Hi Tim
As per your other thread it sounds as though you have decided not to follow the designers instructions!
Fair enough that you have decided to add some timber frames but if these are not part of the design/plans how did you obtain the shapes?
How big are the gaps and are they symmetrical to both sides of the hull? If it was me I'd make some templates out of card first and once you've got a good fit then make them in timber.
By the way my Permagrit files arrived and I've given them a go. They certainly are good and make life much easier. Much better than wrapping sandpaper around bits of wood or using normal files.
Chris
