Technology for Luddites
“Hi everybody my name is Chris. I choose my woodworking projects based on whatever happens to inspire me”.
In this video, Chris builds a foot powered treadle lathe. Great project, great video.

“Lumber is usually dried to a specific moisture content prior to further manufacturing or use. While lumber can be air-dried, the humidity in most localities prevents the lumber from reaching the moisture content required for the stability needed for interior use. The kiln discussed is designed to be inexpensive to construct and be simple to operate.”
“The solar kiln described was designed, constructed, and tested at Virginia Tech. This design is based on 25 years of research and development on the solar drying of lumber in the United States and foreign countries. Drawings for two versions of this kiln are available; one for 800-1,000 bd ft and the other for 1,500-2,000 board feet of lumber. Both kilns will dry a load of lumber in approximately one month of moderately sunny weather at its location in Blacksburg, VA.”
“Drying lumber can be a complex process where accelerating drying without having quality loss often requires extensive knowledge and experience. The design of the Virginia Tech solar kiln is such that extensive knowledge, experience and control are not required. The size of the collector keeps the kiln from over-heating and causing checking and splitting of the wood. The kiln is simple to construct and utilizes a passive solar collector, four insulated walls and an insulated floor. The roof is made of clear, greenhouse rated, corrugated polyethylene.”
“They are hard to build with, they require regular maintenance, they are expensive and they flex a lot. However, if you want a traditional looking wheel, avoiding metal altogether is a marvellous move, something that we’re lucky to still be able to do today.”
Cerchio Ghisallo has been producing wooden rims since 1946, and in this video father and son show how they do it. Inside Cerchio Ghisallo part 1, part 2, part 3.

“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.

“Resawing is the technique of ripping boards across their width to make thinner boards. It’s useful for making things like drawer sides, box dividers, custom veneers, or slices for bent wood laminations. This is the alternative to planing thicker stock down, which wastes a lot of wood.” Read more.
In 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:
