Low Cost DIY Rod Weighing Setup

I'm certainly no expert on rod weighing specifics but it seems to me that having so much weight into the jig itself would cause inaccuracy simply because it starts to become more and more of the total combined rod and jig weight. I'd think a "skeleton" jig for lack of better word that is much lighter would then allow the small change in rod weight (between rods, etc) to then be a larger overall change in comparison.

"Extremes" Let's say the jig is about equal to or double the rod weight. You could reach a point where a change in rod weight that you might desire correction would be so small in comparison to the total weight that the resolution of the scale simply will not show it up

On the other hand if you could get the jig down to say, 1/8 of the rod weight, then any change obviously becomes a larger percentage change

I give you guys credit.........You are always thinkin' !!!
