While most animated machines we deal with every day – everything from clocks to cars to computers – are made of metal, there is an art to creating automated objects out of wood. [Dug North] is a creator of such inventions, making automata out of wooden gears, cogs, and cams.
[Dug]’s inventions are simple compared to turbine engines, but they still retain an artistry all their own. With just simple woodworking tools, he’s able to creating moving vignettes of everyday scenes, everything from a dog barking at a bird, to Santa Claus gracefully soaring over a house on Christmas Eve.
Below, you’ll find a video of [Dug]’s creation, ‘An Unwelcome Dinner Guest’ – an automated dog barking at a wooden bird. There’s also a video of him being interviewed by the awesome people at Tested last year at the World Maker Faire.

[Frank Howarth] is a very competent woodworker known on the YouTubes for his wonderful stop-motion videos of turned wood bowls. Lately, though, he’s put some effort into building furniture, this time a beautiful lawn chair made from a gigantic sequoia log.
A few years ago, [Frank] and a friend acquired a gigantic sequoia log and milled it themselves with a chainsaw. After two summers, the huge boards were finally dry enough to be used and [Frank] decided a lawn chair would be a fine project.
The sides of the chair are a single monolithic piece of wood. Of course [Frank] needed to cut the sides in half and join them together again for the decorative holes, but it’s still an impressively solid piece of woodworking. The back and seat of the chair are also made out of the same sequoia board, cut into slats held together with three very large dowel rods.
This project probably wouldn’t be possible if it weren’t for the awesome equipment and tools [Frank] has in his shop. He has a great tour of his shop available for your viewing. We should all be so lucky.
Meet [Quetico Chris]. He’s a master woodworker who likes to find his own alternatives to using power tools. Most recently, he was inspired by a fly-wheel from an old factory. He used it to build this foot powered wood lathe.
It works something like a foot powered sewing machine. There’s a lever for your foot which converts the downward force from your foot into a rotating force which drives the work piece. The mechanics of the lathe are pretty common, but we think the build techniques he uses are anything but. The video after the break shows each step [Chris] went through when crafting the human-power tool. His approach was to use wood as often as possible which includes foregoing modern fasteners for older joinery. He uses mortise and tenon, wood pinning, doweling, and a lot of puzzle-like tricks to get the job done.
We lack the skill and tools to replicate this kind of craftsmanship. We’re going to stick to letting a laser cutter form our wood connections.

A little face protection is a great idea when first testing out your homemade bow. [Austin Karls] made this recurve bow during what he calls an engineer’s Spring break.
He settled on the idea after seeing a few other projects like it on Reddit. After first drawing up a plan he headed down to the shop to cut out the wooden riser (the middle part of a bow). Unlike traditional recurve bows this is made up of three parts. Traditionally you would laminate different types of wood to achieve the flexibility and tension levels desired. But [Austin] went with a synthetic material: the tips of two skis. Each were cut to the final length and affixed to the riser with a pair of bolts.
After a few test shots he gained confidence in the design and did away with the face mask. Now if you’re in the market to take your existing bow and add some firepower to it you’ll want to look in on this shotgun enhanced compound bow.
We just got an ergonomic keyboard for the first time and absolutely love it. But the look of this keyboard hack has us second guessing ourselves. [Will Pretend] pulled off an absolutely stunning wooden retrofit for his USB keyboard. Be warned, his project log includes 175 photos, and most of them have captions.
He started off by taking apart the original USB keyboard to see what he was working with. Before digging in to the valuable wood stock he cut test pieces using some thin MDF. But once he had a clear plan to get to the end of the project it was full stem ahead.
The keys are not simple Chicklet style overlays, they have depth like you would expect to find on low-grade plastic peripherals. This was accomplished by milling each key, then sending them through the laser cutter to each the letter on top.
Take some time to make your way through the entire project (here’s a thumbnail layout if you get frustrated). Unfortunately [Will] says he doesn’t actually use the keyboard because of grains catching and the keys move around a bit too much. But it does work.
This is a cargo bicycle made almost completely out of wood. [Niels] and three of his classmates built it at Wico Campus Tio, a science and technology school in Dorpsstraat, Belgium. There’s a lot to be impressed by in this build. Sure, the guys concede that not everything is wood. They used metal screws as well as hubs, a crank shaft, and gears from a bicycle (not seen in this image). But everything else was made from Beech or Padouk wood. This includes the leaf springs that help cushion the cargo box from the bumps in the road.
The box itself acts as the handlebars. You can see the bracket which holds one end of a dowel spanning the left side of the box. This image was taken before the seat and cranks were added, but once they’re in place the front axle will turn along with the box for steering.
You can get a good look at the finished bike in the video after the break. You’ll also find a link to the Power Point slides there. Since that presentation is in Dutch we translated the text and pasted it below.

We once enlisted a contractor to cut a plywood circle for a cat condo we were building. Now we’re embarrassed that we couldn’t come up with a solution as eloquent and easy to use as this circle cutting router jig which [Grays42] built.
He’s using a small trim router for the job. The jig is made up of two thick-walled pieces of PVC pipe. We don’t think the router is attached to jig. Instead you hold it against the wooden spacer which is on the outside edge of the cut. He doesn’t mention how he made the spacers, but we’d recommend cutting a hole the size of the pipes and then ripping down the middle to remove some of the material (tape the two spacers together during fabrication to ensure proper alignment). It just takes some nuts and bolts from the hardware store to assemble everything.
[Grays42] is using this to cut rings for his telescope build. We have our eye on it for making our own wooden Bulbdial clock.
