Brief Description: Fit and mark, W907 B C D E, Counter sink , dimple
10/4/2013 - 10/10/2013
W 907 B C D E have been double and triple checked to make sure what holes need countersinking and dimpling. Also double checked holes that will attach doublers to spars and what hole TO NOT rivet. Also verified that W907 E last three holes need to be dimpled rather than counter sunk. Some builder sites show counter sinking, but per Vans Aircraft, metal is too thin to be counter sunk. Vans says to dimple. Countersunk W907 C. Prepped and primed B C D E.
