No. He does nothing that couldn't be done with a packing piece and loses the advantage of its being flush.
I cannot remember seeing a video of Paul Sellers, where he does not mention that he has been woodworking for 50+years and/or he has taught thousands of students to do "anything" that way - so he knows that the method he is teaching works. I think that this kind of reasoning is not bulletproof. I can find a person, who has been trimming boards to length on a chop saw for 50 years (if any chop saws were produced back then), so that person can technically say that he has been woodworking for 50 years, too. I have been playing piano for 22 years now, but anyone who is training for a professional career as a concert pianist can easily outperform me in 4-5 years. So a sheer length of doing something for a long time or even doing it 8 hours a day / 6 days a week does not give automatically the best methods for everything.Sorry Tibi, Well I looked at it and he didn’t convince me at all in fact I would dare to say he’s just plain wrong. If no other reason than doing it the other way you will not damage your tools on a big lump of metal just where you’re working. And why wouldn’t you want to support your work against the edge of the top – forget whether the bench has an apron or not.
Edit. Wrong was the wrong word, it’s a subjective matter I’m sure neither of us would ever convince the other!
Personally, I think that Paul Sellers is a very competent woodworker with a great amount of experience and he is better than I will ever be, but doing something for a very long time and teaching it to others does not mean that it is the best or most successful method or that someone with a shorter woodworking experience could not come with something better. Some other woodworkers are also prone to tell in every video that they have been woodworking for xy years.
There are things that are objectively better and everyone will agree like chopping a mortice with a chisel instead of a drawknife. And some things are just subjectively better and are prone to personal preference, like what is the best sharpening method question or what bench height is ideal.
I like it more if someone shows that he does a method the way that he prefers for whatever reason, instead of telling that he is doing this for 50 years and implies that it must be the best.
