4) Use a finger to align loose fibres on
the edges of the V-groove cuts so they
don't get caught when folding the panel.
5) Use 120grit (or similar) sand paper to
gently tidy the cut edges of all port pieces
so they will fit nicely in to the rebate slots.
It is recommended to do this over a dust-
bin or using a vacuum cleaner to collect
dust as it falls.
A knife blade can may help to remove
stubborn dirt from the narrow port rebates
and other small areas. The panel should
be perfectly clean so nothing will obstruct
the assembly. Do not use a knife in the V-
grooves.
