I gotta start off by saying I love the Cactus! workshop channel, its full of quality projects and sets the standard for videography. In this video he designs and creates reversible bench dogs that can be easily raised up for when being used or simply turn them 180 degrees and they will drop flush with the table. He also makes some handy collars to go around the dogs to allow for a wedge style clamp. I also like how he incorporates a little metal working into the project, a mini metal lathe is on my short list for new shop tools;)
