Hi clash,
roundpole framing can be as simple or complex as you like. The simple way with a pitched roof and a central beam which is how many of the buildings on the site are built, is to put the main beam in position, then layout the rafters on the beam/wall then notch the ends of the rafters slightly to sit on the beam so they feel snug do the same with the other end if it sits on wood, if it's on cob just pack it in place with some cob. Sometimes we put a peg through the timber into the cob to hold it in place or stop it rising. The notch is scribed with a log scribe, or by eye which seems to work well enough after a bit of practice.
The poles are then either spiked, nailed, or coach screwd to the beam.
It takes a bit of practice to select the right poles for the right place and cutting the notches neatly. We use an 'arbortec woodcarver' on a grinder, you can also use decent size gouge chisels, (expensive) or make your own. Check out 'Creative Country Construction' a handy book about log building you can probably get it on Amazon, it's not that old. This shows you a variety of techniques which are suitable.
On our course we will cover all this stuff, and the selection of poles and making a pegged cruck frame.....etc
Anyway hope this helps a bit
Need more info just ask

cheers alan! have checked out amazon and they have the book you mention. Thanks for the info about how you guys do them as well. sounds easy enough with a bit of practice. we are planning on trying out our first cob structure next summer... (we've been busy making test bricks and gettin' a feel for the mix) The building will be a dual chamber compost toilet (similiar to what you've got in the gallery on the site) plus an indoor woodfired bath, so, were thinking of doing a shed roof at a very slight angle or perhaps just flat. Got any contacts were one can buy EPDM in one large swath?
Is it the 7 day cob course that you teach the roundpole roof framing? Will you be doing any courses or workshops in Scotland in the future?? |

Hi Clash,
With regards to the EPDM question I can't remember where Alan sourced it and he is away at present but I'll get him to post the details on the forum when he gets back at the end of the month.
The 7 day course mainly focuses on cob with some wood work. The 5 day course taking place beginning of July is for the roundpole timber frame.
No courses up your way at present. Sorry.
All the best with your building project.
