03-04-2025 Q&A: V-Bits vs. Engraving Bits, Two-Sided Cutting, and Reducing Tear-Out

In this Q&A session, we covered a variety of topics, including the differences between V-bits and engraving bits, techniques for two-sided carving and using zero planes, and strategies to reduce tear-out when cutting zigzag patterns in poplar. We also discussed creating 3D tabs, working with diamond drag bits, and best practices for carving statues in Aspire.

Key Tips Learned in this Q&A:

• V-Bits vs. Engraving Bits: Engraving bits often come to a sharp point, while V-bits may have a small flat at the tip. This can affect carving depth and detail.
• Two-Sided Cutting and Zero Plane Usage: The zero plane can help eliminate unwanted seams when working on double-sided projects.
• Tear-Out Prevention in Poplar: Using a compression bit and ensuring the plunge depth reaches the upcut portion can help reduce tear-out.
• 3D Tabs for Double-Sided Projects: Copying tabs to both sides ensures better hold and prevents breaking during the cutout.
• Rotary vs. Two-Sided Carving for Statues: Rotary carving is ideal for reducing undercuts, though it may require different software like DeskProto for efficiency.
