In your CAD program upload the picture in JPG, this is possible in most CAD programs. The picture will be used to provide the correct scale in CAD program later. 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. This Is how I transferred the shape of the lenses into cad. I made the drawings in inventor, and it worked just fine, but it is not the best 2d Cad i know off. Almost anything can be done as long as you keep basic shape of the lenses as it is. Feel free to edit mine, or use it as it is. Note: not all the pictures are form the same pair of glases.Ģ:Design: As i have said i have i suitable design, which i will be posting below. 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. Because the hinges were lacking a friction surface therefore the hinges did not stick to the wood. The exception is when I used spring hinges on the oak pair, but this was not a success. This is what I have done with almost all the pairs I have made. Or you can buy a pair of “cheap plastic sunglasses” with metal hinges, and loot the hinges. I think these would work best with my design (TH-24 5.0mm) or something similar. I think all the models in the link can be used. I found this site selling hinges suitable for wooden sunglasses. 1.5 Order/salvage hinges You will need hinges, obviously. These might be a bit expensive, but I strongly recommend using quality lenses. here is a link displaying available frogskinns (replica) lenses on ebay. I recommend polarized lenses, but it is not a must. Vibrant colors will draw attention away from the wood, and is therefore not suitable. When it comes to color i recomend using either black, brown or gray. Therefore i recomend ordering them if you are using my plans. The lenses i have used are oakley frogskins lenses. 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. This instructable is based on the use of a cnc machine. I am making this step by step guide so more people can use my design, and make cool wooden glasses. Please feel free to use my design, I only made it for fun. The same design I will be posting here, in all the formats I have available. I think I have spent more than 30 hours developing the final usable design. Naturally that is also the reason they look similar. The shape of the shades is similar to the oakley frogskins, infact it uses the same lenses. I have developed a design witch looks and works very well. But now as I am 18 years old I know a lot more :P, have more experience, but my English is still rusty. 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. My research in the project started basically from scratch. But about half a year ago I finally succeeded. My first attempt at making wooden sunglasses was 4 years ago, but that attempt did not succeed very well.
