The upper blade guide on a bandsaw should be adjusted to clear the stock by how much?

• A. 1/4 inch
• B. 1/2 inch
• C. 3/16 inch
• D. 1/8 inch

Answer: (A)

When setting the upper blade guide, you want a small amount of clearance between the guide and the stock as the blade passes. This prevents the guide from rubbing the workpiece and helps keep the blade properly tracked and cool. About a quarter inch of clearance is a common, safe target. If the gap is too small, the guide can contact the stock or blade and cause friction or burn marks; if it’s too large, the blade can deflect more and lose accuracy. The other options are typically excessive or insufficient for standard setups: too much clearance reduces support for the blade, while too little risks rubbing. Start with the quarter-inch gap and test with a scrap piece, making sure there’s no rubbing and the cut tracks cleanly.
