Squaring Board Edges with a Block Plane

Video Transcript

"Hi, this is Jon on behalf of Expert Village. In this video clip we'll checking our stock for square. Now when checking end grain for square we're going to take a tri square and place it against the edge of our stock and the end of our stock. We're going to look along this edge and if we see any light coming through or in this case I put a black piece of paper behind it. If we see any color coming through that it means that it's not square. Now on another piece of stock we're going to test it for square and I put my tri square and I see a thin black line on one edge but this edge is totally flat. This tells me that my end is not perfectly square. What I would do then is take my tri square and draw a line right on the edge and I can see that there's a little bit more lumber here than what there is here. Then I would want to clamp it and use my block plane and plane that down onto my line."
