I've made a few over the years. I can say you are very ambitios to try it on your "good" wood first. I learned using scrap wood.

Well, its not new, that's for sure. It's at least 40 years old I think. My great uncle bought it years ago from a local fisherman who was building a new boat with it and had it left over. Apparently he got a huge trailer load behind his tractor for $30. Today if it was finished it would be worth ALOT more than that.
Also, I thought if I did a decent job on it that I might as well use decent wood so if it turns out, all that time isn't wasted. We shall see lol.
