Well, I made a go at creating a few bamboo arrows and decided I really don't enjoy working with bamboo.... Bamboo is just to unpredictable in my opinion. I'm trying to make these at 55-60lbs spine, and I cant figure them out. The first one started at about 55lb, after straightening and smoothing the shaft it had dropped to 40lbs, lol then it broke while bending because there was a very thin wall in an area. So next go around I figured I would start with one a little tougher at 70lb spine, after straightening and smoothing it was still up around 70lb spine.
I think I will try to find a few straight grain cedar or dug fir or ponderosa pine boards. I saw a topic the other day that mentioned ponderosa pine makes a light weight durable shaft. I should mention, I don't have a setup to cut the boards down to 3/8x3/8 square dowels. I'm going to try splitting them out of a board, like splitting kindling.
@jojodapyro,
ditto, this cold weather is making glueing a challenge, I've had to bring things inside the house.
