This session was mostly spent on fabricating and fitting the seat back adjustment supports to the F-705F. Matched drilled parts to F-705F. Put slight bend in F-705 plate by clamping part between two pieces of MDF and using hand seamer. Drilled bushing holes in F-705D left and right. Drilled all remaining holes to size, deburred and stored. Started deburring F-706 bulkhead parts.
