Logosol M7 - Build a Bench

Design: Mattias Byström
It only takes an hour or two from log to
completed bench. Use a chainsaw, folding
rule, set square, hammer, and nails – and
do not be unecessarily precise, you will get
a good result anyway!
Boards:
Diagonally sawn 2”x7” (51x178 mm):
two 185 cm (72”), two 35 cm (14”).
1 1/4”x7” (32x178mm):
one 140 cm (55”), four 35 cm (14”).
Building instructions:
Draw a curve on the 140 cm (55”) long board
(e.g. by attaching a pencil to a 150 cm (59”)
long string and fastening the other end of the
string 142 cm (56”) from the center of the
board). Let the curve barely cover half the board
width. Saw along the drawn line with a saw.
Nail two of the legs (A) to the curved board.
Make sure that the curved board does not
protrude from the outer side of the leg board.
Mark the middle of the short, diagonally cut
boards (B) and nail them to the legs, centered on
the end of the curved board. Let the diagonally
sawn piece stick up 3-4 mm above the leg board
and the curved board.
Attach the two other legs with nails (C).
Cut off the leg boards with the chainsaw (C) so
that they are in line (D) with the upper corners
of the short diagonally cut boards (B) and the
lower corners of the legs.
Place the long, diagonally cut boards (E) on
the construction, and nail them to the short,
diagonally cut boards with a space of 1 cm
between them.
Finally, you carve off the rough edges with a
sharp knife.

Design: Mattias Byström
To produce the two diagonally sawn boards,
make a 7” block that is 221 cm (87 inches) long.
Make a diagonal cut by not letting the cradle
foot on the short arm reach the notch in the
screw plate, but letting it be positioned next to
it. Support the guide rail by placing sticks under
it, in order to prevent the guide rail from moving
while you are sawing. Make sure the block is
securely fastened.
