If your cut sections are rolling or not flat, what adjustment can fix this?

Curling and non-flat sections come from surface stiffness and residual stress in the tissue. Warming the block face in the water bath softens the tissue surface just before or during cutting, allowing the freshly cut plane to relax and lie flat on the water surface. This slight warmth increases pliability and helps the section settle smoothly, reducing curling. Other adjustments don’t target that tissue relaxation as effectively. Increasing blade speed can cause chatter or uneven cuts rather than flattening the section. Cooling the block makes the tissue harder and more prone to waviness. Decreasing thickness changes the amount of material but doesn’t address the surface stress that causes curling. Warming the block face directly softens and flattens the surface, making it the most effective fix.
