Interesting, but not quite revolutionary. There's been a CNC technique for a long time where a veneered piece of plywood or MDF is put veneer side down on the table. The single piece is cut with a 90 degree V bit just to the depth of the inside of the veneer, creating the box bottom and four sides. The five pieces are folded on the veneer and glued up in nothing flat.

Very cool!

Great way to build boxes! Thanks for sharing.

True, but the $100k CNC you need to pull it off with is a bit of a downer for small scale operations.

Can't see the video if that's what it is, on my phone, but it it's what I think it is, yeah its nothing new, saw it in a jbl video years ago, and another big loudspeaker company video a while ago also

I believe Mark Seaton's cabinets are done that way.

Looks like a simplified version of a lock miter joint, looks nice though. It would make dealing with raw MDF edges pretty easy, do all your baffle cutouts in the middle and then cut the joints so box folds together leaving all the raw edges pointing to the back of the box. Rabbit in the back panel and call it good.

They were doing much the same with vinyl veneered particle board when I was working at Morse-Electrophonic back in the mid '70s. But they used a type of table saw, not CNC.

He could do the same thing by putting a regular saw blade at 45 degrees and just short of coming through the material. Pass all 4 edges over the blade, move the fence to the other side, adjust it so that the blade top meets the tip of the first pass and pass all the edges over the blade again. You'd have a 90degree V groove and you could fold it up the same way.

Re: Guy invents awsome new way to make drawers (speaker boxes??)

actually after finally seeing the video, it does look pretty sweet. why not have a cutter made that is just a V shape, what way you can pretty much do the same way I was thinking, as in the ML video, but with a table saw.
Right now I use a locking miter joint which works okay with MDF(slow going) but not with ply, when everything is lined up I have a complete box with no raw edges, may actually look into having a blade made.

Looks like Pete has kid of the same idea ;)

Re: Guy invents awsome new way to make drawers (speaker boxes??)

The problem with all of the lock miter bits, plywood drawer bits, etc is the setup. Always fiddly and difficult to get right. This is a one pass deal.

Although the real key seems to be not cutting all the way. All joint errors are hidden that way.

Large 90 degree V groove router bits are available. May also work.

Re: Guy invents awsome new way to make drawers (speaker boxes??)

Yeah its a pain to setup lock miter bits. Was also thinking about a v groove router bit, but think it would still be a bit of a chore, would have to make a new bigger router table, or maybe just add a sort of "wing". Looking last night I saw a table saw shape setup with changeable cutters with a V option, some said it's pretty scary with those though with a greater chance of kickback and all. Just writing this I think I'll try the router method first. Another option is to just do you cuts at 45* then glue then to the laminate end to end then fold them up.

Re: Guy invents awsome new way to make drawers (speaker boxes??)

The other underlying problem with this technique is the subtle difference in thickness not only panel to panel, but within panels. Companies that use this technique in manufacturing typically use CNC with a router bit ABOVE the material. That way, any subtle differences in thickness accrue on the INSIDE of the fold.. When you do it as the demo video shows using a table saw, the variance accrues to the OUTSIDE of the fold.

What I'm saying is, if the next panel he tries is 1/64" thinner, he needs to adjust the height/width of his stack. With a CNC and v-bit, you don't need to make any adjustments, the thickness of the ply is almost irrelevant.

FWIW, there are jigs designed to v-notch corners for drawers, intended for small cabinet shops. They typically include a 3-HP router, a large v-bit, and work sort of like a radial arm saw. So you dado a piece of stock (for a bottom), then you run it through the v-cutter device, and then you fold it up. I almost purchased on (Craigslist) that appeared for a few hundred bucks. I should have purchased that thing, it would have been awesome for speaker enclosures.
