Joists or Jowl? 20th April 2019

My dream brings tears to my eyes. I need to make a decision about a beautiful tree.

This week I have been overseeing the milling of a large oak tree and supervising the making of clay lump blocks. I pinch myself, and it hurts. Please don't get me wrong, I love what I do, and feel very blessed to be project managing the reinstatement of a 1580 Timber Frame. It's 'like for like' using locally sourced trees, but with it comes layers of responsibilities that pull at my shoulders … I want to do right by these trees …

On Monday I went to measure the Jowl Tree. This, is the name I had given a 6M long oak felled last year to let more light (and subsequently more flora and fauna) into local woodland. Jowl Tree has a huge buttress, just perfect for turning upside down and using as key support in the timber frame.

When I last visited this tree it spoke to me of becoming four jowl posts. A person with cleaving experience could open this tree lengthways and make full use of its natural curves. Each half could be halved lengthways.  We have in the past used a Lucas Mill to convert tree into jowl and because of the nature of the straight cut of the machine, whilst it is do-able, it is also hugely wasteful of wood. For this reason, I am reluctant to mill this tree.

Dare I dream of this huge Jowl Tree being hand converted? Dare I?

My other dilemma is this:- for the next stage of the Long House project I need 32 ceiling joists, much smaller pieces than the mighty jowl. I was loathed to get the jowl tree milled into joists, so on Monday I had come to make my peace with the tree and to explain to it what was to happen. I was sad, but there didn’t appear to be any other choice, or was there?

I found the woodsman and his apprentice splitting firewood. Their main trade is firewood, and in my heart of hearts I am pleased the Jowl Tree was to become a building, even if that meant as joists and not jowl.

Long story. Short. Unbeknown to me there is a second oak, a bigger straighter tree that would make perfect joists and plenty of them.

BIG BIG thank-yous to Graham and The Universe for listening. And maybe, just maybe the Jowl Tree will one day become four jowls?
