In this instructional video from Hardscape Training Canada, Kevin demonstrates the process of drilling, wedging, and feather-splitting a large stone using proper tools and techniques. The video starts with Kevin introducing the wedging feathers from Micon Stone Tools and selecting a Hilti hammer drill for the task.
To begin the process, Kevin highlights the importance of safety gear such as knee pads, hearing protection, eye protection, and masks due to the creation of silica dust during the drilling. He then marks the locations for the holes on the stone, ensuring proper spacing and depth of about four inches to accommodate the wedges.
Kevin proceeds to demonstrate the insertion of the wedges and feathers into the drilled holes, making sure the wedges protrude sufficiently for effective splitting. He emphasizes the need to drive the wedges evenly to create the required pressure across the stone. As the splitting process commences, he points out how the pitch changes as the wedges are struck and how pressure needs to be consistent across all wedges.
Throughout the demonstration, Kevin adjusts the wedges as needed to maintain even pressure. He guides the viewers on how to listen for the cracking sounds indicating successful splitting and achieves a satisfying clean split on the stone. This technique can be applied for splitting larger stones or boulders using wedge and feather methods effectively.
In conclusion, Kevin showcases the results of the stone split and mentions the applicability of the technique for various hardscaping projects involving large stones. His detailed explanation and hands-on demonstration provide valuable insights into the process of drilling, wedging, and feather-splitting stones safely and efficiently. Viewers are encouraged to apply these techniques in their own projects for achieving clean and precise stone splits.
