1. The sides and centre supports were cut
from the 900 x 900mm piece of marine plywood. The curves were drawn using the lid from a bbq. Any large circular item can serve as a template.
2. After cutting out the sides the remaining piece was used to cut the centre section. There wasn’t enough to cut a complete section, so pieces were cut to make a whole section and these were joined together using a biscuit joiner and exterior wood glue.
