Bridle board and attaching flying lines
This is not 'rocket' science!
As a rough guide, when I make a primary with a loop at 1 end and
the other end bare, I allow 4-5cms after the mark at the bare end (to be
tied to the kite) and 1cm for the knot plus 4-5 cms for the loop at the
other end. I say 4-5 cms as it depends how nimble your fingers are at
tying
the loops and knots. So as a guide, allow 10cms extra for every primary.
For the secondaries, which have a loop at each end, I allow 1cm for each
knot plus 4-5cms for each loop, giving approx. 10cm extra for each secondary
as well.
