Made of round bar of pine (the helix) and three pieces of edge-glued panel (pine) glued together (the base). Waxed.
Tools used:
Triple helix: power drill and a stand, chisel, knive, sandpaper – and some maths to calculate the optimal values for the drill bit diameter and the hole positions.
Base: hole cutter to cut the basic round disks, then knive to carve the final round shape, and some sandpaper for final touch.
