Regardless, you should do some due diligence and invest in a small grain scale
and individually weigh your arrows and components.
George Washington Carver's laboratory set up of equipment he used to do his experiments which includes a: distilling apparatus, crucible holder, microscope, crucibles, reagent bottles, ring stand, steam heater, burner, peanut apothecary, grain scale
, mortar and pestle, and a centrifuge.
Section 1 on measurement contains sub-sections on local scale measurements, diffraction at grain scale
and multistate diffraction, diffraction gradients and instrumental developments, mechanical relaxation methods, and acoustics and electromagnetics methods.
In some cases the weight can double and only a grain scale
could tell the difference.
One handy little grain scale
designed for reloading ammunition but also well suited to archery is the Mini-Digital Reloading Scale from MTM Case-Gard ($40).
Researchers experimentally confirmed the higher temperature, a consequence of grain scale
property changes including resistivity and conduction, using Raman spectrometry diagnostics to obtain measurements at the submicron scale.
We use a calibrated Chattilon Digital Force Gauge and an Easton Digital Grain Scale
Then, using an electronic grain scale
and a spine tester, I measure and record the weight, straightness, and static spine of each.
Some shooters even weigh charges on a grain scale
(as opposed to volumetric measuring)--I once went to the trouble myself, but subsequent conversations with competition shooters convinced me the practice was unnecessary.
Weight: Vane-unit weight was measured using an Easton Digital Grain Scale
, calibrated according to manufacturer specifications.
I weighed several Rayzrs on my grain scale
and learned that they weigh one-third to one-quarter as much as most vanes.
