I recently put a new handle on one of my axes, Its a straight 36 inch handle on a 3 1/2 pound head. I seated it down to my prefrence, wedged it and took it out for a test. After about a half an hour of chopping I noticed around a 36th of an inch movement of the head off the handle. I chopped for another half hour and it dident move any more. Shound I be worried about the head comming off? It seems to be tight now.
