I don't think there is any worthwhile gain to go with sectional wood arrows.

I'll find that out today unless something screws up ;D

OK glued up strip Hemlock has no advantage over natural Hemlock. Two 3/8" shafts both have 75# spine. The glued one weights 474 and natural weigh 444 so the natural wins but the weight difference may come from different density wood. The glued one may have gotten the weight from the water in the glue so I'll leave them a while and re weigh but I'll not expecting any miracles. I got the same results with a flat laminated arrow I tried a while back. They say laminating makes things stronger but it doesn't seem so with arrows. Like you say Bamboo is a different thing.

It looks like a lot of activity going on here.
Laminating often improves strength, but has a much lesser effect on stiffness. The measurement of spine is a measurement of stiffness only. Stiffness and strength are two completely different properties.
I have tied other materials in hex laminated arrows with mixed results. The most important property for a flight arrow is one with a very high stiffness or modulus of elasticity. Most bamboo species, such as Moso and the species used for Yumi bows do not have much different stiffness properties than many common hardwoods. Making hex-type arrows out of these types of materials may give you a strong arrow, but not much stiffer than a decent wood arrow. Good Tonkin cane is an exception. It has two to three times the stiffness of Moso bamboo.

Thought so :)
DC get some good Tonkin as Alan says it is a different beast.
DC:
I did a quick search and can't find any. At least nobodies bragging about it. I'll phone the place I get my Moso from today.
