There are two HS-411PP brackets, but only HS-411BPP is pre-punched for the VA-146 attach holes (See Exploded Iso View). Clamp HS-411APP and HS-411BPP around the VA-146 bearing and cleco the assembly to the spar.
Using HS-411BPP as a drill guide match drill and cleco the aft four VA-146 attach holes.
Remove the assembly from the spar and match drill the forward two VA-146 attach holes.
Deburr the parts, prime VA-146 if desired, then rivet them together (the –5 rivet is the correct length, see Section 5.4). This sort of one at a time priming makes having a spray can self etching primer nice.
- I really laboured about this rivet size. To me the rivet seems too small (but only marginally). But the instructions are very specific here ("the –5 rivet is the correct length, see Section 5.4") unlie elsewhere in the text where it justmakes a call-out. Further, most other builders on Vans Airforce seemed to have run with this rivet size also.
