Making Bellows

making bellows

“This is hopefully the start of a set of documents that will help in the construction of a portable, authentic forge and bronze casting set up. I am starting with the bellows as I can use them at home to help get the fire going in the winter months.”

“I have repaired a number of sets of bellows, but this is the first set I have actually made myself from scratch. They appear to work well – good flow rate, nice range of movement, practically no air loss. If you follow any of the instructions below and it doesn’t work properly – well then you are just doing it wrong.”

Open Source Water Boiler

“Coffee makers and water boilers are relatively simple machines, yet their workings are typically inaccessible to the user. Repair or even recycling becomes impossible: once the product ceases to function, it is rendered disposable. The OS Boiler explores an alternative approach to the design and production of these ubiquitous appliances. Based on the OS design principles, the WaterBoiler’s (completely disassembleable) design and transparent construction invites users to adapt, repair, and combine with existing OpenStructures components.”

“The limited complexity of the Boiler allows new partnerships to emerge that can adapt to the scale of production: a single unit designed as a DIY kit to one-thousand units produced in a collaboration of international suppliers and local manufacturers. Consistent application of simple and straightforward principles in design and production leads to an object that can evolve and adapt over time.”

Robin Wood, Bowlturner

robin wood bowlturner“The bowls created by Robin Wood’s reconstructed lathe have an unique finish, which is only found in bowls cut with a traditional pole lathe. The sharp tools leave a distinctive mark much like the lines found on thrown earthen ware or glass. The clean cut with the sharpened tools means that the objects are practical for everyday use. They can be washed with warm soapy water and will not fuzz up, unlike a bowl cut
on a machine lathe and later sanded smooth. Robin’s bowls and plates only improve with use and ware.”

“Of course making wooden table ware for a living means making thousands of items every year, which seems rather a tall order when you consider the technology being used, but Rob insists that his pole lathe can turn out wooden ware as quickly as the mechanised equivalent. This theory has been put to the test and proven correct. As Robin explains in the
film, when he’s powered up, so is his lathe and he can get results quickly. When he stops the lathe turning he can adjust the wood instantaneously, whereas when you power down a mechanical lathe you have to wait for the machine to slow down and stop turning in it’s own time.”

Any fool can make something more complex but it takes real genius to make things simple again“. A new video by Artisan Media. Robin Wood’s blog.

Building Plans for Dutch Industrial Windmills (1850)

This collection of 21 building plans for 5 different types of Dutch industrial windmills was published in 1850. There is a saw mill, an oats mill, a flour mill, and two pumping mills. The book contains no text, only illustrations.

Make Your Own Treadle Lathe

make your own treadle latheIn the last twenty years or so since I built this foot-powered treadle lathe, I have received many requests for drawings or plans.

The lathe has been used as part of our traditional woodworking demonstrations and it never fails to draw a crowd. Of course, the reason the lathe exists is because I felt a need for it as a tool.

Some of the main considerations when designing the lathe were:

  • Human powered — our solar energy system was pretty small at the time
  • Size — it had to be less than 42″ tall to fit into our old truck
  • Compact — since it would sit in our small shop all the time, a small footprint was essential
  • Portable — as in not too cumbersome or heavy
  • Functional — it had to perform the basic duties of a light-duty lathe
  • Adaptable — I had in mind several untraditional uses for the tool, like sanding”

Climbing Tall Stacks with the Aid of Kites

“Having occasion to make emergency repairs to the large 170-ft. chimney of the Consumers’ Ice Company, Chicago, and finding that the cost of erecting a scaffold ran up into hundreds of dollars and would take too much time, I decided to use one of my cellular kites for the purpose of hoisting and attaching a suitable block and tackle.”
