My J/24 is sitting on the trailer, the weather is decently warm, and I have a few weeks off of school for the holidays. I am looking to fair the keel. How do I make a set of templates? I know that the minimum dimensions are in the Class Rules, but I don't know what to do with them. What should I make the templates from? Should I make them in halves? How do I measure to see if the keel is centered in the boat? Does anyone have a photo of their templates? I'm not trying to take anybody's design, I just want to see what I am about to try to make. Any info anyone has would be great.
