I thougt about using because it was recommended as a good material to bould in. Uses bamboo plugs because it get nice and strong joining, and because it is a prosedure used in Harold.A.Underhills bok.Good luck for this build.
Why boxwood and bamboo ?
Hallo and welcome to Norway on board of our forum.
Interesting, that you started your built with projects in the project. (anchors and tree nails)
Which documents or plans are you using for your built in scale 1:30 ? - BTW: an interesting scale!
