Our freshly raised black walnut bent

In this post, I’m going to rewind back to June of this year when Wabi-sabi hoisted its first timber frame bent to vertical. (A “bent” is a cross-sectional assembly of posts and beams, part of the framing of a timber frame structure.) This particular bent was composed of two roundwood oak posts, and a hewn black walnut beam, with a span of around 18 feet. No small feat!

Wabi-sabi Kitchen Timber Frame Bent Raising Report

By Wabi-sabi Kitchen, Timber Framing

Wow, I am way behind in reporting news on Wabi-sabi’s kitchen construction. Things are happening, I assure you. Even though it might not look like it when you walk by our site every day. (Timber framing ain’t a quick job…)

The biggest thing to have happened in some time just took place last week when we raised our biggest bent yet – a lunker composed of three posts, and one long beam with a scarf joint, the same assembly we worked on during our timber frame workshop in May. The thing must have weighed nearly 2000 pounds, and we used a super slick system of pulleys and human power to raise the beast.

Anyway, you’ll have to wait for my own personal account of the event (I swear I’ll post some video soon!), but thankfullly Alline of Dancing Rabbit has posted her own eyewitness account of the event with plenty of photos.

It was an intensely exciting and rewarding day, I’ll say. More soon! I mean it, Mom and Dad (and all you other readers that don’t pester me as much).

 

My Cob House in Popular Mechanics Top 10 “Backyard Genius 2011”

By Media

Strangely enough, my house has been featured in another magazine — this one a rather strange one. Popular Mechanics recently interviewed me for their so-called “Backyard Genius” Top Ten. Alongside all the praise for gloss and high tech gadgets in the mag is a little piece about my house, built out of mud.

I like that its inclusion is kinda subversive, in a way. Ha!

A small blurb can be found in the latest issue (September 2011), and in their online feature.

Check it out.

Good News Regarding Humidity Levels in Cob House

By Cob Building

I finally have some promising moisture news to report. After removing the original earthen floor in Gobcobatron, we put down a 6 mil poly liner, and our 1.5″ of rigid foam insulation.

The new floor is not yet fully in, but our hygrometer is reading lower than ever humidity levels! Previously, it was rare for the humidity to dip lower than 75-80% (yikes, yes). 65% was welcome when there was a strong breeze through the house.

Well, now that same hygrometer is reading more around 50% humidity, a much more acceptable level of moisture. Wow! I’m trying to not get too-too excited yet, because of course the floor is not yet complete, but I do believe this is an excellent sign for positive change. It suggests that moisture was indeed rising up through the gravel in the floor.

More on that later!

Earthen Floor Demolition Video

By Video, Earthen Floor, Resources

Here’s yet another video of me destroying something in or around my cob house. This time, I take a pickaxe to the earthen floor inside Gobcobatron. Breaking it up was fairly tough work, but worse is trying to cleanly scoop up the material and carry it out of the house in buckets. Yuck. Well, I’m glad that’s over with, at least! It took a bit more than a day to complete, not without the help of a few hands throughout the process.

The Decision To Use Pink Rigid Foam Insulation

By Moisture, Earthen Floor

I must confess: I’ve decided to use some pink foam insulation. I hate the stuff: it’s plastic, it’s a product of a polluting industry, it’s gross to work with, it’s non-biodegradable. And it has no redeeming ecological value. (Am I being harsh?)

It’s become clear that in my particular floor, at this particular time, and with my particular lack of willingness to experiment at this moment, it’s the “right choice”. Just over a week ago, April and I decided to go ahead and replace the entire earthen floor in the house, in hopes of continuing to alleviate the high humidity in Gobcobatron.
