Title: Options utilize big trunk
Post by: esarratt on April 16, 2020, 12:26:00 PM
I am building an 8x10 timber frame shed.  This is my first little project before I start building my house.

The trunk of the oak tree I plan cut is about 3' diameter at the base (see pics).

I can easily imagine how to use wood which is 14" or smaller in diameter, but I am lost as to how to COMPLETELY use such a large trunk.

My thinking is to box heart the center and cut posts/beams out of the rest.

OR

Is a trunk this nice--it is quite straight, best for shingles?

OR

???

I am just looking for ideas.

Thanks!

I don't know anything about shingles.  That looks like a red oak.  I'm imagining a shed built out of just one tree.  A wiser man would design a shed and mill the tree to meet parts of the cut list.  I would mill the tree and then figure out how much shed I could build with the results.  A lot of the sheds and barns around here are "balloon frame" where the studs are 4 feet apart and the oak siding is structural.  That cut list would be 2x4's for the walls and rafters, 1" boards for the siding, flooring, and perlins.  Estimating the board feet in the tree is pretty easy, I have no idea about how to estimate shingles.

I would be planning how to move it before what I would cut it into. Putting 30 inches for mid point diameter of 8 foot log in the weight calculator it shows 2500 # and on a sidehill besides. And that's just the first log. At least it is accessible by road and you could get some kind of machinery to it. You tuber lets dig 18 just weighed a similar log and it was 4300# and he had an excavator and a front end loader to move the logs and control the stump when cut off.

Personally I would look to get my siding out of the jacket boards and as grade dropped get my timbers from the lower grade, interior wood, until such time they became compromised.  Of course the log will let you know what options you have as you begin to open it up.
