Roundhouse master Tony Wrench takes us into the exact details for building a reciprocal roof frame, from organizing and design to selecting and laying out your rafters, to the actual framing.

Paul bough the Fresnel lens, but if you look on Craigslist you can find people giving away Projection TVs with these lenses.

Continued from Part 2 (Sort of) where we are trying to melt glass with the sun but we got hungry. A Fresnel lens from an old TV is more than enough to melt butter on toast in about two seconds, but will it be enough to melt glass? Paul wants to recycle glass on site to make cool stuff instead of driving it to the recycler two counties over, but I think we need a bigger lens. Fortunately Josiah has some more ideas for making a solar glass furnace. This is the kind of stuff we do at the Permies.com Appropriate Technology Course (now the Permaculture Technology Jamboree) at Paul Wheaton Labs in beautiful Montana. Stay tuned as we share more clips from previous years including the rocket heater we were able to cast a glass pendant in. Or even better, join us in Montana this summer.

The purposes of the PTJ are:
1) Participants gain hands-on practice in a fully outfitted homestead fabrication and repair shop with tools from welders to sawmills to excavators under the instruction of experienced teachers--think of it as a shop class for homesteaders.
2) The PTJ is a serious research & development forum for DIY low-impact technologies such as Rocket Mass Heaters, Thermal and Photovoltaic Solar, and Local Natural Materials Building. Participants help us push the envelope on what is possible with appropriate technology.

Continued from Part 3. There's not much difference between these two Rocket Heater J Tubes but that little bit makes a big difference in the performance of the water heater we were building at the Permies.com Appropriate Technology Course (now the Permaculture Technology Jamboree) in the summer of 2019 at Paul Wheaton Labs in beautiful Montana. Stay tuned as we share more clips from previous years including the fantastic shower heater we built from one of these. Or even better, join us in Montana this summer.

THIS IS THE EBOOK VERSION. THE PRINT VERSION IS  here

Tony Wrench, the Roundhouse Master himself, brings us an in-depth look at building the low impact roundhouse from local natural materials. He covers it all from planning and hosting the build, to materials, to cutting and framing the walls and reciprocal roof, and finally turfing the living roof.

"Some people, as soon as they see or hear of roundhouses, want one. It is usually love at first sight. If you are one of those people, this is to show you in as simple terms as possible how to build a round den, a shelter or a roundhouse in the style that I have worked out. It is a certain kind of design, adapted over about fifteen years, which incorporates bits of Celtic, bits of First American, and ideas taken from permaculture and the natural building movement. I trust you will take this book as a guide, and end up building something that is definitely your style, because we are all different, and are building in different locations with varying materials.

In my previous book ' Building a Low Impact Roundhouse' I talk about how Faith and I came to various decisions in building the house we still live in. It is more of a story, although some brave souls have built houses using it as a guide - in the US, Wales, England, Scotland, Ireland, France, Russia, Alaska, Canada.... However, when I built our roundhouse I didn't actually know how to do it. I was making it up as I went along. I have had more practice now so this book is more of a 'How To’, although there is always a bit of a risk in advising anyone how to do anything.

Here we are working on the cob finish details of a passively heated and cooled experimental underground natural home at the Permies.com Appropriate Technology Course (now the Permaculture Technology Jamboree) every summer at Paul Wheaton Labs in beautiful Montana. Stay tuned as we share more clips from previous years to give you an idea of what is coming up.
