Question Prefered way to make this part

Hi guys,

I would like to ask for an advice.

I designed my table to have curved sides.
The image of the side part is in attachment.
Length=55cm
2,2cmx2,2cm
Length from left to right is 10cm



There will be 12 on each side of the table.

These sides wont be responsible for holding the weight of the things on the table. Its just design part.

Whats the prefered way to do this part?

Thanks

Based on that shape ....

You have 2 choices:
Cut that shape out a solid piece of wood, but it won't be strong because the grain changes in the curves.... not my choice.


Laminate the shape from 1/16" thick strips in a two sided form with glue and clamps. You can make wider forms than you need and then cut the width to size on a bandsaw after they come out of the forms. This would be my choice.

Welcome to the forum! Add your location to your profile so it shows in the side panel. Add your first name to your signature line so we'll know what to call you.

Is this an apron for the table? Which wood will you use?

I am new to wood working, I have just basic tools like Jigsaw and Circular saw for straight line cuts, electric sander, file, clamps and thats prety much it, I am 24 and I feel like I would like to get little bit more skilled with woodworking.


David I have no clue about wood I want to use. I am on budget of 50 for wood, therefore something cheap that could look good.
I will post the design of the table the moment I get home:)

Woodnthings that bending technique looks good, but do you think I will be able to bend it to this shape without breaking it?

how to bend wood ....?

There are 2 ways woodworkers use to bend wood in tight curves:
Use a hot pipe to bend the thin strips around.

use a steam box to soften the wood:

Here is the design of the table but there is a middle part missing which will hold whatever weight we put on top of it.

I mean it would be prefered to have it just like this. but iam not sure if wood would be able to hold tv on top of it :D

In this case I would definitely use bent lamination as it seems you'll need quite a few of these parts. What I would do is jig up two boards of MDF with a few spacer blocks in the middle and shape it to fit your piece (Like the picture I attached, not one of my jigs but very similar to what I use when I do this.). Since you need a few of these I think it might be easier to glue up a few larger pieces and rip them to the smaller ones you need.



Don't know about this holding a TV however,

It's kind of strange that this line was delivered in that movie of all things. It's still a really good quote, and certainly a dang good thing to remember.

This is the picture with the middle support. IT should hold all the weight from the tv.

so Trix - basically, you are wanting to make the end parts ??
I think you have designed something that is a little outside of your
skill set and tools available.
in a craftsman's shop, he would probably make the whole table
in one piece of several laminated parts and veneer.
THEN - on a router table and table saw, cut the grooves on the ends.
this method would give you oh so much more sturdiness and be rock solid.
making individual end pieces may lead you into a barrel of frustration that
you may not be able to get out of.
option #2: would be to build the box, then use hand saws to cut out each
groove. a drill hole on each end of the groove would round out the finish cuts.

There is one other way. I have bent shapes and laminated standard 1/4" luan to make combat shields for the SCA - A renaissance group that really fights hard. Generally not open to the public. Anyway, never to this small of a radius. Pretty sure it cant be done with normal means.

I have also used bendable Luan, but not to this extent. Anyway, I have used this product and curved it on frames. What I haven't tried yet was to laminate 2 or more pieces together. Even though the lamination layers individually bend readily, when glued together in a bent shape, they should retain that shape. There would be a tension against all of the layers and that should put them in tension with eachother similar to a torsion box or an "I" beam. Each layer of I/4" could be built up to the final thickness. the more layers, the merrier. These layers could be built around a box/form and then the box removed. I'm too lazy to look it up (actually poor internet connection) and find how small the bending radius is. There was a dealer in North Houston, Tx. area. Cant remember the name but I'm sure he is still in business. He should be able to tell you all about it. Then again, it might not work, Just making an educated guess. call a dealer r manufacturer to find out.

When the form has been fully laminated. it could be covered with a finish veneer. Then the cuts could be made.

I got lucky on internet connection. Here is a link: https://www.columbiaforestproducts.c...nding-plywood/.
And here is a short note:
Specifications
2 ply construction: Rotary peeled hardwood back. Thin veneer face.
3 ply construction: Rotary peeled hardwood outer plies. Thin veneer inner ply. No face or back.
Thickness: 1/8″, 1/4″, 3/8″, 3mm, 5mm, 8mm, 16mm or contact us for other sizes.
Panel Size: 4′ x 8′ Long grain or 8′ x 4′ Cross grain.

Week #1
I bought some cheap wood today,
I tried to cut out the piece with jigsaw. It went well. The piece broke very easely tho.

I kept the inner part. I ll make one more and I make a form for plywood. Lets see how it works.

So I went to the shop today, This is all I found.

One one image there is plywood 3mm thin.
Second one is 6mm but I was told is bendable.

Any idea which one is better ?

Thet is not the bendable plywood I was referring to. Also, the stuff you are looking at probably wont bend as tightly as you want. the stuff you are looking at, when bent and glued, probably would fall apart when you cut it into strips. When bent, you would have to fill all those grooves with some kind of adhesive/filler to hold it together. Then when cut into strips and roundrd over you will see the filler. That means you will have to match the filler color to the final color that you want and then stain the exposed outer layer of plywood.
AND.................what u are looking at is not plywood, it's MDF

Don't hate me, but.....

I do not care for the grooves in this piece. they serve no function and make the concept weaker structurally and are difficult to make. A much more solid looking design in my opinion, would be to eliminate them and bend a continuous curve from thin layers that are laminated over a form.
