BBSS Inspection Fixture Fit-Checked

BBSS Inspection Fixture (D2200364) parts were fit-checked and helicoiled. Since we need the actual container for the full assembly, I tried to assemble everything but that which was:

1. Inspection Ring Assembly - ~100 "feet" (D2400031) were helicoiled, 12 of which were attached successfully to the inspection rings (which also were helicoiled)

2. The locating shaft (D1000347) and sleeve (D1000346) were fit-checked with the set screw and helicoiled. The 3/8-16 screws that go into the helicoils are too tight for some to go in so I left the tangs in until I can investigate either. This is the only weird thing I encountered.

3. Wing nuts and other holes were fit-checked and fit well and easy.
