not ideal in terms of constructive wood preservation.
