Hi I am form Norway.
My first attempt at making wooden sunglasses was 4 years ago, but that attempt did not succeed very well. But about half a year ago I finally succeeded. My research in the project started basically from scratch. At the beginning I had only a very basic homebuilt cnc(I still use) it and no clue about how to program it, neither how to draw in a CAM/CAD software. But now as I am 18 years old I know a lot more :P, have more experience, but my English is still rusty.
I have developed a design witch looks and works very well. The shape of the shades is similar to the oakley frogskins , infact it uses the same lenses. Naturally that is also the reason they look similar.
I think I have spent more than 30 hours developing the final usable design. The same design I will be posting here, in all the formats I have available. Please feel free to use my design, I only made it for fun. I am making this step by step guide so more people can use my design, and make cool wooden glasses.
This instructable is based on the use of a cnc machine. It is also possible to make the shapes with a laser cutter, or by hand, but then you must change the design a litte bit.
1: Order leneses
. i recomend using high end lenses. The lenses i have used are oakley frogskins lenses. Therefore i recomend ordering them if you are using my plans. When it comes to color i recomend using either black, brown or gray. Vibrant colors will draw attention away from the wood, and is therefore not suitable. I recommend polarized lenses, but it is not a must.
here is a link displaying available frogskinns (replica) lenses on ebay.
These might be a bit expensive, but I strongly recommend using quality lenses.
1.5 Order/salvage hinges
You will need hinges, obviously. I found this site selling hinges suitable for wooden sunglasses. I think all the models in the link can be used. I think these would work best with my design (TH-24 5.0mm) or something similar.
Or you can buy a pair of “cheap plastic sunglasses” with metal hinges, and loot the hinges. This is what I have done with almost all the pairs I have made. The exception is when I used spring hinges on the oak pair, but this was not a success. Because the hinges were lacking a friction surface therefore the hinges did not stick to the wood.
The metal hinges salvaged from “cheap sunglasses” do have “hooks” witch makes them suitable for inserting in wood, but they are quite hard to mount correctly. This I will be covering later.
note: not all the pictures are form the same pair of glases.
As i have said i have i suitable design, which i will be posting below. Feel free to edit mine, or use it as it is. Almost anything can be done as long as you keep basic shape of the lenses as it is. The file is made in autodesk inventor. I made the drawings in inventor, and it worked just fine, but it is not the best 2d Cad i know off.
From lens to CAD.
This Is how I transferred the shape of the lenses into cad.. Start by taking your lens, press it down on a flat piece of paper, then trace around it with small pen/pencil.(see picture) Place a ruler on the paper, then take a picture. The picture will be used to provide the correct scale in CAD program later. In your CAD program upload the picture in JPG, this is possible in most CAD programs. When you have your picture in cad, make a reference line the same length as your ruler. Then scale the picture so the line you drew is the same length as the ruler. Now you have 1:1 scale. Now all that is left is to trace over the picture you uploaded.
NOTE: take the picture exactly above the lens, and maybe you need to crop the picture in paint before you import it to you CAD software.
Other alternative, tape your lens onto the computer screen and draws around it. I did this the first time, but it is not the best solution!
Once you have your outline of the lens in CAD you can design whatever you want. The simplest approach is to draw one side of the frame, then use MIRROR command to make the other side. Happy designing.
the files are in: pdf,dxf and inventor part.
Update: I have now uploaded the files in dxf+dwg 2007 version, this files will work for most of you. All the parts are in a single document, including a “laser cut” piece. All the pieces are in the first pdf file.
The other dxf and inventor files are in 2014 format.
You will also need a cam file,but i see no point in posting my files here. Because i dont think the file i have made wil fitt your cnc or laser cutter. The simpelest cam software i know of is cambam http://www.cambam.info/ they have a free trail.
