A lot of carpenters can build stairs. Very few can teach others how to do it as clearly and concisely as this gentleman. Thanks for a very useful tutorial.I've watched a million videos on this topic and this is the only 1 that has the simple trick of clamping a board to the square. So simple yet so brilliant! The entire video was great and very informative! Thanks for the tutorial.I followed your instructions to the letter and my stairs turned out perfectly! I can't thank you enough for passing along your wisdom to those of us who need it.
