Arrow_Spine_Bearing_Jig

thingiverse

This design relies on bearings I had available. ABEC-5 Bearing 10x19x5 is used as a support in testing arrow spine. Four bearings and two of each part are needed, as they hold the carbon arrow shaft at a distance of 28 inches with a 2-pound weight suspended from the center of the shaft.
