Brief Description: Check diameter of main spar bolt holes
My main spar bolt holes appeared to fit the bolts just fine. However, Lauren's spar holes are loose on the bolts, so he borrowed Zenith's set of Meyer Gage Pins. The specs of these gages is:
Class Z £ Size deviation .0001” £ Roundness geometry .00005” £ Surface finish 8 micro
As I expected, the 5/16" (0.3125") gage fit my holes very tightly. The next size pin, 0.3225," would not go into the holes at all.
I checked all the holes on both main spars and the center spar. They were all tight on the 5/16" pin.
