Your aluminum angel keel clamp is a great idea that I should have thought of when an articulating clamp is unnecessary. It looks like one side screwed to the board and the other is possibly just machine screws and nuts to get the vise action. It that close? The model was well done start to finish and its final home port caste. PT-2My wife being Scandinavian, I decided to do a Viking Longship as my next project. Problems have already arisen. First, the keel was warped so after glueing in the ribs, I added some stiffeners between each of them. Then I put in some reverse bend and left it in the jig for a day. Thankfully most of the bend has been removed. I think the planking will finish the straightening job. Second, the planking has a lot of laser burn dust that has turned the wood a nasty grayish color what I can't remove, Sanding only spreads the dust and makes it worse so I'm hoping Tung oil will tone it down a but, at least it looks a little better after running a test on some scrap pieces of the ply. The garboard strake has been installed on both sides and so far the build is pretty straight forward.
