As a former bench joiner, i understand just how hard assembling a frame with 82 biscuits is - very great deal of skill on show here

I doubt a woodworker used to naturally grown wood and its special needs in terms of directionality and joinery would call a plum and level built plywood box with cookie dowels, dados and screws "expertise" to be honest. Look at the inner back veneer alone, no matter how much stain there was put on, it's still just plywood showing, no effort whatsoever was made even tryna make it look like anything better than ply. It is reasonably well built and looks ok, but expertise ...? Expertise would use modern ways to understand statics and engineering, wouldn't it? Even the metal in the shelves would not be necessary, at all, with a third or even a quarter the width ply sheets turned into hollow box form sandwich shelves, no matter foam or just some flimsy sticks used as an inside divider - at least about a third of the overall weight would have been spared this way, which would count to about a third of the material used "unnecessarily", not to mention the ease to move and position a giant piece like that ... You got to fix it to the wall anyway in this height range, so You do not need any excess weight to "stabilize" it via gravity, do You? Weight as well as the distribution of the very weight inside a product is as important as its different materials combined to maximum strength are. Every part is supposed to take over at least two special tasks in terms of statics, better three tasks, and it gets into "expertise" engineering to reckon this and use the different material's strengths and weaknesses to produce a superior system outa "normal" materials by combination, at least in my book.

@@manfredschmalbach9023 After over 45 years in the cabinet trade, 36 years with my own shop, I have found that there is a formula for bidding. There are 3 parts: materials, time (labor), and quality (labor). You only let the customer control one of these. You have no idea what restraints he had when starting this project. Box shelves would have taken a lot more time to build and no difference in the end result, except his are heavier. Well, somehow they got it into the office, everyone is happy, and he got paid. So the back doesn't meet your spec. Look at the installed pic. All the back is covered and will be until the buyer retires. And not even sure what you mean by making plywood look like anything other than plywood. It's plywood. Plywood will always be plywood. It will stain differently and have a different sheen when finished. Just how much time in the finishing process would you take to make it what you want? And then all your work gets covered up.... Given an unlimited budget, he could have had the shelves made from cast aircraft grade waffle cored aluminum and then veneered them. He could have made a stile and rail back with solid panels. He could have ....lots of things. But he didn't. I think his design was maybe overbuilt. I may have built it simpler. But the robust construction will keep him from ever getting a call a year from now that the shelves have sagged 1/4". That's the nightmare he has avoided and can sleep at night knowing he won't get that call. To say that this didn't show expertise reminds me of the Fine Woodworking mag I used to get. If you didn't use sustained growth all solid materials (mostly exotics), hand sawn, hand jointed and hand scraped smooth surfaces, all mortise and tenoned or dovetailed together (no fasteners, God forbid), finished with 15 coats of custom mixed shellac, french polished surfaces, all worthy of a museum or expensive gallery in New York, then don't bother, it's not worthy of consideration. But some of us need to make a living at what we do and to not say what we do doesn't take expertise is, well, may I say it, arrogance? I have never chopped a dovetail in all my years. It's part of that bidding formula. But some of my customers say what I do is magic. Is that expertise? I'll let them decide that and leave others to make a living as they can, without leaving snarky comments.

@@AffordBindEquipment I already wrote, and gladly write again, how it was reasonably built and does look OK. I have no idea what restraints he had, You're absolutely right at that point; it just does not matter, at all, when the "expertise" word is discussed in context to what You saw, and what I saw, in a random KZfaq clip. Honeycomb core, not from aluminium of course, but from bloody card board, is a standart fill-in used often for sandwiched box shelving when partial dividers like the aforementioned "sticks" would lead to an inferior product by not distributing the load evenly. Even bloody IKEA does it because it is so much cheaper and leads to a so much superior product. It is *waay* cheaper to use honeycomb cardboard and thin veneer or ply than use mahussive ply bricks, that's for sure. Which would open a wide gap in Your endprice You could fill with expert work. It would need some expertise to understand and subsequently build with those materials and not make a mess but a product, though. Calling a well built box shelf and the iron-ply-joke he showed "equal" in terms of load bearing, though, would only make me think You never ever have built a proper box shelf either, besides of never ever having cut a dove tail. Not a problem, don't get me wrong! Dovetails and boxshelves are completely unnecessary, as well as craftsman's expertise, these days, when everybody wants everything in China-quality and for Bangladesh- or Burundi-prices (... and does even know a guy who is a laywer, in terms of "nightmare", should You be risk-prone enough to really _build_ things instead of just trade them.) IKEA has enough expertise in their crap for all the friggin bookshelves the world will ever need. Only thing I was referring to was the expertise-word I did not see being met in the videoclip it was used for, at all, and only "in my book" of course, as I wrote, too. You might call loosely laying an "enforcement" right into the neutral axis of a system You plan to seriously load "expertise", I do not, and I won't even after a lively debate with people making a decent living of putting "enforcements" right into the neutral axis before calling this "expertise", sorry to break this to You. Oh, and in terms of looks: there are positive stains and reverse or negative stains available. Try it. Treat parts You cut from ply with both and compare. I'm sure You'll see it. "Expertise" would start in knowing the different outcomes of different sequential uses of both on the same part. It's not necessarily needed, though. But why calling a randomly stained random ply brick "built with expertise" then ...? See? Have a nice day

@@manfredschmalbach9023 In the video he doesn't even have time to finish it himself, so he actually overspent on time.

The front facia obviously adds a lot of strength too. This design seems to originate with the "Mr. Sawdust" radial arm saw table which is famous on the internet for radial arm saw collectors. He specified that the steel rails be glued with epoxy, and not wood glue. Epoxy binds to steel and wood equally well, whereas wood glue shrinks significantly and doesn't remain attached to steel at all. Although epoxy could ruin the wood permanently if spilled, so it might be best to skip the epoxy and just trust the wood glue.

Can't agree more. Sumptuous. Only one criticism: I don't think he should use power tools at that sort of speed: one day he might get quite a nasty injury.

Me too. IDK where to get mahogany plywood, though. Been to all of the "woodworking" stores around.

Hey Ken... that is a great idea! I've made tons of hollow core doors using the same process, and they are bullet proof!

Thanks aucourant!

Alan Runfeldt It is basically a variation on what is called a flitch beam. Tried and true technique.

It takes more than the right tools.

Hi Michael I was wondering about the "ribs" in the plywood... are they made of STEEL? or do you recommend me other material...?

@@lmtz007 steel works and is cheap. Aluminum is lighter and not as strong, but still works. Square stock works the best, but can add a lot of weight. Your best bet is to buy some of different materials and test the strength. You'll be surprised at how much a simple piece of flat stock can hold! I literally drove my dad's 4 ton dually over a 4' shelf with steel flat stock in it!

He stole the shelf supports!?!?

What did he put in between ply boards to support shelves?

ReaperXC it kind of like 1/2 or 3/4 iron flat bar, excellent idea

Thanks Mr. Tread!

Yeah, their names were Forktruck and Backhoe.

Yeah, that thing was a load. Wow.

8 guys could probably move that thing. A little.

They use robots for that now.

Crane.

Thank you!
