I just saw this video on workholding on the workbench. Just over half an hour long. Presenter is Terry Gordon. Video is full of common sense solutions and very good explanations, as you would expect from Terry.I thought it was well worth the look. https://www.youtube.com/watch?v=82juh2OdG7U(usual disclaimer - I have no business affiliation with HNT Gordon and have not been asked to promote this)
