Stephen has taken it off the site as I intend to start from scratch and starting to order necessary item for the build. Balsa never used it seems to burst with me. I think you have to cut it with the grain. Now I believe there is 3 types of balsa soft, medium and hard. which type would be best for sanding and shaping the bow and stern. I would have like to use planks all the way from bow to stern but using a simple mock up the bend was too much breaking the planking, even soaking and heating planks. It would be balsa blocks to be used. Huh.. nearest model shop is 60 miles away and not all stock wood. Lastly what would be the best fiberglass matting to cover the hull. A type that is not too hard to work with.
