|Is your underpinner a blue one – Minigraf, Alfamacchine or AMP?
Whatever the model or age, you can upgrade the top clamp to take the unique pliable polymer top pressure pads. The pads come in three grades. Blue for softer wood, 9463
, translucent for medium wood, 9464
, and black for harder wood, 9465
They shape themselves to the curvature of the profile, can be swapped in seconds and are easily washed clean of errant glue. If your top plunger has a magnetic bottom face, then you will need just the steel pad holder, 9462
. That, plus all three pads, is just £45.75 + vat.
