Brief Description: Preparing the Main Spars (LH&RH)
Tapped each W-731 tiedown bar deep enough so that a 3/8"-16 x 1/2" Socket Set plug could be installed as a hardstop when installing the tiedown ring. This in order to avoid crushing the Leading Edge skin against the tiedown eye when screwing on the ring.
Final distances measured in both LH & RH assemblies
3/8"-16x1/2" plug
This is how the ring will end up inside the W-731 tiedown bar
