Tonight I trimmed and notched the F-684 lower engine mount bracket gussets per plan. I also drilled both for the nutplates that will eventually hold vent line clamps. I drew horizontal bend lines on each gusset and bent the left one to the specified 1/16". A trial fit says I'll probably have to bend it a bit more. But first I need to drill the 5 attach holes on the vertical legs.
