Okay I am working on a project to see if I can make these things and make a profit. Long story short either the two side or the front and back have to use BENT PLYWOOD or BENT SHEET GOODS at any rate.

I have been picking over my shop for standard plywood, Luna, and MDF and modifying them to work. The closets I got was sheet of luna I would run through my deWalt planner to knock off the front and back wood. What I end up with is bendable but very thin and it cant be finished except for a solid paint as it looks awful

I even tried relief cuts on one side of plywood and its takes way too long and doesn’t really bend much.

I was looking all over for BENDABLE PLYWOOD and WONDER WOOD and any place I found their website had a very poor description or I just didn’t trust what I found.

I need something @1/4 think that will bend SHORT wise. i.e. bend along the width not the length . SO if i had a 12 inch by say 30 inch section it should bend across the 12 inch width.

Does anyone have any experience using such tech and products and do you have a source>

How about a piece of panelling with the luan side out?

What sort of radius are you trying to achieve?

I’d think that those drawer fronts and tops are either steam bent, or bent laminations. As far as a back goes, I’d definitely do bendable plywood to keep it simple.

I can’t help you with a source, but bendable plywood does exist. Its feature that allows bending is that the grain runs in the same direction in all of the plys. I have about 1/6 of a sheet in the shop that’s been lying around for about 30 years waiting for something to use it on. I went out to see if I could figure a minimum radius, but it’s in the back of a bunch of boards. I can say though, that as I recall working with it, it could definitely handle the radius of those pieces in your photo.

I’ve never done any kind of work like that, but that is awesome. It looks like some dr. seus stuff. How do you know what to level or square your work up to. It seems like it would be a nightmare to fit the drawers, etc. There definitely is an art to putting some odd ball stuff like that together.

Yes some call it Dr Suess stuff but generally they call it whimsical!!! I am making research piece right now and it is a nightmare. The little guy siting on the girls lap is the size and type i am doing. The draw fronts weren’t all that hard it was just 3/4 set at an angle on the draw front then i shaped them with a couple of different sanders. IT IS A NIGHTMARE to get it all to line up right as well.

I wanted a rounded back but that is proving to be too much of a head ache… I will post what I came up with when done.

I can do with out the toped TOP and back I think. The round concave drawer front on the bigger one that has to be mounted pressed laminates of wood. I can NOT do that here.

How deep and how far apart where the relief cuts and what thickness of plywood did you try? I’ve seen projects where they made 90 degree corners with bent 3/4” plywood so these more gentle curves should be relatively easy as long as you make enough cuts and they are deep enough. To make the process efficient, you might need a jig or CNC machine. Either way, it is going to be labor or at least time intensive, so if you want to make a profit, including your time, you’ll probably have to get top dollar for them.

The cost of bendable plywood might really dig into the profits, It looks like if you start with wide enough material you could band saw much of what you think you need flexible plywood for,just kiln dried construction material would do the job.

A good plywood dealer will be able to get bending ply for you—it’s available in several thicknesses—3/8” is maybe the most common (and the one I have used the most)—- but 1/8 and 1/4 are available, too—- and in both 4×8 (bends into an 8’ column) and 8×4 (bends into a 4’ “barrel”).

1/8” door skin is also a possibility if the radius is large enough (your project looks very do-able with 1/8” ply)

Thin lauan door skin material can be bent and
laminated over a form. I’ve used it to make
the forms for laminating curves in a book press
I have. Even ordinary 1/4” ply can be bent
and laminated in forms.

For solving this problem with as little fuss as
possible, bending ply is your product. I’ve
used 1/8” Italian bending poplar and 3/8”
“wacky wood”. Both work well and neither
is very expensive. You’ll be amazed at just
how easy using the right product makes
achieving these bends.

People here complain all the time about not
being able to buy plywood from a specialty
dealer in their area. I’m fortunate to never
have had a problem because I live in a major
metropolitan area. I just call a plywood dealer
and ask to speak to a salesperson.

Cant you cut strips from whatever wood you have on a bandsaw and glue up the pieces?

Now theres an idea I could do that on curves with an even radius. Take some time but that could be an answer

Now THAT sounds very labor intensive and keeping it smooth and straight during glue up would be next to impossible without a form or jig of some kind to keep it in place. Even a shift of 1/32” in any direction would result in a ridge. I doubt that biscuits would work and you cannot exactly use a standard hand plane to to easily smooth a curved surface to clean up the ridges caused by misalignments. I don’t see how that could possibly be less work than kerf bending plywood.

Note to acute something along theses lines!! The BACKs of the little guy chests and the larger thing side…

the backs of those can be covered with 1/8” ply. it bends pretty easy.
the sides look like the grain is straight through and cut from one piece- 1/8” or 1/16’ ply bends pretty easy

I’ve seen these before, and to be honest, I think most of them are made on an assembly line of sorts, where the bending forms would be readily available.
I think most of these are laminated bends, which lend themselves best to an assembly line/sub-assembly process, similar to an acoustic guitar line such that you would find in any Asian country.

Notice that almost all the heavily curved lines are painted. Reason for that – covers any laminations.

They are cool, to be sure, but I don’t think you would get much more money per unit than you would with a nice, standard small chest of drawers built with solid wood, painted or unpainted.
