Thats what I thought Arthur P just confirming. Hey Len, I see you peeking. I don' t think I answered about the method I use for finding the stiff/weak side of an arrow shaft. I am not too good at explaining things in writing but I will try. What I do is take 3 small sealed ball bearings with an inside bore diameter just slightly larger than the diameter of the shaft (where I originally read it the suggested using the bearings from a skateboard wheel). Remove the seals from both sides and flush ot the stiff grease that is usually packed in there so the bearings can rotate as freely as possible.

I then run the arrow shaft thru all 3 bearings. With the three bearings on the shaft, I support the two outer bearings on small blocks of wood(about the size of children' s play blocks) with a " V" cut on each one to keep the bearings in place. Then press down on the center bearing to put a considerable flex in the shaft. If you then rotate the shaft from the end slowly, you can feel the stiff point as it rolls around. There will actually feel to be 2 stiff side 180 deg. apart and 2 weaker sides. With careful feel you can find the actual stiffest and weakest sides. I then mark the most stiff point with whiteout etc. and that is where I align my cock fletch. I hope this explains enough to get the idea. If not just say so and I will try again or try to figure out how to make a drawing.

I know this is not as accurate as a spine tester but works fairly well for my amature use. I think I paid $10-$12 for three bearings at the supply house. I really noticed a difference in grouping when I started doing this.
