I’ve done some “easy” stock preparation with the seating slats. I take my time and use it for planing practice.
I really have some problems with planing the edges to a 90° angle. Somehow I seem to prefer the edge closer to me, allthough I seem to get a full shaving. I am trying to compensate and fine tune the edge with a block plane, which is easier to manipulate.
Well, I am just at the beginning of my “apprenticeship”, so I will have lots to learn and practice.
With the bad weather, it is not that much fun on the balcony though, I hope it is getting better tomorrow.
I am also in the middle of drawing the templates for all the pieces with a free CAD-program. I actually wanted to include them here, once I am finished.
There is one problem though, which they did not get by using a band saw. It is the bevel of the upper and lower rear crosspieces. The devil is one little detail and difference to using Hand tools. They just tell us to set the table of the band saw to a certain angle. If you are sawing those pieces, the lower part of the boards just follow the upper template correctly.
If you do those curves and bevels by hand, you kind off need templates for the upper and the lower side of that board. The small sketches in the original plans/ PDF-file are only for the upper side of those boards.
The templates of the lower side for these boards depend on the thickness of the used material.
All the beveled edges in these templates shift by
y = x * tan(α)
in radial direction perpendicular to the curves.
For the upper crosspiece with a bevel of 30° and a thickness of 27mm that results to 15,6mm, which is actually quite a lot. Even with the suggested thickness of 3/4″ that would be 11mm ~ 7/16″.
So, it does not make sense to release a generic and complete set of templates, if everyone uses a different material.
The former “easy” setup of the chair just became a little bit more tricky.
