Hello,
I have a rather small project (kneeling chair), which I designed for myself (PC work & lower back pain). I would like to do it entirely by hand, as it would be a good practice for me.
I would like to ask how did they thickness boards before machines were used? Did they marked and thicknesses each individual board to become coplanar and parallel and then they found the thinniest board and thicknessed all remaining boards to this minimum thickness? For a machine it is easy to run all the boards again through a thicknesser and set it to the lowest thickness that was measured from all the boards, but if I have to layout the perimeter around each board according to the thinniest board found and plane every board to that thickness, then it seems to be a lot of work.
And before making all the boards coplanar and parallel, I cannot estimate the greatest common thickness, that will yield coplanar results from all the boards.
Thank you.
