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).

Finished table for now.

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.

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.
