Most glasses and sunglasses on the market make use of metal or plastic frames. It’s relatively easy to create all manner of interesting frame geometries, tolerances can be easily controlled for fitting optical elements, and they’re robust materials that can withstand daily use. Wood falls short on all of these measures, but that doesn’t mean you can’t use it to make a beautiful pair of glasses.
ZYLO is a company making wooden eyewear, and this video from [Paide] shows the build process in detail. Modern tools are used to make things as efficient as possible. Parts are lasercut and engraved to form the main part of the frames as well as the temples (the arms that sit over the ears to hold them on your face). A special jig is used to impart a curve on the laminated wood parts before further assembly is undertaken. Metal pre-fabricated hinges and screws are used to bolt everything together like most other modern sunglasses, but there’s significant hand finishing involved, including delicate inlays and highlighting logo features.
In contrast, Manuel Arroyave works very differently in the creation of his Cedoro glasses. Sheets are first laminated together, before the shape is roughed out by a special horizontal axis milling setup. Even small details like the hinges are delicately hand-crafted out of wood and fitted with tiny wooden dowels.
It goes to show that there’s always more than one way to get a job done. We’re tempted to break out the laser cutter and get started on some custom shades ourselves. Perhaps though, you’re too tired to put your sunglasses on by yourself? Nevermind, there’s a solution for that, too. Video after the break.

Dowels are a useful woodworking technology making it easy to connect several pieces of timber, particularly with the aid of adhesive. However, depending on where you live, it can be difficult to come by a wide variety of stock. This is particularly important if you’re concerned about appearances – cheap pine dowels could spoil the look of a delicately finished hardwood piece, for example.
Thankfully, it’s easy to make your own dowels at home. [Pask Makes] has used a simple dowel plate before, but this time, decided to build the deluxe version. A thick steel plate is drilled with a series of holes, and then mounted to a wooden block. Square stock can then be forced through the holes to produce the dowels.
[Pask] notes that there are several methods to use the dowel plate. Hammering the wood stock through the holes works best for hardwoods, while fitting the square stock into the chuck of a power drill and forcing it through while spinning gives a better finish on softer woods. There are also useful tips on how best to produce dowels, with notes on strength and grain orientation.
It’s a useful tool to have in your workshop, and means you can turn just about any wood into dowels for your woodworking projects. If you’re fresh to the world of wood, worry not – we’ve got the primer to get you started. Video after the break.

The 1960s were a heady time, with both society and the language of design undergoing rapid changes over a short period. Back in 1968, Henrik Thor-Larsen exhibited his Ovalia egg chair for the first time, at the Scandinavian Furniture Fair. With original examples now antiques, and with even replicas being prohibitively expensive, it might just be worth considering building your own if you need to have one. Thankfully, [Talon Pascal] leads the way.
It’s a replica that’s built with accessible DIY tools and techniques. The frame is built up from plywood parts, cut out with a jigsaw. These are then assembled with glue and screws, forming two halves of the full-sized egg assembly. The exterior is then covered with thin strips of wood, as opposed to the fiberglass construction of the original. This is smoothed out with a judicious application of wood putty and plenty of sanding. The interior is then lined with foam before the chair is upholstered with red fabric. We’re not sure exactly how the trim ring is fitted, but it gives the chair a nice clean finished edge and rounds out the project nicely. There are even embedded speakers so you can chill out with some tunes in your ovaloid sanctuary.
It just goes to show that there’s value in the old adage – if you can’t buy it, build it! Perhaps, however, you’re outfitting the office – in which case, would something from the Porsche range suffice?
Hackaday is primarily a place for electronics hackers, but that’s not to say that we don’t see a fair number of projects where woodworking plays a key role. Magic mirror builds come to mind, as do restorations of antique radios, arcade machines built into coffee tables, and small cases for all manner of electronic and mechanical gadgets. In some of these projects, the woodworking really shines and makes the finished project pop. In others — well, let’s just say that some woodwork looks good from far, but is far from good.
