Just a few photographs of next years lumber to be cut.
The logs on the left were delivered yesterday (30-12-2009) and cut down the day before. They measure 2’ diameter (smallest) by 10’ long.
The same logs, this time showing the M7 saw mill. I estimate that I will get about 750bf of lumber from this small stack. Most of this will be milled to 12/4 or 16/4 – I already have a large quantity of 8/4 & 4/4.
As the tree was cut down mid winter, it has not been taking any moisture for about 4 months and has been frozen to -30°C for quite a few weeks, the MC of the wood is only about 40 – 50%. Once cut, this will all be air dried outside for at least 2 years, before moving inside for another year or so, where it will easily become 8% MC in this time. It is not a fast process, but it will be well worth the wait. I do expect to get some splitting of the boards, but they will be painted when the freezing weather stops and before the warm sun gets on the ends.
I have not counted the growth rings yet, but I estimate that the tree is over 200 years old and quite rare to find a birch of this size and in such good condition at the base (no rot).
I’ll post some more on the cutting of the logs in the spring time when it is a little warmer and dryer.
