Default Spruce spars source ?

Look at 'Practical Yacht Joinery" by Fred Bingham gives instructions on building
a wooden mast. Also if using clear Douglas Fir (the actual Douglas Fir not the
substitutes that many suppliers try to sell) you can reduce skantling by 10% for
a similar strength to weight ratio.

Thank you.


Aircraft Spruce sells prime sitka spruce spar stock, if you can handle
the price.
Corona, Ca 1-800 824-1930
Griffin, Ga 1-800 831-2949

Examples: 1.5 inch X 4 inch $10.40 per lineal foot plus 15% for
lengths over 12 ft. (oldish catalog prices !!)
You could route the two halves, and glue and clamp.

But as you may know, spruce is not the hardyest, the lightest, or the
strongest wood; far from it.

If you can handle the top weight, there are stronger, cheaper
whitewoods. Spruce is desired for its superior strength to weight.
That's all. You would not be cast down in Hell if you chose
cleargrain builders' studs to laminate, for example.
Cheaper by far.
