TWICE THE SCALE
I adapted this rod weighing setup after seeing my friend doing something very similar. If the point of contact with the scale is not the dead center of the bore on each end of the rod, you will not get accurate readings. I turned some mandrels on the lathe that slip fit in the rod bores. Then I made some axles out of stainless, just so that they don’t rust, and weight matched them so that it doesn’t matter if they get mixed up. This setup is repeatable to within a few tenths of a gram every time.
