Whilst putting up jig #5, jig #4 fell over which knocked over all the others. I stood up in dismay, considered helicoptering jig #5 across the shed. Start again, starting with jig #5, noting they fall over best away from the props. This process consumed a whole tin of bondo, but they are all square and the edges line up nicely.
Finished tracing out hotwire templates and spray glued them to 4mm marine ply.
Poo.
Re-jigging jig #2, seemed vertical, but didn't line up with the others.
