Making Our First Cut. Clamp the veneer until it is dead flat. Use a square to make sure the edge of the MDF straight edge is perpendicular to the cutting base board. Start the veneer saw on the far end, hold the edge against the face of the straight edge for a 90 degree cut (very important). Draw the knife back applying only moderate pressure. It will take several strokes per layer of veneer... After grooving the baseboard on the final cut, you will want to reposition the board so it won't pull the knife on the next series of cuts... The saw cuts best on the pull, so don't try pushing it for the cut. Also, learn how to properly sharpen the blade & always keep it sharp !!! You should normally cut the end grain first, then flip & cut with the grain ...
