Thanks for posting, I enjoyed watching that.
Couple of tiny points. The article suggests that the toolboxes at Barnsley are floor standing, that's not entirely correct. There are floor standing toolboxes, but there are also wall hung tool cabinets like this one in Oak,
Incidentally, despite being opened and closed several times each day for many years, and carrying a substantial load hung off the hinges, the shut lines on those doors would still put a BMW to shame!
It's also worth pointing out that the tool cabinet featured in the article isn't a particularly complex project, it's hugely laborious and it was built with great attention to detail and rigorous application. But at the end of the day it's all straight lines, right angles, and basic joinery. I'm not disparaging it, the end result is both beautiful and useful. However, it's an odd choice for an apprentice piece, as it would eat up hundreds of hours of precious training time without really expanding the apprentice's suite of skills beyond basic rectilinear furniture. Personally I'd have thought a much smaller project that still incorporated multiple drawers, doors, etc., would be a better stepping stone for learning, as it would deliver all the same skills but free up enough time to also tackle the mysteries of say jointed chairs or veneering.
