I had some guys over at Knifedogs forum ask me about "testing". My reply follows:
Testing:
I can report that the blade will bend along the 3/16" measurement axis long before the 1" round bar fails and that the shaft, the hog or a human arm/grip will fail before the blade or connector fails along the wide axis of the blade. I can tell you these things because I have rigged "things" in this manner many times before in different applications. Most of the "testing" of the spearhead to shaft connection has been done before by me and thousands of other people who have been around tools, machinery and the laws of physics.
When I get the connector made, I will clamp it to a large fixed object and all ow "Tony" (below) to, hang on it, do a few pull ups on the shaft, stand on it, jump on it and then hand it to a hog hunter to kill a few hogs with. The final version of the connector might be fabricated out of aluminum.
ps Light is not always better. Keeping a fair amount of mass in a thrusting weapon translates into inertia and more inertia means more penetration:-)
