When performing the cut-out test, at what distance should the gaff be pushed into the pole?

• A. 1/8 inch
• B. 1/4 inch
• C. 3/8 inch
• D. 1/2 inch

Answer: (B)

In a cut-out test, you probe the wood at the cut-out location with the gaff to gauge the wood’s condition—how hard or soft it is and whether there are signs of rot or voids. Pushing the gaff in about one-quarter of an inch provides a controlled, repeatable bite that reveals softness or weakness without creating a large, unnecessary cut. If the gaff goes deeper than a quarter inch, that’s a warning sign of decay or internal voids and the pole may not be reliable. If it barely penetrates, the wood is relatively hard, though you’d still inspect for other issues. This quarter-inch depth balances getting meaningful information with limiting damage, which is why it’s the recommended depth.
