Last night was one of those nights where I was laying in bed and I was thinking about so much stuff that it was hard to go to sleep. One of the ideas I am really excited about and have been thinking about for a few weeks now on and off is how to reduce the amount of fasteners need for the wofati roof. Current designs use two or more rebar spikes per roof log to make the roof which consumes a lot of time, energy and money. This design would remove the need for fasteners for each log.

I think that if you where to make a frame to hold the logs intoo place on the roof then you could forgo the need for individual spikes.

The first pictures show which logs would be secured with spikes. These logs would be stouter logs then the other roof logs would be. Maybe two inches larger in diameter then a normal roof log.
The three logs in the pivture would be for the structural support of the gable roof. The log on top of the top beam and the log on that is parallel to the lower beam would both be well secured. These would make a sort of frame to hold the rest of the roog logs into place. I think that the rest of the roof logs could be temporarily held into place by a rope or wire until everything is buried.

So basically what I want to know is if this will make the wofati a death trap? Will this concept work? What do you think?

Hi Sam,

I have tried to not interject too much on the "Wofati" posts, just so folks like you could "hash out" there Ideas. I have written a few times about the framework styles possibilities. There are several traditional (and mixed) modalities that could eliminate all the "iron" in these structures, as fossorial architecture has been "timber framed" (usually a post and lintel format) for millennia without any modern hardware...so we know it is very possible to do...

I won't go into to much detail of a critique, as that hasn't been requested other than to say you have a generally nice design...and...a great use of SketchUp modeling! You can eliminate the "oblique bracing" as well, if you chose replacing it with an older and more easily facilitated horizontal modality.

Regards,

j
