Lapping the Backs of the Blades
Lapping the backs of vintage chisel blades is an essential part of their restoration, as it helps achieve a flat, smooth surface for optimal cutting performance. Start by placing the chisel blade flat on a coarse stone, using circular or figure-eight motions to grind away any imperfections and create a consistent flatness. Progressively move to finer stones, such as 400-grit and 800-grit, to remove scratches left by the coarse stone and further refine the flatness of the back. This process ensures that the cutting edge of the chisel will make full contact with the material, resulting in clean and efficient cuts.
When lapping the backs of the blades, it’s crucial to maintain a consistent angle and pressure throughout the process. Using a honing guide can help in achieving this uniformity. Additionally, periodically check the progress by inspecting the back of the blade under a light source. Look for any remaining pits, scratches, or inconsistencies, and continue lapping until a mirror-like finish is achieved.
It’s worth mentioning that the number of strokes required for lapping may vary depending on the initial condition of the blade and the desired level of restoration. Be patient and take your time to ensure that the backs of the blades are properly flattened and polished. Once this step is complete, you’ll have a solid foundation for the subsequent stages of chisel restoration.
