Now the bottom is ready. Place
the bottom (with the beams turned
upwards) on a stable work table that
is approx. 1.1 m high, for instance
a pallet with 5 pallet collars. Put

protect the bottom.
(If there is still a part of the bottom
circle that you have not been able to
cut away due to the temporary board,
you can cut that part now. Saw from
below with the jigsaw.)
Rub off splinters along the jigsawed
edge with some sandpaper.
