What happens here

Sam demonstrates the process of cutting cap blocks to fit the wall's corners. He explains the distinction between an 'inside 90-degree' cut and an 'outside 90-degree' cut, drawing diagrams on the blocks. For inside corners, a cut side meets a rough side, which is difficult to make flush. For outside corners, two split ends meet. He highlights that cap blocks require scoring both sides and constant rotation for a clean break, unlike regular blocks that can be split by hitting the back. This precise work minimizes material waste due to incorrect cuts.

Goal: Sam explains the intricate process of cutting cap blocks for inside and outside 90-degree corners, detailing the differences and required techniques.
