How to realign an Alfamacchine underpinner

Overtime underpinners can become misaligned meaning you don't get the best join. Follow these steps to fix this problem.

  • Step one

    Loosen the underpinner fences with a hex key.

  • Step two

    Place the Set Square on the underpinner. We'll be moving the V Nail head along the centre line.

  • Step three

    Make adjustments by moving the set square in line with the nail head. This ensures the fences are in the right place.

  • Step four

    Once happy with the positioning keep the set square in place and tighten the fences with the hex key. 

  • Step five

    The problem should now be fixed, meaningly you'll get the perfect corner join every time.
