Make something big
I made a wooden low table, for an illustrator who works with us
as an intern of our fab lab and have just moved to a place close
to the lab. The design requirements is to use for dining and
drawing, to put on Tatami (straw-mat) floor, and to be
easy to carry around (totable).

Because our fab lab is settled in the shared studio, which has
architectural firms and a carpentry workshop, etc., portable
work tables and lumber remnants are stored.

Storage area in our shared studio Coop Kitakagaya.
Therefore, I decided to make a table using the simple structure
of the work table as a reference and the lumber remnants (24 mm
plywood sheet 600 mm x 1200 mm) as a material.

The process of milling wood.
I drew a plan with a vector graphics editor, and exported as a
DXF file. Then I set some parameter and made NC tool paths with
TypeEdit software. I cut the plywood by using CNC router
(Woodpecker, made in China) with 0.125"/3.175mm 2 flutes spiral
end mill at the cutting depth of 1 mm at a time. It took me
approx. 30 min to finish cutting out each part.

Result of cutout.
These three parts were sanded with abrasive paper (#60) and
assembled into the finished table for now. Next, I would like to
try to use flexible structure.
