Topic tags/keywords: cnc wood bending

I wanted to make a similar design however I am new to woodworking and I was stuck in what was used for the front. Is this a wood bending technique or is this CNC? I ant figured out how they got such a big piece of wood to bend as one piece

welcome to the forum.
no CNC involved – just simple bent lamination.
easy to do – just glue a few pieces of thin wood together in a form
and cut to shape after it sets.
YouTube: steam bending and lamination bending.

You could probably do that with hot pipe bending too. If you have a propane torch and scrap metal pipe you already have what you need, if only doing one that probably cheaper and easier.

What looks like plywood is actually two thin pieces glued together over a form. It’s called bent lamination.

It just so happens that I have a youtube video on how I did it for a bowarm morris chair.

Could be 3/8” Bender Board or sometimes called wiggle wood, or bendable plywood.

DB – what tools do you have or have access to ?

you don’t have to make a complicated steam box like so many show
on YouTube, etc. many folks use a piece of PVC pipe and a steam source.
whatever you have access to and what works for you.
I used my electric cooker to bend some 1/4” red oak which served my needs.
softer woods will bend much easier than hardwoods.

Love the simplicity of that John!

Problem is how to prepare the bacon while waiting for the wood to soften…

There is also a product called 1/8” bending birch.

Below you can see how easily it forms a bend

You take 3 or 4 layers, put glue in between each layer, then clamp it all tight to a form.
Or you can make a 2 part form and sandwich it in the middle.

Clamp the block together.

DB – understand that when steaming some “plywoods”, they could actually delaminate.
only solid wood should be steamed, in my opinion.
if you have access to 1/6” thick wood, laminating to shape with glue and clamps
would be the most recommended.

John, are you inferring that I meant to steam bend these 1/8 strips ?

The 1/8”, I mentioned above, is perfect for laminating together, no need for 1/16th
Have you ever used the 1/8” birch?

LeeRoy – no not your post. (of which I agree with wholeheartedly).
in post #4, the O/P is referring to the project being made out of plywood.
then we started talking about steam bending.
I did not want the O/P to think that general purpose plywood could be steam treated.
(maybe some can, and some can’t. experimentation would have to be involved).
and yes, I have used 1/8” birch in model making – in the flat form. never bent. (I like it).

One can also buy bending poplar plywood, which will go down to a 5” radius bend.

And luaun plywood, as well.
