If you're cutting large pieces of wood, the standard aluminum Q-FENCE may not be tall enough for you.

At this time, in addition to considering another RS-FENCE with a higher leaning surface, you can also consider adding this 6"(150mm) resaw plane to increase the height of the leaning.
This wooden resaw plane is a 6" high wooden backing board about 15 cm high.

Primarily designed to be mounted on the right side of the fence to increase the resting plane of the qorkpiece.
