Gregg Spies Posted April 2, 2010 Report Share Posted April 2, 2010 I have to laminate three pieces if timber together for an unstayed mast, and the plans are not clear as to which way the glue lines should run...ie fore and aft, or side to side. I am thinking fore and aft, as it would be stronger in that plane and allow for mast flex to the sides. Am i correct? It is only a shortish mast at 4.6m long for a Jimmy Skiff and has a leg'o'mutton sail. Thanks Quote Link to comment Share on other sites More sharing options...
Frank Hagan Posted April 2, 2010 Report Share Posted April 2, 2010 Fore and aft would be my guess, for the reason you cited, especially with plain sawn wood. I suspect that the loads are not that high on the mast, and it probably won't matter that much. Quote Link to comment Share on other sites More sharing options...
Al Stead Posted April 3, 2010 Report Share Posted April 3, 2010 I lamenated up the mast for my weekender this afternoon. I made it as a four sided box. I oriented the glue lines so that they fell on the sides like you. I also glued in some blocks to fill the inside space at critical places on the mast such as where the gooseneck is mounted. The main reason I oriented the lines on the side is I didn't want to drill holes through the glue line to shove bolts through. I don't know if it matters that much, but it seemed the thing to do.
