I have been reading books on various subjects relating to woodworking, spar making, and ship rigging. I'll have to put a bibliography on my webpage. Each time I learn and finish one thing I have to learn something new for the next part. The process of figuring out how I ought to make the yard arm and then how to go about it, and then actually do it started in mid april. Now that I know how to do a hollow spar I hope to have the two topmasts finished by the end of July.
I am not sure how much weight it reduces it by, but it is significant. It is also stiffer and stronger. A tube of any material is stronger than a solid rod. Since this spar will be about 30 off the deck, each ten lbs I reduce the weight by reduces the torque it creates by 300 lbs. 10 lbs x 30 feet turning arm = 300 foot lbs.
How do you know how to do all this?

I'm guessing you do all that stuff to cut down on weight....?
Why not just use a solid piece of wood?

I guess I'm trying to ask "how much weight does all this really cut down? If that's why you're doing it.
