Re: Bob Perry's take on Wolfenzee's dream boat
On the subject of wood sticks, I have a question for the woodies. As spruce is more rot prone than fir,and the hollow wood spar invites rot to a high degree, perhaps we should consider how they prevented rot in old sailing ships, by putting in salt shelves between the frames and dumping salt in, to sit on the shelves and slowly pickle into the wood, Would it not be a good idea to glue three sides of a box section mast together, then dump a lot of salt in before gluing it up? Perhaps it is a good time to try an experiment, by soaking a couple of pieces of spruce in strong salt brine , drying it out, then gluing it, to see if the salt affects the strength of the glue line? Any thoughts from the wood experts?
Not sure about pickling with salt, but what about penetrating epoxy....though a spar maker actually suggested resourcenol was a better adhesive to use than epoxy because it held up better to flexing.
As I pointed out earlier my mast is laminated (glued with resourcenol)and solid, the sheaves are actually cheek blocks on the outside of the mast (the one lower down is a loose block attached to a pad eye. The mast step is a square hole cut in the cabin sole sitting on top of a floor (with an opening on the side so if any water gets into the mast step it will drain into the bilge. Most sites of mast rot have been avoided where possible, my 40 year old mast is quite sound.
