Saracen Arrows on a girl guide site????

It finally downloaded, boy that was slow, but it looks like a very cool pdf. Thank you.

its going to bend out of the bow any way, so maybe knowing which way would be informative. I have been making replicas of NA atlatl darts. A compression test is commonly used by dartmakers to determine "spine". I have one unusual dart example that can only be placed in the atlatl/spear-thrower one way, and it is elliptical in cross section, so it is well understood which way it is going to flex first.
DC:
Yes it would be informative but can you trust a piece of wood to keep the same bend, especially after you've straightened it. But I guess that's going to happen anyway. I've been thinking a pipe clamp would work. One of those long ones with the screw thing on the end. I think they're called a pipe clamp ::) ::)
PS yes the pipe clamp worked. One arrow popped through the same every time and the other seemed to kinda prefer one area but not consistently. Bothe the arrows had the nock already cut--- wrong :D
willie:
so what I find with the darts is when you compress the dart on a scale, the force builds until the shaft springs sideways. at that point, more force causes more deflection, but the scale sort of stabilizes. hard to describe.
