He is an artist so craft isn't really a factor in whether its "good" or "bad".
Art... in my view is neither good OR bad... it just is.
Craft: though does have "rules" and "guidelines" for quality. Quality in craft CAN be measured, CAN be quantified, CAN be judged and ultimately CAN have a value attached to it.
Maybe the confusion here is that this dude is using Festools and therefore we expect some level of CRAFT to be generated. For most of us in FOG, all we see is a guy scrounging materials and screwing them together which any of us could do with our c12 let alone Ryobi, or Black and Decker or ....
I love stuff like this as its refreshing to me and maybe because I luckily don't have to put food on the table, gas in the truck or kids through college with my craft... or more likely crap. Again, this is ART not CRAFT and just because this guy has the income to buy Festool doesn't make him a master craftsman.
Seeing that he is a student at the Royal College of Art in London though does give me the impression that he is receiving a quality education with possibly "mum" or "dad" paying the way for him to make a "statement". Notice I didn't use the word "furniture" though he might us that word as well. I would also give him some slack for just being a young student at RCA. As we all were at one time.
A very wise design professor wrote on the "chalkboard" on the first day of class. "Design is not Art"... and it liberated me from thinking that somehow, somewhere some muse would appear to show me how to create some beautiful piece of graphic design. What a bunch of shit. Design is Craft and Craft is something that is learned. Just like learning how to hand cut dovetails you have to do it just like any other skill of learning a trade or craft. I am a total amateur but what I bring to limited set of skills I have WITH my Festools is my background in design.
Sorry... I don't mean to sound academic or condescending or presumptuous. I am humbled by seeing the simplest of skills done by someone that has worked the trade for years. More importantly, it puts me in my academic place by being told, "You think too hard about what you are trying to do" rather than "Just doing it".
This guy is an artist and not a furniture maker. Just because he uses Festool doesn't put him in the same class as you other guys that can do it with one eye closed... well maybe "both" eyes closed if you are using Festool
