This is a must watch video; I'm sure you won't regret watching it even if you have many vices or vises. Beyond the primary focus, you will see an unassuming and highly proficient woodworker with a sense of humor. Mike is also the author of a video on making the Nicholson bench you see here that is published by Lost Art Press.
I have great respect for Mike and I hope to meet him someday. What you see in the workholding video is a more proficient and expanded version of what I learned on my own by spending a year without a vise on my new Nicholson bench. It was really fun to discover all of the things you can do and the techniques are very worthwhile even if you have a vise.
I am an economist and I worry about the barriers to entry to hand tool woodworking, which are considerable. Woodworking is reportedly in decline as a hobby. A video for people new to woodworking about making a very low cost bench and acquiring a basic set of tools inexpensively is a real contribution.
I wish we could convince Mike to produce a weekly subscription video series like Paul Sellers does. I know I would subscribe. C'mon Mike, let's go.
